This reproducible R Markdown analysis was created with workflowr (version 1.6.2). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.
The results in this page were generated with repository version b1c6ad9. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.
Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish
or wflow_git_commit
). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

This research website is maintained for the documentation of the project ‘A Comparison of Bayesian Inference Techniques for Sparse Factor Models’.
With the rise of high-dimensional data, various dimension reduction techniques have emerged, with the aim of identifying underlying structures which govern the data. One of these techniques is factor analysis, an approach which aims to discover latent variables (factors) that explain the data. Given a large number of observations, each consisting of a large number of attributes, factor analysis seeks to quantify the associations between these attributes and some factors, and also the weight of each factor for each observation. Dimension reduction is achieved by having a number of factors that is far smaller than the number of attributes/observations.
If it is desired for some factors to govern only a small subset of attributes, the approach is then known as sparse factor analysis. This is because the matrix connecting the attributes to the factors will contain a significant proportion of zeros, making this loading matrix a sparse matrix.
One specific application of sparse factor models is the analysis of gene expression data. Biological theory expects that gene expression levels to be regulated by different mechanisms, which may be difficult to observe directly. Sparse factor analysis is an appropriate approach to analyse these processes, as most mechanisms (e.g. transcription factors) are each responsible for regulating only a small subset of genes. Successful inference may then shed light on the underlying gene regulatory network.
The gene expression level of gene \(i\) of individual \(j\) can be modelled as \[y_{ij} = \sum_{k=1}^K l_{ik}f_{kj} + e_{ij},\] where \(l_{ik}\) is the regulation strength of factor \(k\) on gene \(i\), \(f_{kj}\) is the activation weight of factor \(k\) for individual \(j\), and \(e_{ij}\) is a noise term. To achieve sparsity, \(l_{ik}\) is set to zero if gene \(i\) is not regulated by factor \(k\). Other details of the mathematical model are documented in the derivation.
Following a Bayesian approach, the posterior distributions of the parameters of interest (e.g. \(l_{ik}\) and \(f_{kj}\)) are intractable to calculate directly. Two techniques are investigated:
Markov Chain Monte Carlo (MCMC). The posterior distribution is approximated by simulating samples from a Markov chain which converges to the desired distribution. When successful, the target distribution will be accurately caputred, but this approach is known to be computationally intensive.
Variational Inference (VI). As the posterior distribution involves complex dependencies between the model parameters, we instead search for an approximate distribution from a family of much simpler distributions. Solving this optimisation problem is computationally more efficient than MCMC, at the cost of fidelity due to the use of simpler distributions.
The main goal of this project is to compare the performance of these two techniques, in terms of accuracy and computational efficiency. It is expected that VI should have an advantage of being the faster approach without sacrificing too much accuracy.

There’s A Dumb Theory Kylie’s Sisters, Already Rich, Are Jealous Of Her $600M Payday
by By PEDESTRIAN.TVThere’s a silly, silly theory going around about the Kardashian / Jenner family following the news of Kylie Jenner‘s latest business movie.
If you’re unaware, Kylie recently became USD$600 million richer after she sold a majority stake in her makeup company, Kylie Cosmetics, to beauty beasts Coty Inc., which is a big power move.
So then today, the Daily Mail published a yarn about how Kylie’s sisters including Kim, Kourtney, Khloé, and Kendall have apparently snubbed her big business move because they’re not posting about it on Instagram. Yes, really.
In the last day or so, Kim has used her IG Story to give a shoutout to the family’s loyal as hell friends Malika and Khadijah, who just released their own reality TV show. She also promoted her Solutionwear, the one that used to be called Kimono.
Khloé used her clout to plug perfume by “The OG trio” on her feed. But she supported Kylie’s latest Christmas collection on her IG Story.
Kourtney promoted her latest blog posts on her website Poosh as well as the perfume.
And Kendall posted a cute piccie sponsored by Proactiv, as per usual.
Mum / manager Kris Jenner also shared some promotional pictures of Kylie’s holiday collection.
With the internet being the internet, the DM’s yarn copped a lot of comments and the theory flew… and turned ugly. For example, this comment: “They’re all jealous of one another, big fallouts in the future and I cannot wait.”
Christ.
But to be honest, the family probably celebrated the big win privately or they’re gearing up for a public celebration, like what they did when Kendall landed the coveted September Vogue issue cover.
Or, ya know, maybe they’re just waiting for Kylie to actually acknowledge it on Instagram because right now, she’s knee deep in promoting her Christmas collection.

"Get Artwork from Synergy" script broken
-
rotorglow
Since....fairly recently (I'm not sure when), the (wonderful) Get Artwork From Synergy script included with Syndergy has been failing.
When run, it takes several seconds, then displays 2 messages in a dialog box titled "Select Artwork To Use:" 4021: Can't checkin with server named com.apple.metadata.mdserver, error 0x10000004 4021: Can't create query: 0x10000003
...with Cancel and Select buttons.
The 4021 changes (is it a PID?)
I'm running itunes 7.4.2, and this was happening with both Synergy 3.1.1 and 3.1.5
Synergy has already downloaded the artwork
Any thoughts? Is it a Synergy problem or did an iTunes update break the script?
Thanks for an amazing product.

Greg Hurrell
I haven't seen any messages like that, so this is speculation, but I'd say that you're might be right that 4021 is a PID; quite probable also that it could be an error number (although most Apple error numbers are displayed as negative numbers; ie. -4021).
That's actually a user-contributed script (not much of an AppleScript guru myself) so let's see if he replies (he's subscribed to this forum).
One thing you can use is the "Transfer cover to iTunes" menu item in Synergy's Global Menu, but obviously that's on a per-track basis so it's best suited for filling in holes in your collection rather than going through your entire library.
Leopard is almost out and so I'll be spending the next couple of weeks ironing out any bugs and remaining compatibility issues; then I'll be able to start on integrated support for this kind of thing (not needing to rely no external scripts to do it).

