RANK Window Function
The RANK window function determines the rank of a value in a group of values, based on the ORDER BY expression in the OVER clause. If the optional PARTITION BY clause is present, the rankings are reset for each group of rows. Rows with equal values for the ranking criteria receive the same rank. Amazon Redshift adds the number of tied rows to the tied rank to calculate the next rank and thus the ranks might not be consecutive numbers. For example, if two rows are ranked 1, the next rank is 3.
RANK differs from the DENSE_RANK Window Function in one respect: For DENSE_RANK, if two or more rows tie, there is no gap in the sequence of ranked values. For example, if two rows are ranked 1, the next rank is 2.
You can have ranking functions with different PARTITION BY and ORDER BY clauses in the same query.
Syntax
RANK () OVER ( [ PARTITION BY expr_list ] [ ORDER BY order_list ] )
Arguments
- ( )
-
The function takes no arguments, but the empty parentheses are required.
- OVER
-
The window clauses for the RANK function.
- PARTITION BY expr_list
-
Optional. One or more expressions that define the window.
- ORDER BY order_list
-
Optional. Defines the columns on which the ranking values are based. If no PARTITION BY is specified, ORDER BY uses the entire table. If ORDER BY is omitted, the return value is 1 for all rows.
If ORDER BY does not produce a unique ordering, the order of the rows is nondeterministic. For more information, see Unique Ordering of Data for Window Functions.
Return Type
INTEGER

Bride of Chucky * * (out of * * * * )
Directed by Ronny Yu. Cast: Jennifer Tilly, Katherine Heigl, Nick Stabile, John Ritter, Alexis Arquette, Kathy Najimy; voice of Brad Dourif. 1998 - 90 minutes. Rated R (for violence, gore, profanity, and doll sex). Reviewed October 17, 1998.
Although the original "Child's Play" was an intelligent, surprisingly well-crafted horror film, I have never been that big a fan of the series.  But old slasher series' die hard, and since there has been a recent horror resurgence, it was inevitable that Chucky would indeed be back for a third sequel.
"Bride of Chucky" has a genuinely goofy premise, and is far more original than the other sequels. The film starts off with Tiffany (Jennifer Tilly), a bit of trailer-park trash, who gets ahold of the remains of the mostly destroyed Chucky doll, which holds the soul of her old boyfriend, Charles Lee Ray. She sews the parts back together and resurrects Chucky who, in exchange, murders Tiffany and transports her soul into a female doll. They realize that in order to get out of the doll bodies, they have to get a necklace that Charles is buried with in a small town in New Jersey. Through a series of circumstances, these two murderous, feuding dolls hitch a ride with a teenage couple, Jude (Katherine Heigl) and Jesse (Nick Stabile), who have run away to be together. Did you follow all that?
"Bride of Chucky" has one of the most absurd plots of the year, and some sequences are downright silly (a sex scene involving the Chucky and Tiffany dolls immediately springs to mind), but I have to admit that I do admire the filmmakers for trying something a little bit different, rather than recycling the same exact storyline for each sequel. In fact, the film is basically a "Chucky" road movie, which is actually quite intriguing, but it never really follows through with its aspirations. Just as in the recent, "Halloween: H20," the movie felt much too short, as if there was a rush to get to the ending. If another ten to fifteen minutes had been added to the running time, it would have been much more satisfying.
I must honestly admit, however, that there is a lot to like in the film. For one, the screenplay is far more sharply written than the other sequels in the series, and there are a lot of clever in-jokes and sharp lines of dialogue. The beginning, for example, is set in a building where all of history's killers' remains are locked up, and before we get to Chucky, the camera passes by a hockey mask and the Michael Myers mask.
Another element I liked in the film is the realistic love-hate relationship between Chucky and Tiffany. Even though they are dolls, they act exactly like humans do, and are always fighting, but still love each other. They are some very funny exchanges between the two throughout, particularly a conversation where they discuss Martha Stewart.
For being a third sequel in a reputable slasher series, it is amazing some of the talent they were able to get. Director Ronny Yu is highly-acclaimed in China, and this is his American debut. Tilly is almost always a wonderful actress (and has even been nominated for an Academy Award), and she brings a lot of energy to the first act of the film, when she is in human form. The cinematography by Peter Pau is richly textured and well-done.