- Expansion example
This chapter describes the validation function compliant with Bean Validation (JSR349) of Java EE7.
Important
The Bean Validation engine is not implemented by this function.
Java EE environments (such as WebLogic and WildFly) use the Bean Validation implementation that is bundled in the server. For use outside Java EE environments, the Bean Validation implementation must be added to the reference library separately. (It is recommended that the reference implementation Hibernate Validator(external site) be used.)
<IP_ADDRESS>. Function overview¶
<IP_ADDRESS>.1. Can validate domains¶
Provides a function that can define validation rules for each domain.
When using domain validation, it is only necessary to specify the domain name in the Bean property, which makes changing the validation rules easy.
For details, see Use domain validation.
<IP_ADDRESS>.2. Commonly Used Validators are Provided¶
Since Nablarch provides commonly used validators, basic validations can be used without having to create anything.
For the validators provided by Nablarch, see the annotations (annotation type) in the following packages.
<IP_ADDRESS>. Module list¶
<Dependency>
<groupId>com.nablarch.framework</groupId>
<artifactId>nablarch-core-validation-ee</artifactId>
</dependency>
<!--
Only to build messages using message management
Message management is used by default
-->

</dependency>
<!-- Only when using a code value validator -->
<Dependency>

</dependency>
<!-- For use in web applications-->
<Dependency>
<groupId>com.nablarch.framework</groupId>
<artifactId>nablarch-fw-web</artifactId>
</dependency>
<IP_ADDRESS>. How to use¶
<IP_ADDRESS>.1. Configure settings to use Bean Validation¶
The configuration required to use Bean Validation are shown below.
- MessageInterpolator configuration
Configure the class that constructs the message when validation errors occur in Bean Validation (a class that implements MessageInterpolator).
If this is not configured, then NablarchMessageInterpolator which uses Message Management is used.
For example, when using the implementation that builds a message from the property file of Hibernate Validator, configure as shown below.
Important
Be sure to use component name messageInterpolator.
<!-- Specify messageInterpolator for the component name and configure the MessageInterpolator implementation class --> <compnent name="messageInterpolator" class="org.hibernate.validator.messageinterpolation.ResourceBundleMessageInterpolator"/>
- Configuration for domain validation
- See Use domain validation
- Configuration for using Bean Validation in web application
- See Checking User Input Values for Web Applications
<IP_ADDRESS>.2. Define the error message for validation error¶
As explained in Configure settings to use Bean Validation, message during an error is built using Message Management by default. Therefore, refer to Message Management for more information, such as where the message is defined.
The message definition rule when using the default NablarchMessageInterpolator is as given below.
- Build a message using Message Management only when the value specified in the
message
attribute of the annotation is enclosed within{
and}
. - A placeholder for embedding the attribute information of the validation annotation can be used in the message text.
A placeholder is defined by enclosing the attribute name of the annotation within
{
and}
. - Expressions that dynamically build messages (ex: EL expressions) cannot be used.
An example is shown below.
- Java implementation example
public class SampleForm { @Length(max = 10) @SystemChar(charsetDef = "Full-width character") @Required private String userName; @Length(min = 8, max = 8) @SystemChar(charsetDef = "Half-width character") private String birthday; // Getter and setter are omitted }
- Message definition example
Define a message using the message ID specified in the annotation as the key. When the message attribute of the annotation is not specified, the default value will be the message ID.
# Message corresponding to Length annotation # Value specified in min or max attribute of Length annotation can be embedded in the message nablarch.core.validation.ee.Length.min.message= Enter at least {min} characters. nablarch.core.validation.ee.Length.max.message= Enter no more than{max} characters nablarch.core.validation.ee.Length.min.max.message={min} Enter a value between {min} and {max} characters. # Message corresponding to SystemChar nablarch.core.validation.ee.SystemChar.message= Please enter with {charsetDef}.
Tip
When the default behavior is changed in Configure settings to use Bean Validation, the message is defined according to the MessageInterpolator implementation.
<IP_ADDRESS>.3. How to configure validation rules¶
Validation rules can be specified by configuring annotations in a Field or Property (getter). Also, note that annotations cannot be specified for a setter. (It is meaningless even if specified (will be ignored))
Tip
All the property types of Bean class should be defined as a String.
Bean Validation is performed after converting the input values to Bean. Therefore, whatever values are sent as external input values must be converted to Bean.
When a property other than String exists and an invalid value is sent (for example, if an alphabetic character is sent for a numeric type), the conversion process to Bean, which is performed before validation, fails and an unexpected exception is thrown, resulting in a failure.
Normally, a failure should not occur no matter what value is input, and the validation result should be notified externally (for example, the screen).
To convert an external value to a type other than String, convert it after validation is performed.
Even if validation is performed on the client side using JavaScript, there is no guarantee that the validated value will be sent to the server side, hence, the property must be a String. This is because the user can easily disable JavaScript and tamper with it using the browser developer tools on the client side. When such an operation is performed, there is a possibility that an invalid value will be sent to the server side, bypassing the client side validation.
- Implementation examples
Configure annotations by referring to the validators provided by Nablarch.
Tip
If annotations are configured individually, errors during implementation and maintenance costs will increase. Hence, it is recommended to use the domain validation described below.
public class SampleForm { @Length(max = 10) @SystemChar(charsetDef = "Full-width character") @Required private String userName; @Length(min = 8, max = 8) @SystemChar(charsetDef = "Half-width character") private String birthday; // Getter and setter are omitted }
<IP_ADDRESS>.4. Use domain validation¶
Show the configuration and implementation examples to use domain validation.
- Creating Bean that defines the validation rules for each domain
To use domain validation, first create an Bean (domain Bean) with validation rules for each domain.
This Bean class defines fields for each domain and configures annotations for the fields. The field name becomes the domain name. In the following example, two domains,
name
anddate
, have been defined.Tip
Configure the @Required annotation which indicates required items on the individual Bean side instead of in the domain Bean. Whether an item is required or not cannot be enforced on the domain side, since it depends on the function design.
package sample; import nablarch.core.validation.ee.Length; import nablarch.core.validation.ee.SystemChar; public class SampleDomainBean { @Length(max = 10) @SystemChar(charsetDef = "Full-width character") String name; @Length(min = 8, max = 8) @SystemChar(charsetDef = "Half-width character") String date; }
- Domain Bean Enabled
To enable the domain bean, create the implementation class DomainManager. getDomainBean returns the domain Bean class object.
package sample; public class SampleDomainManager implements DomainManager<SampleDomainBean> { @Override public Class<SampleDomainBean> getDomainBean() { // Returns the Class object for the domain bean return SampleDomainBean.class; } }
By defining SampleDomainBean of the DomainManager implementation class in the component configuration file, domain validation using SampleDomainBean will be enabled.
<!-- DomainManager implementation class should be configured with the name domainManager --> <component name="domainManager" class="sample.SampleDomainManager"/>
- Use domain validation for each Bean
Domain validation is performed by configuring the @Domain annotation to the bean properties to be validated.
In this example, validation configured in the name field of SampleDomainBean is performed for userName. Similarly, validation configured in the date field is performed for birthday.