But if you look at "Bride of Chucky" as a horror film, which it is, that is where the film fails. There is so much zaniness in the story and dialogue that it is not the least bit scary or suspenseful (except for one scene involving Tilly and Alexis Arquette, as her gothic boyfriend). The movie also never takes off the way it should, and although it was surely on its way to getting to that next plateau, it never made it because it was simply too abrupt. If you are looking for a scary horror film during this Halloween season, then my recommendation would be to see "Urban Legend," which is far, far better. Although the filmmakers wanted "Bride of Chucky" to be more along the lines of recent genre-bending horror flicks, such as "Scream," what they basically have made is yet another 80's slasher film. You know, the type that usually wouldn't even get grandma's ticker going.

Hello there… My name is Melania Nur Fitriansa, you can call me mela, melan, or melani, whatever you want. I'm 18 years old. I’m studying as second years student in vocational school, program majoring in D3 Computer and Information System of Gadjah Mada University. My activities othen than studying is following one of Student Activity Unit in Universitas Gadjah Mada, that is Marching Band. In this activity, I learned to be able to manage time well, work hard, obey some rules, make decisions, on time, confident, and create solidarity.
I am also interested in photography and water sports, such as swimming and diving. I have been introduced to this sport when I was a child, as a proof, I have taken swimming lessons when I was 6 years old. Therefore I really like water spot. With my interest in photography and the water spot, I often photographed the scenery when I traveled to beaches, waterfalls, or beautiful rivers.
good time management
inner satisfaction

While PullApprove itself is focused on the human aspect of code review, you can integrate it with other automated static analysis checks and tests. This is often used in order to let machines do the boring, tedious work of verifying that code meets the style guidelines, passes test suites, is properly committed (signed-off-by), etc. before actually bothering real people on your team to look at PRs.
You can integrate with other services you're already using, or even build your own with tools like probot.
Other commit statuses can be referenced in group conditions or the overall pullapprove_conditions. For example, to prevent any human review from happening until your automated tests have passed, you could use a config like this:
{% code "yaml" %} version: 3 pullapprove_conditions: - "'license/cla' in statuses.succeeded" - "'*travis*' in statuses.succeeded" - "'codeclimate' in statuses.succeeded" groups: ... {% endcode %} {% endblock %}

| testEstimates {mitml} | R Documentation |
Computes final parameter estimates and inferences from multiply imputed data sets.
testEstimates(model, qhat, uhat, extra.pars = FALSE, df.com = NULL, ...)
model |
A list of fitted statistical models as produced by |
qhat |
A matrix or list containing the point estimates of the parameters for each imputed data set (see 'Details'). |
uhat |
An array, matrix, or list containing the variance estimates (i.e., squared standard errors) of the parameters for each imputed data set (see 'Details'). |
extra.pars |
A logical flag indicating if estimates of additional parameters (e.g., variance components) should be calculated. Default is |
df.com |
(optional) A numeric vector denoting the complete-data degrees of freedom for the hypothesis tests (see 'Details'). |
... |
Not used. |
This function calculates pooled parameter estimates and inferences as suggested by Rubin (1987, "Rubin's rules") for each parameter of the fitted model.
The parameters can either be extracted automatically from the fitted statistical models (model
) or provided manually as matrices, arrays, or lists (qhat
and uhat
, see 'Examples').
Rubin's original method assumes that the complete-data degrees of freedom are infinite, which is reasonable in larger samples.
Alternatively, the degrees of freedom can be adjusted for smaller samples by specifying df.com
(Barnard & Rubin, 1999).
The df.com
argument can either be a single number if the degrees of freedom are equal for all parameters being tested, or a numeric vector with one element per parameter.
Using the extra.pars
argument, pooled estimates for additional parameters can be requested (e.g., variance components).
This option is available for a number of models but may not provide estimates for all parameters in all model types.
In such a case, users may extract the estimates of additional parameters by hand and pool them with the qhat
argument (see 'Examples').
No inferences are calculated for pooled additional parameters.
Currently, the procedure supports automatic extraction of model parameters from models that define coef
and vcov
methods (e.g., lm
, glm
, lavaan
and others) as well as multilevel models estimated with lme4
or nlme
and GEEs estimated with geepack
.
The arguments qhat
and uhat
provide a general method for pooling parameter estimates regardless of model type (see 'Examples').
Support for further models may be added in future releases.
A list containing the pooled parameter and inferences.
A print
method is used for more readable output.

This guide will help you understand how to use Media Check Pro (MCP).
Installation
Extract the .zip folder and run 'Media Check Pro.exe'.