public class SampleForm { @Domain("name") @Required private String userName; @Domain("date") private String birthday; // Getter and setter are omitted }
<IP_ADDRESS>.5. Performing Character Type Validation¶
Validation by character type can be performed using the validation function of system allowed characters.
To perform validation by character type, define the character set for each character type.
For example, it is necessary to define that half-width numbers from 0
to 9
are allowed in the character type of half-width numbers.
The method of defining allowed character sets for each character type is shown below.
- Define the allowed character set in the component definition
The set of allowed characters is registered using any one of the following classes. During registration, configure the component name to an arbitrary name that indicates the character type.
- RangedCharsetDef (Used when registering the allowed character sets in the range)
- LiteralCharsetDef (Used when registering all allowed character sets in the literal)
- CompositeCharsetDef (Used when registering allowed characters consisting of multiple RangedCharsetDef and LiteralCharsetDef)
A configuration example is shown below.
<!-- Half-width number --> <component name="Half-width number" class="nablarch.core.validation.validator.unicode.LiteralCharsetDef"> <property name="allowedCharacters" value="01234567890" /> <property name="messageId" value="numberString.message" /> </component> <!-- ASCII (excluding control code) --> <component name="ascii" class="nablarch.core.validation.validator.unicode.RangedCharsetDef"> <property name="startCodePoint" value="U+0020" /> <property name="endCodePoint" value="U+007F" /> <property name="messageId" value="ascii.message" /> </component> <!-- Alphanumeric --> <component name="Alphanumeric" class="nablarch.core.validation.validator.unicode.CompositeCharsetDef"> <property name="charsetDefList"> <list> <!-- Definition of half-width number --> <component-ref name="Half-width number" /> <!-- Definition of half-width characters --> <component class="nablarch.core.validation.validator.unicode.LiteralCharsetDef"> <property name="allowedCharacters" value="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" /> </component> </list> </property> <property name="messageId" value="asciiAndNumberString.message" /> </component>
- Specify the character type with annotation
Configure the @SystemChar annotation in the property that performs character type validation. Configure the name indicating the allowed character type in the charsetDef attribute of this annotation. This name will be the component name when the character type set is registered in the component configuration file mentioned above.
Since
half-width numbers
have been specified in this example, “0123456789” are allowed as per the component definition mentioned above.public class SampleForm { @SystemChar(charsetDef = "Half-width character") public void setAccountNumber(String accountNumber) { this.accountNumber = accountNumber; } }
Tip
When there are a large number of characters in the set of allowed characters, it takes time to check the characters that are defined after. (To simply check whether the characters are included in the character set in order from the beginning) To solve this problem, provide a mechanism to cache the results of a character once it has been checked.
- In principle, it is advisable to proceed with development without using the cache function, and consider using the cache function if character type validation becomes a bottleneck.
Usage is simple. Configure the definition of the original character type set to CachingCharsetDef for caching, as in the component definition shown below.
<component name="Half-width character" class="nablarch.core.validation.validator.unicode.CachingCharsetDef">
<property name="charsetDef">
<component class="nablarch.core.validation.validator.unicode.LiteralCharsetDef">
<property name="allowedCharacters" value="01234567890" />
</component>
</property>
<property name="messageId" value="numberString.message" />
</component>
- Allowing Surrogate Pairs
This validation does not allow surrogate pairs by default. (They are not allowed even if the characters for surrogate pairs are explicitly defined in LiteralCharsetDef.)
To allow surrogate pairs, SystemCharConfig must be configured in the component configuration file as follows.
- Point
- The component name should be
ee.SystemCharConfig
- The component name should be
<component name="ee.SystemCharConfig" class="nablarch.core.validation.ee.SystemCharConfig"> <!-- Allows surrogate pairs --> <property name="allowSurrogatePair" value="true"/> </component>
<IP_ADDRESS>.6. Performing Correlation Validation¶
To perform correlation validation using multiple items, use the @AssertTrue annotation of Bean Validation.
- Implementation examples
In this example, it has been verified that the email address and the confirmation email address match. When a verification error occurs, the message specified in the message property becomes the error message.
public class SampleForm { private String mailAddress; private String confirmMailAddress; @AssertTrue(message = "{compareMailAddress}") public boolean isEqualsMailAddress() { return Objects.equals(mailAddress, confirmMailAddress); } }
Important
Since the execution order of the validation is not guaranteed in Bean Validation, correlation validation may be called even before the validation of individual items.
Therefore, it is necessary to implement validation logic so that unexpected exceptions do not occur, even if the validation of individual items is not executed in correlation validation.
If mailAddress and confirmMailAddress are optional items in the example above, a result must be returned without executing validation if they have not been input.
@AssertTrue(message = "{compareMailAddress}")
public boolean isEqualsMailAddress() {
if (StringUtil.isNullOrEmpty(mailAddress) || StringUtil.isNullOrEmpty(confirmMailAddress)) {
// If either of them is not input, correlation validation is not performed.(Validation is OK)
return true;
}
return Objects.equals(mailAddress, confirmMailAddress);
}
<IP_ADDRESS>.7. Performing Correlation Validation with the Database¶
Correlation validation with the database is implemented on the business action side for the following reasons.
- Reason
When correlation validation is performed for the database using Bean Validation, the database is accessed using the unsafe value before validation is performed. (There is no guarantee that the value of the object during Bean Validation is safe.) This is an implementation that should be avoided as it causes vulnerabilities such as SQL injection.
By validating with a business action after validation is performed, the database can be accessed using the validated safe value.
<IP_ADDRESS>.8. To create a validation error message linked to a specific item¶
When an error occurs in the validation performed with action handlers such as Correlation validation with the database, sometimes it may be required to highlight the target item as an error on the screen.
In this case, as shown in the implementation example below, an error message is built using ValidationUtil#createMessageForProperty and the ApplicationException is thrown.
throw new ApplicationException(
ValidationUtil.createMessageForProperty("form.mailAddress", "duplicate.mailAddress"));
<IP_ADDRESS>.9. Performing validation using a function that performs Bean multiple input, such as batch registration¶
There are cases where the same information is input multiple times, such as in batch registration. In such cases, a nested Bean is defined for the Bean for validation.
Tip
Since this is the specifications for Bean Validation, see Bean Validation specifications for details.
An example is shown below.
// Form that stores all the information that has been batch input
public class SampleBulkForm {
// Configure the Valid annotation that indicates
// validation is also executed for nested Bean.
@Valid
private List<SampleForm> sampleForm;
public SampleBulkForm() {
sampleForm = new ArrayList<>();
}
// Getter and setter are omitted
}
// Form that retains the information of one input of the information that is input in batch
public class SampleForm {
@Domain("name")
private String name;
// Getter and setter are omitted
}
<IP_ADDRESS>.10. Important points when validating nested Bean¶
Nested bean information may not be sent, for example, when the html is tampered with a browser developer tool and the web service receives an invalid Json or XML, etc. In this case, the nested Bean becomes uninitialized (null) and will not be a target for validation. Hence, implementation is required so that the status of the nested Bean can be reliably validated.
Some implementation examples are shown below.
- When parent Bean and nested Bean are 1:N
The nested Bean will be a target for validation, and the fields of the nested Bean are also initialized when the parent Bean is initialized. If the information of nested Bean is required (select or input at least one), configure the Size annotation.
// Validates that at least one is selected by configuring the Size annotation. @Valid @Size(min = 1, max = 5) private List<SampleNestForm> sampleNestForms; public SampleForm() { // Initialize the fields of the nested Bean when creating an instance sampleNestForms = new ArrayList<>(); }
- When parent Bean and nested Bean are 1:1
Consider whether a flat Bean can be made without nesting the Bean. When unable to respond to requests from the connection destination, perform implementation so that nested Bean validation can be executed reliably.
// Target nested Beans for validation @Valid private SampleNestForm sampleNestForm; public SampleForm() { // Initialize the fields of the nested Bean when creating an instance sampleNestForm = new SampleNestForm(); }
<IP_ADDRESS>.11. Checking User Input Values for Web Applications¶
The user input values for web applications are checked using InjectForm Interceptor. For details, see InjectForm Interceptor.
To use Bean Validation with InjectForm Interceptor, it must be defined in the component configuration file.
As shown in the example below, Define a component definition of BeanValidationStrategy with the name validationStrategy
.
<component name="validationStrategy" class="nablarch.common.web.validator.BeanValidationStrategy" />
Tip
BeanValidationStrategy sorts the error messages for validation errors in the following order.
- Order of item names returned by javax.servlet.ServletRequest#getParameterNames (If the item in which the error occurred does not exist in the request parameter, it is moved to the end)
Note that the value returned by getParameterNames
is implementation-dependent, and the alignment order may change depending on the application server used.
To change the sort order in the project, BeanValidationStrategy is inherited.
<IP_ADDRESS>.12. Request parameters are to be obtained from the request scope even when there is a validation error¶
When InjectForm Interceptor is used, the validated Form is stored in the request scope after successful validation. This can be used to reference the request parameters, but there may also be similar cases where you would like to get the parameters from the request scope when a validation error occurs.
For example, the following process must be added when using the JSTL tag (EL expression), since it is not possible to implicitly refer to [2] the request parameters unlike with the Nablarch custom tag.
- Use Nablarch tag
<n:set>
once to store the values of request parameters in a variable. - Access request parameters using the implicit object
param
An example using the former <n:set>
is shown below.
<%-- Substitutes the values of request parameters in a variable so that they can be referenced even with JSTL (EL expression) --%>
<n:set var="quantity" name="form.quantity" />
<c:if test="${quantity >= 100}">
<%-- When the quantity is 100 or more... --%>
In such a case, the Bean that copied the request parameters can be stored in the request scope
even when a validation error occurs by configuring the property copyBeanToRequestScopeOnError
of
BeanValidationStrategy to true
.
A configuration example is shown below.
<component name="validationStrategy" class="nablarch.common.web.validator.BeanValidationStrategy">
<!-- Copies values to the request scope when a validation error occurs -->
<property name="copyBeanToRequestScopeOnError" value="true"/>
</component>
The Bean is stored in the request scope using a key specified with the name
@InjectForm
(same as normal operation of InjectForm Interceptor).
By enabling this function, the JSP mentioned above can be described as follows.
<%-- Request parameter values can also be referenced with JSTL (EL expression) via request scope --%>
<c:if test="${form.quantity >= 100}">
<%-- When the quantity is 100 or more... --%>
| [2] | For a description of how the Nablarch custom tag works, see Rules to access input/output data. |
<IP_ADDRESS>.13. Embed the item name in the message when a validation error occurs¶
Although the item name cannot be embedded in the message as per the Bean Validation (JSR349) specifications, you may want to embed the item name in the message according to the requirements etc. Therefore, Nablarch provides a function that embeds the item name of the item in which an error has occurred, even if Bean Validation is used.
The usage method is shown below.
- Component configuration file
Configure the factory class that generates the message converter which embeds the item name in a message. Configure
constraintViolationConverterFactory
in the component name and ItemNamedConstraintViolationConverterFactory in the class name.<component name="constraintViolationConverterFactory" class="nablarch.core.validation.ee.ItemNamedConstraintViolationConverterFactory" />
- Form to be validated
package sample; public class User { @Required private String name; @Required private String address; }
- Definition of item name
Item names are defined as messages. The message ID of item name is the fully qualified class name for validation + ”.” + item property name.
In the case of the above Form class,
sample.User
is a fully qualified name with 2 properties-name
andaddress
. As shown below,sample.User.name
andsample.User.address
are required to define the item name.If the item name is not defined, it will not be added in the message.
# Required message nablarch.core.validation.ee.Required.message= Please enter # Definition of item name sample.User.name = User name sample.User.address = Mailing address
- Generated Message
In the generated message, the item name is added to the beginning of the error message. Item name is enclosed by
[
,]
.[User Name] Please enter. [Mailing Address] Please enter.
Tip
To change the method of adding the item name to the message, see ItemNamedConstraintViolationConverterFactory and add the implementation on the project side.
<IP_ADDRESS>. Expansion example¶
<IP_ADDRESS>.1. To add project-specific annotations and validation logic¶
If the requirements cannot be satisfied with the validators described in Commonly Used Validators are Provided, annotations and validation logic are added on the project side.
For details on the implementation method, see the following links and Nablarch implementation.


public final class URL extends Object implements Serializable
URL
represents a Uniform Resource
Locator, a pointer to a "resource" on the World
Wide Web. A resource can be something as simple as a file or a
directory, or it can be a reference to a more complicated object,
such as a query to a database or to a search engine. More
information on the types of URLs and their formats can be found at:
Types of URL
In general, a URL can be broken into several parts. Consider the following example:
http://www.example.com/docs/resource1.html
The URL above indicates that the protocol to use is
http
(HyperText Transfer Protocol) and that the
information resides on a host machine named
www.example.com
. The information on that host
machine is named /docs/resource1.html
. The exact
meaning of this name on the host machine is both protocol
dependent and host dependent. The information normally resides in
a file, but it could be generated on the fly. This component of
the URL is called the path component.
A URL can optionally specify a "port", which is the
port number to which the TCP connection is made on the remote host
machine. If the port is not specified, the default port for
the protocol is used instead. For example, the default port for
http
is 80
. An alternative port could be
specified as:
http://www.example.com:1080/docs/resource1.html
The syntax of URL
is defined by RFC 2396: Uniform
Resource Identifiers (URI): Generic Syntax, amended by RFC 2732: Format for
Literal IPv6 Addresses in URLs. The Literal IPv6 address format
also supports scope_ids. The syntax and usage of scope_ids is described
here.
A URL may have appended to it a "fragment", also known as a "ref" or a "reference". The fragment is indicated by the sharp sign character "#" followed by more characters. For example,
http://java.sun.com/index.html#chapter1
This fragment is not technically part of the URL. Rather, it
indicates that after the specified resource is retrieved, the
application is specifically interested in that part of the
document that has the tag chapter1
attached to it. The
meaning of a tag is resource specific.
An application can also specify a "relative URL", which contains only enough information to reach the resource relative to another URL. Relative URLs are frequently used within HTML pages. For example, if the contents of the URL:
contained within it the relative URL:http://java.sun.com/index.html
it would be a shorthand for:FAQ.html
http://java.sun.com/FAQ.html
The relative URL need not specify all the components of a URL. If the protocol, host name, or port number is missing, the value is inherited from the fully specified URL. The file component must be specified. The optional fragment is not inherited.
The URL class does not itself encode or decode any URL components
according to the escaping mechanism defined in RFC2396. It is the
responsibility of the caller to encode any fields, which need to be
escaped prior to calling URL, and also to decode any escaped fields,
that are returned from URL. Furthermore, because URL has no knowledge
of URL escaping, it does not recognise equivalence between the encoded
or decoded form of the same URL. For example, the two URLs:
http://foo.com/hello world/ and http://foo.com/hello%20worldwould be considered not equal to each other.
Note, the URI
class does perform escaping of its
component fields in certain circumstances. The recommended way
to manage the encoding and decoding of URLs is to use URI
,
and to convert between these two classes using toURI()
and
URI.toURL()
.
The URLEncoder
and URLDecoder
classes can also be
used, but only for HTML form encoding, which is not the same
as the encoding scheme defined in RFC2396.