Graphical User Interface
After starting the program, you will be greeted with this window:
This is the main window that lets you perform the checks and conversions.
Checking Files
This section shows you how to check files.
Check Single File
To check a single file, click the Check Single File button (5). Doing this will open a windows dialogue that will let you select the file you want to check. Choose a file then click 'Open'. You will then be presented with a dialogue box similar to this:
If you click 'Yes' the check will start. If you click 'No' a message box will appear informing you the check has been cancelled. Click 'Ok' and you will be sent back to the main windows.
When the check has finished you will get a message saying either the check has completed successfully, or that the check completed with errors. With ether message pressing ok will return you to the main window.
If the check was successful you will see a window that looks like the one in Image 4 (GUI section). However, if the file has errors you will see a window that looks the one in Image 3 (GUI section).
The check is now complete.
Bulk Check Folder
To check a folder the process is very similar to checking a single file.
First, select the file type from the Original File Type menu (3). You can choose one of the pre-defined file types, or type your own in. If you select * (All Files) every file type will be checked, including none media files like pdf files and text documents. This will likely cause errors so use with caution.
Once you have selected the file type, click the Bulk Check Media Directory button (6). Doing this will open a windows dialogue that will let you select the folder you want to check. Choose a folder and then click 'Select Folder'. You will then be presented with a dialogue box similar to this:
If you click 'Yes' the check will start. If you click 'No' a message box will appear informing you the check has been cancelled. Click 'Ok' and you will be sent back to the main windows.
The folder you chose, along with all subfolders will be scanned for the media type you previously selected, then, each file that is found will be checked. If no files are found, you will receive this message:
Clicking 'Ok' will send you back to the main window.
When the check has finished you will get a message saying either the check has completed successfully, or that the check completed with errors. With ether message pressing ok will return you to the main window.
If the check was successful you will see a window that looks like the one in Image 4 (GUI section). However, if the file has errors you will see a window that looks the one in Image 3 (GUI section).
The check is now complete.
Converting Files
This section shows you how to convert files.
Convert Single File
To convert a single file, first select the file type you want to convert to from the New File Type drop-down list (4) once you have done that select the format/codec you want to use from the Conversion Options drop-down list (12). If you want to adjust the quality or other options, see the Advanced Options section.
Once you have selected your options click the Convert Single File button (7) doing this will open a windows dialogue that will let you select the file you want to convert. Choose a file then click 'Open'. You will then be presented with a dialogue box similar to this:
If you click 'Yes' the conversion will start. If you click 'No' a message box will appear informing you the conversion has been cancelled. Click 'Ok' and you will be sent back to the main windows.
During the conversion you will see a command prompt window appears, you do not need to interact with this window, it is just a display of what FFMPEG is doing.
When the check has finished you will get a message saying either the conversion has completed successfully, or that the conversion completed with errors. With ether message pressing ok will return you to the main window.
Bulk Convert Folder
To convert all files in a folder, you follow a similar process as converting a single file.
First, select the file type you want to search for from the Original File Type menu (3). You can choose one of the pre-defined file types, or type your own in. If you select * (All Files) every file type will be converted, including none media files like pdf files and text documents. This will likely cause errors so use with caution.
Next, select the file type you want to convert to from the New File Type drop-down list (4) once you have done that select the format/codec you want to use from the Conversion Options drop-down list (12). If you want to adjust the quality or other options, see the Advanced Options section.
Once you have selected your options click the Bulk Convert Media Directory button (8) doing this will open a windows dialogue that will let you select the folder you want to convert. Choose a folder and then click 'Select Folder'. You will then be presented with a dialogue box similar to this:
If you click 'Yes' the conversion will start. If you click 'No' a message box will appear informing you the conversion has been cancelled. Click 'Ok' and you will be sent back to the main windows.
The folder you chose, along with all subfolders will be scanned for the media type you previously selected, then, each file that is found will be converted. If no files are found, you will receive this message:
Clicking 'Ok' will send you back to the main window.
During the conversion you will see a command prompt window appears, you do not need to interact with this window, it is just a display of what FFMPEG is doing.
When the check has finished you will get a message saying either the conversion has completed successfully, or that the conversion completed with errors. With ether message pressing ok will return you to the main window.
Cancel Check or Conversion
The process for cancelling a check or conversion is the same. At any point simply click the 'Cancel' button (15) and MCP will safely cancel the check or conversion.