public URL(String protocol, String host, int port, String file) throws MalformedURLException
URL
object from the specified
protocol
, host
, port
number, and file
.
host
can be expressed as a host name or a literal
IP address. If IPv6 literal address is used, it should be
enclosed in square brackets ('['
and ']'
), as
specified by RFC 2732;
However, the literal IPv6 address format defined in RFC 2373: IP
Version 6 Addressing Architecture is also accepted.
Specifying a port
number of -1
indicates that the URL should use the default port for the
protocol.
If this is the first URL object being created with the specified
protocol, a stream protocol handler object, an instance of
class URLStreamHandler
, is created for that protocol:
URLStreamHandlerFactory
as the stream handler factory,
then the createURLStreamHandler
method of that instance
is called with the protocol string as an argument to create the
stream protocol handler.
URLStreamHandlerFactory
has yet been set up,
or if the factory's createURLStreamHandler
method
returns null
, then the constructor finds the
value of the system property:
If the value of that system property is notjava.protocol.handler.pkgs
null
,
it is interpreted as a list of packages separated by a vertical
slash character '|
'. The constructor tries to load
the class named:
where <package> is replaced by the name of the package and <protocol> is replaced by the name of the protocol. If this class does not exist, or if the class exists but it is not a subclass of<package>.<protocol>.Handler
URLStreamHandler
, then the next package
in the list is tried.
If this class does not exist, or if the class exists but it is not a subclass of<system default package>.<protocol>.Handler
URLStreamHandler
, then a
MalformedURLException
is thrown.
Protocol handlers for the following protocols are guaranteed to exist on the search path :-
Protocol handlers for additional protocols may also be available.http, https, file, and jar
No validation of the inputs is performed by this constructor.

indicates that the URL
should use a default stream handler for the protocol, as outlined
for:

public URL(URL context, String spec) throws MalformedURLException
The reference is parsed into the scheme, authority, path, query and fragment parts. If the path component is empty and the scheme, authority, and query components are undefined, then the new URL is a reference to the current document. Otherwise, the fragment and query parts present in the spec are used in the new URL.<scheme>://<authority><path>?<query>#<fragment>
If the scheme component is defined in the given spec and does not match the scheme of the context, then the new URL is created as an absolute URL based on the spec alone. Otherwise the scheme component is inherited from the context URL.
If the authority component is present in the spec then the spec is treated as absolute and the spec authority and path will replace the context authority and path. If the authority component is absent in the spec then the authority of the new URL will be inherited from the context.
If the spec's path component begins with a slash character "/" then the path is treated as absolute and the spec path replaces the context path.
Otherwise, the path is treated as a relative path and is appended to the context path, as described in RFC2396. Also, in this case, the path is canonicalized through the removal of directory changes made by occurrences of ".." and ".".
For a more detailed description of URL parsing, refer to RFC2396.

Two URL objects are equal if they have the same protocol, reference equivalent hosts, have the same port number on the host, and the same file and fragment of the file.
Two hosts are considered equivalent if both host names can be resolved into the same IP addresses; else if either host name can't be resolved, the host names must be equal without regard to case; or both host names equal to null.
Since hosts comparison requires name resolution, this operation is a blocking operation.

MySQL is a common open source relational database for creating, reading, updating and deleting data in Python web applications. Let's learn how to install MySQL on Ubuntu 16.04 and then run a few SQL queries within the command line client.
We will not go over connecting via Python applications using object-relational mappers (ORMs) but these steps can be used as a prerequisite to working with an ORM such as SQLAlchemy or Peewee.
In this tutorial we'll use the following components:
We can install MySQL by using the apt
package manager. First make sure
your packages list are up to date. Open the terminal and run this apt
command.
sudo apt-get update
We need to install the mysql-server
package, which downloads the required
files, configures the initial database set up and handles running MySQL
as a system service. Run this apt
command to get the process started.
sudo apt-get install mysql
Enter 'y' when prompted with whether or not you want to install the new package.
An administrative screen asking for a new root password will appear in the middle of the package installation process. Enter your chosen new password twice and the installation will continue.
In a moment the installation will finish and you'll be back at the command prompt.
MySQL is now installed with a root user. However, we do not want to have our applications connect to the database with that user, so next we will create a new non-root user.
MySQL is installed with a basic configuration meant for development and testing purposes. However, the configuration is not secure for production enviroments, therefore it comes with a utility to handle basic security. Run the following command and answer the questions based on your environment requirements.
sudo mysql_secure_installation
When you finish running the script you should see the following output and be back at the command prompt.
Our MySQL instance has basic security in place but we need to create a non-root user for applications to interact with the database.
To create a non-root user, connect to the MySQL instance with the
mysql
command line client.
mysql -u root -p
Now use the CREATE USER
command to generate a new user. Make sure to
change "mynewuser" and "goodPassword" with your own values.
CREATE USER 'mynewuser'@'localhost' IDENTIFIED BY 'goodPassword';
No output after the command is good - that means the command succeeded.
We need to apply privileges to the new user so it can handle basic database operations. Again, make sure to replace the default username in this command with your new username.
GRANT ALL PRIVILEGES ON * . * TO 'mynewuser'@'localhost';
It's a good idea to reload the privileges to make sure our new user's permissions are in place.
FLUSH PRIVILEGES;
Now that our permissions are reloaded we can connect with the new user.
We're set to connect to the database with our new user. Exit the MySQL client with "Ctrl-d". Reconnect using a slightly different command than we used earlier.
mysql -u mynewuser -p
Create a new database with the CREATE DATABASE
command.
CREATE DATABASE fullstackpython;
Connect to the new database with the USE
command.
use fullstackpython;
Create a simple new table with the CREATE TABLE
command.
CREATE TABLE pages (name VARCHAR(50), url VARCHAR(1024));
Our table is ready to go - we can interact with it using the
SELECT
, INSERT
, UPDATE
and DELETE
SQL commands.
We now have our MySQL instance installed and ready for interaction. Take a look at the MySQL, relational databases and object-relational mappers (ORMs) pages for more tutorials.