When the process has been stopped you will see a message like this:
Click 'Ok' and you will be taken back to the main window.
Check and Conversion Logs
During the checking and conversion process, log files are created. If there are no issues when dealing with your files these logs are deleted. However, if any errors are spotted the logs are kept.
When a check or conversion is completed you will see a window similar the one in Image 3 or 4 (GUI section). You will notice in Image 3, which is what happens when a check returns errors, there is a button that says 'Show Log' (16). This button opens a saved text file that lists all files that contained errors from the previous run of the program. This file is saved in the root of the directory you asked to search / the directory where the single file you selected is stored.
With the information in the log, you should be able to locate the problematic files. When you do, you will notice another log file with the same name next to each file in question. This contains the ffmpeg log that was captured during the check or conversion of the file. Letting you see in detail what was wrong with the file.
Advanced Options
Media Check Pro has some advanced options.
Error Levels - When checking files, you can choose the level of detail the check looks for, either Errors Only, or Errors and Warnings. This is done with the Check Level drop down (11). Errors only if the default and will only pick up things that would stop the video playing. Warnings will pick up anything that may be wrong with the video, even if it plays perfectly in your choice of video player you will most likely still get errors.
Conversion Options - As mentioned in the conversion sections you can choose from a range of conversion options with the drop-down list (12). When you select one you will notice the text in the FFMPEG CMDs box (13) change. This is the list of commands that will be run when converting. Before converting, you can change the text in the text box to adjust the conversion options. Whatever is typed in the box will be run. The commands are standard ffmpeg commands that would go in between the input and output flags when using ffmpeg in command prompt. See this page for details. https://ffmpeg.org/ffmpeg.html.
Clean Logs - When checking and converting files MCP creates some log files next to the original source file. After running MCP if you still see these it means the file had errors. As these files could build up MCP has a tool for cleaning them built in.
To run this tool go to the help menu (2) then click 'Clean Log Files'. You will then be presented with this window:
Click 'Choose Directory' and choose the folder you want to clean. WARNING this will remove all files with the extension '.log' or '.xmcpcheck'.
Once you have selected the folder you will be given a final confirmation window:
Clicking 'Yes' will clean the files, clicking 'Cancel' will top the process.
Once the process is complete you will see a message like this, informing you how many files have been deleted. Clicking 'Ok' will return you to the main window.
Errors
Although you might see MCP say a media file has errors, there is only one error the program itself can encounter.
On start-up, MCP looks for 'ffmpeg.exe' in the program folder. If this is not there you will see this message:
Under normal usage, you should never see this message. However, if you delete or rename 'ffmpeg.exe' this message will appear. This error can also occur if you force quit the application then start it back up. This is because during the checking and conversion process 'ffmpeg.exe' is temporarily renamed. If the application is forcefully terminated during this time the file may not revert back to its original name, causing the error.
If this occurs, look in the folder that contains 'Media Check Pro.exe'. If you see a file that has a similar name to '00000000-000000000_ffmpeg.exe' where the 0s can be any number, rename it to 'ffmpeg.exe' then restart the program. If you cannot find this file, go to https://ffmpeg.zeranoe.com/builds/ and download the latest 64bit static windows build. Then place 'ffmpeg.exe' in the Media Check Pro folder.

| Apache Struts 2 Documentation > Home > Guides > Contributors Guide > Building the Framework from Source > Building with Maven |
| Maven 2.0.4 or later is required to build Struts 2 |
First, let's review some Maven basics. Maven uses the notion of a build lifecycleto which plugins can attach. (Plugins are similar to Ant tasks.) When a Maven build is invoked, we specify a point in the lifecycle up to which the build should proceed. The phase compile comes before test, and test comes before package, and package comes before install. Once we have Maven setup, we can invoke the Struts build, and specify which phase the build should use.
The install phase builds up the project ("package"), and installs any JARs it needs into your local repository (e.g. ~/.m2/repository). Once installed, the JARs can be used by any other Maven project you build. The install phase is the default phase if none is specified.