An exclusive inside look at how artificial intelligence and machine learning work at Apple
A fascinating look at how ML work is being done at Apple, and how it meshes with privacy of user data and the "Apple way" of absolute secrecy.
Apple’s penchant for secrecy puts it at a disadvantage against competitors who encourage their star computer scientists to widely share research with the world. “Our practices tend to reinforce a natural selection bias — those who are interested in working as a team to deliver a great product versus those whose primary motivation is publishing,” says Federighi. If while improving an Apple product scientists happen to make breakthroughs in the field, that’s great. “But we are driven by a vision of the end result,” says Cue.
The 9 Deep Learning Papers You Need To Know About
A great overview of some recent breakthrough research in CNNs.
[...] a lot of the new and important developments in the field of computer vision and convolutional neural networks. [...] The first half of the list (AlexNet to ResNet) deals with advancements in general network architecture, while the second half is just a collection of interesting papers in other subareas.
Language Translation with Deep Learning and the Magic of Sequences
The magic of sequence-to-sequence learning, taking a crack at the 'holy grail' of Computational Lingustics: Machine Translation
What if we took two RNNs and hooked them up end-to-end? The first RNN could generate the encoding that represents a sentence. Then the second RNN could take that encoding and just do the same logic in reverse to decode the original sentence again [...] what if (and here’s the big idea!) we could train the second RNN to decode the sentence into Spanish instead of English?
With promising results:
Machine learning researchers only invented this two years ago, but it’s already performing as well as statistical machine translation systems that took 20 years to develop.
And wider applications:
About a year ago, researchers at Google showed that you can use sequence-to-sequence models to build AI bots.
And:
[...] by replacing the first RNN with a Convolutional Neural Network [...] we can turn pictures into words (as long as we have lots and lots of training data)!
Andrej Karpathy expanded on these ideas to build a system capable of describing images in great detail by processing multiple regions of an image separately.
Text summarization with TensorFlow
I wish Google will stop stealing all our research topics. :P
We’ve observed that due to the nature of news headlines, the model can generate good headlines from reading just a few sentences from the beginning of the article. Although this task serves as a nice proof-of-concept, we started looking at more difficult datasets where reading the entire document is necessary to produce good summaries. In those tasks training from scratch with this model architecture does not do as well as some other techniques we’re researching, but it serves as a baseline.
It feels like TensorFlow (and SyntaxNet) is really taking the NLP world by storm, especially looking at Google's offerings at ACL 2016.
Segmenting and refining images with SharpMask
Not wanting to be left out, Facebook has also released some incredible research in the past few weeks, earlier with fastText and now extending to DeepMask and SharpMask:
DeepMask employs a fairly traditional feedforward deep network design. In such networks, with progressively deeper network stages information is more abstract and semantically meaningful. For example, early layers in a deep net might capture edges and blobs, while upper layers tend to capture more semantic concepts such as the presence of an animal's face or limbs. By design, these upper-layer features are computed at a fairly low spatial resolution (for both computational reasons and in order to be invariant to small shifts in pixel locations). This presents a problem for mask prediction: The upper layer features can be used to predict masks that capture the general shape on an object but fail to precisely capture object boundaries.
Which brings us to SharpMask. SharpMask refines the output of DeepMask, generating higher-fidelity masks that more accurately delineate object boundaries. While DeepMask predicts coarse masks in a feedforward pass through the network, SharpMask reverses the flow of information in a deep network and refines the predictions made by DeepMask by using features from progressively earlier layers in the network. Think of it this way: To capture general object shape, you have to have a high-level understanding of what you are looking at (DeepMask), but to accurately place the boundaries you need to look back at lower-level features all the way down to the pixels (SharpMask). In essence, we aim to make use of information from all layers of a network, with minimal additional overhead.
They've also done some work on real time (video) classification:
In addition, our next challenge will be to apply these techniques to video, where objects are moving, interacting, and changing over time. We've already made some progress with computer vision techniques to watch videos and understand and classify what's in them in real time.


In traditional database software, the technology of primary key generation is mostly required. For MySQL, it is difficult to generate the global unique ID for different actual tables after Sharding. A simple solution is to generate the global unique ID by setting the rule of global ID generation, but this requires additional maintenance and also restricts the extensibility of the framework. There are a number of third-party solutions that can solve this problem, such as UUID which relies on specific algorithms to generate global unique primary keys, or other ID generation services. If Sharding-JDBC is strongly dependent on any of the above solutions, its growth will be limited. For those reasons, we finally decided to detach the underlying implementation of ID generation from Sharding-JDBC and use the JDBC interface to access to the generated IDs.
It includes: 1. Configure the auto-generating method for primary key. 2. Obtain the generated keys
Configure the auto-generating method for primary key:
TableRuleConfiguration tableRuleConfig = new TableRuleConfiguration();
tableRuleConfig.setLogicTable("t_order");
tableRuleConfig.setKeyGeneratorColumnName("order_id");
Configure the implementation class of the ID generator, and the class needs to implement the interface of io.shardingjdbc.core.keygen.KeyGenerator.
Configure the global ID generator(com.xx.xx.KeyGenerator):
ShardingRuleConfiguration shardingRuleConfig = new ShardingRuleConfiguration();
shardingRuleConfig.setDefaultKeyGeneratorClass("com.xx.xx.KeyGenerator");
Sometimes if you want the ID generator of some tables are different from the global ID generator, you can use com.xx.xx.OtherKeyGenerator to generate ID. For example, you can use com.xx.xx.OtherKeyGenerator to generate ID for t_order_item table, but com.xx.xx.KeyGenerator for t_order table.
TableRuleConfiguration tableRuleConfig = new TableRuleConfiguration();
tableRuleConfig.setLogicTable("t_order");
tableRuleConfig.setKeyGeneratorColumnName("order_id");
tableRuleConfig.setKeyGeneratorClass("com.xx.xx.OtherKeyGenerator");
To Obtain the generated keys by using the API provided by JDBC. For Statement, you can callstatement.execute("INSERT ...", Statement.RETURN_GENERATED_KEYS)
to 通知需要返回的生成的键值。For PreparedStatement, the command is connection.prepareStatement("INSERT ...", Statement.RETURN_GENERATED_KEYS)
.
To call statement.getGeneratedKeys()
to get the ResultSet of the value。
Learn about the configurations of Spring，YAML，MyBatis and JPA(Hibernate), please refer to The project examples。
Its class name: io.shardingjdbc.core.keygen.DefaultKeyGenerator
This class uses snowflake algorithm to generate 64-bit and long-type primary key which should be save in a NUM column whose length is >= 64 bits, such as BIGINT in MySQL.
Its binary representation consists of four parts: 1 bit for symbol-bit (0), 41 bits for time-bit, 10 bits for process-bit and 12 bits for sequence-bit.
The number of milliseconds from 00:00 on Nov 1, 2016 to the present and the high limit of year is 2156.
This flag is unique in the Java process, and you should ensure that every process ID is different in distributed applications. The default value is 0, and can be configured by calling DefaultKeyGenerator.setWorkerId("xxxx")
.
It is used to generate different IDs in one millisecond. If the amount of generated IDs in this millisecond is more than 4096(2 to the power 12), the generator will not generate ID until the next millisecond.
In consider of the generating method of primary key, generated ID is always sequential in product environment, which provides efficient insertion for index columns, e.g. the primary key in MySQL’s Innodb storage engine. More details on the guarantee of primary key uniqueness are as follows: First, different process numbers, different IDs. Second, Time-bit and Sequence-bit are used to ensure to generate unique ID in the same process. At last, the number of the time is monotonically increasing, and time synchronously mechanism among servers.

Design Principles¶
Distributions are the fundamental building blocks of a POMDP.
Essentially, a POMDP describes the interaction between an agent and the environment. The interaction is formally encapsulated by a few important generative probability distributions. The core of pomdp_py is built around this understanding. The interfaces in
pomdp_py.framework.basics
convey this idea. Using distributions as the building block avoids the requirement of explicitly enumerating over \(S,A,O\).
–
POMDP = agent + environment
Like above, the gist of a POMDP is captured by the generative probability distributions including the
TransitionModel
,ObservationModel
,RewardModel
. Because, generally, \(T, R, O\) may be different for the agent versus the environment (to support learning), it does not make much sense to have the POMDP class to hold this information; instead, Agent should have its own \(T, R, O, \pi\) and the Environment should have its own \(T, R\). The job of a POMDP is only to verify whether a given state, action, or observation are valid. SeeAgent
andEnvironment
.


A cookie is a text only string (less than 4KB) that is sent from a web server to a client’s hard drive via the browser. This text only string is sent and stored as a name-value pair. For example if the web server wants to track the number of visits the name may be “visits” and the value is set to 1 on the first visit, and incremented on subsequent visits. This data is stored for a given website based on its root URL, and can be retrieved at a later time by the website. This allows user preferences or user state to be saved without the need to log into the website.
In Google Chrome go to the Chrome web store and search for “cookies”. You will find apps like “Edit This Cookie”, which can be downloaded and used to view/edit/delete cookies.
Cookies allow a user to set personalization settings on a website for unauthorized users, which are users that have not yet logged into the website. A movie show times website may ask your current postal code in order to show cinemas close by. These preferences can be stored in cookie in one of the three following ways.
In the following example the website requests the users' favourite colour. Because this information does not contain any sensitive information it is stored as a plain text cookie. The information on the form below is passed to the web server which stores it as a cookie with the name “favourite-colour”. The server then refreshes this page which reads the cookie and displays it below.
“favourite-colour” cookie does not exist.
} else {cookie name = favourite-colour
cookie value = @Model.FavoriteColor
}Try using a browser add-on to edit the cookie, then refresh the page. What happens?
In the example above the user can edit the cookie using a cookie add-on tool inside of the browser. There are cases where this can cause issues. For example the website may 4 taking an unauthenticated user (someone who is not logged in) through a survey that provides a bonus offer at the end. In this case it is advantageous to store the current survey page in a cookie, but we want the user to get through all of the pages of the survey. If the cookie is changed inside a cookie editor add-on, the user could potentially skip a few (or all) of the pages.
The solution is to utilize a hash function. A hash function can be though of as a one-way function. A string is passed to the hash which converts it to a unique fixed length string. It is not feasible to get the original string from just the of the hash function, however if both the input string and the returned hashed value are stored in a cookie, then upon read the two can be validated by entering the input string from the cookie into the value to check if it creates the same hash value that is stored in the cookie.
Enter your favourite number below, and it will be saved into a cookie along with it's hash. The page then refreshes and shows your favourite number if it can be verified. Which means the web sever is going to run the favourite number from the cookie into the hash function and compare it to the hash value also stored in the cookie. If the favourite number cannot be verified the server defaults to no favourite number. Try changing the favourite number in a cookie editor add-on and see what happens.
“favourite-number” cookie does not exist.
} else {cookie name = favourite-number
cookie value = @Model.FavoriteNumberCookieValue
favourite number = @Model.FavoriteNumber
hash value = @Model.FavoriteNumberCookieValue.Substring(Model.FavoriteNumber.Length + 1)
}Try using a browser add-on to edit the cookie, then refresh the page. What happens?
In the above example we have provided a means to verify that the value has not changed in the cookie by means of a hash. However, people are cleaver, and can try to create the same hash from an online service. Go to Xorbin and enter the same favourite number and compare it to the hash stored in the cookie. They are the same. This is because both use identical hash functions. Now enter a new favourite number at Xorbin and build your own cookie value in a text editor and paste it into this website's cookie. If you are careful you can fool the website. Not Good!
The work around for this is to add salt to the value before it enters the hash function. A salt is any random text that is added to the input string of the hash function. Remember a hash returns a consistent size string, regardless of the input size. For example, the server can have a secret salt of “foobar” and add this to the input value. It uses this same secret salt during the verification process. Since the salt is kept on the server, the intrepid hacker cannot create a new hash value.
“favourite-food” cookie does not exist.
} else {cookie name = favourite-food
cookie value = @Model.FavoriteFoodCookieValue
favourite food = @Model.FavoriteFood
hash value = @Model.FavoriteFoodCookieValue.Substring(Model.FavoriteFood.Length + 1)
}Try using a browser add-on to edit the cookie, then refresh the page. What happens? Even if you try to use a hash service without knowing what the salt used for the hashing function, it is unfeasible to determine the correct hash for a given favourite food value.