To run a basic install, change to the root of the source distribution, and enter
> mvn
That's it! Maven will download all dependencies the build needs, run all unit tests, package up the JARs, and then install the new JARs locally. For your convenience, copies of the JARs can be found in the target directories of each module. For example, after the build, the main JAR can found at core/target/struts2-core-2.0-SNAPSHOT.jar.
| It's suppose to be automatic, but you might still have to press the button Sometimes, licensing restrictions prevent Maven for downloading all the JARs that a build might need. For example, JavaMail and Activation, can only be downloaded from Sun. When this happens, Maven will display a helpful message that explains how to install these JARs manually. After downloading the required JAR, follow the instructions to install it to the your local repository. Once installed, the JAR is availale to all your Maven builds, not just Struts. |

There are other phases that can be useful when working with Maven. The package phase will just JAR (or WAR) the modules. The test phase will run only the unit tests. The compile phase will only build the source code (but not the test sources). And the clean phase will remove all artifacts, typically the entire target directory.
The next step to building the framework with Maven is to understand build profiles. Profiles provide different configurations for a build. There are several profiles, including default, xwork, and _thirdparty".
| Profile | Description |
|---|---|
| default | Builds site, api, and core |
| apps | Builds the example applications |
| plugins | Builds all plugins |
| extras | Includes the extras module that cannot be part of the default build due to licensing incompatibilties |
| xwork | Includes the xwork build |
Tbe default profile will work for most developers, but some developers will want to use additional profiles as they work on both XWork and other modules, such as the JasperReports integration.
Specify a profile is as simple as:
> mvn -Pprofile ...
If you want to build all the extras module not included with the default build, use the _extras*_profile.
> mvn -Pextras
[INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] ------------------------------------------------------------------------ [INFO] Struts 2 ..............................................

In the second run, the Extras module is built. If you decide to make use of this module, be sure to review the licenses of its dependencies, since they may be under a license incompatible with the Apache License.
Struts 2 is an extension of the XWork framework. While Struts2 adds a lot of value for web developers, much of the core functionality derives from XWork. The xwork plugins add the capability to build against a current XWork checkout, rather than a precompiled JAR.
The plugin assumes that the latest XWork code is checked out and is located at ../xwork, relative to the struts2 folder. You can check out XWork using the Subversion command:
svn co https://svn.opensymphony.com/svn/xwork/trunk xwork
| Subversion If you don't have the command line version of Subversion installed, you can download it from the Subversion site, and add the bin folder to your command path. |
> mvn -Pxwork package
[INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] ------------------------------------------------------------------------ [INFO] XWork ................................................. SUCCESS [39.527s] [INFO] Struts 2 .............................................. SUCCESS [0.216s] [INFO] Struts 2 - Core ....................................... SUCCESS [29.736s] [INFO] Struts 2 API .......................................... SUCCESS [0.318s] [INFO] ------------------------------------------------------------------------ [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESSFUL [INFO] ------------------------------------------------------------------------ [INFO] Total time: 1 minute 11 seconds [INFO] Finished at: Wed Jul 19 10:57:27 PDT 2006 [INFO] Final Memory: 12M/53M [INFO] ------------------------------------------------------------------------
Now, Maven will build XWork from source and use that as the XWork snapshot for the Struts build.
Maven can build against multiple profiles. If you are developing against both the XWork and Struts 2 frameworks at once, you can install both profiles with one call to Maven.
> mvn -Pextras,plugins,xwork
Using both profiles is especially important when using Maven to build your IDE project files (recommended).
Maven has a great feature that will allow you to build up your IDEA or Eclipse project files based on the project build structure. Using the Maven project files helps keep developers in-sync and efficient. The IDEA project files are pre-configured to define in the Run/Debug menu many common tasks, such as "execute all tests", "launch the showcase sample app", and so fort.
The Maven IDEA plugin creates IDEA project and modules files, based on the Maven build configuraton (pom.xml).
First, be sure you have the latest IDEA plugin for Maven.
mvn -DconnectionUrl=scm:svn:http://svn.apache.org/repos/asf/maven/plugins/trunk/maven-idea-plugin \
-Dgoals=install \
scm:bootstrap
Most often, we use Maven to build projects, but it can also run plugins directly. To build an IDEA project file for Struts 2, including all the modules, run
> mvn idea:idea -Papps,extras,thirdparty,xwork
Maven will generate struts-parent.ipr, struts-parent.iws, and an iml file for each module listed Open up struts-parent.ipr in IDEA, and you should be good to go.
If you ever need to rebuild your projects, running the idea:idea command again will update your files without overriding any information that doesn't conflict. If you do want to overwrite the project files, specify the overwrite parameter as true.
> mvn idea:idea -Doverwrite=true -Papps,extras,thirdparty,plugins,xwork If you only need to rebuild some of the modules, adjust the list of "profiles".
| Clearing the cache If you find the xwork module causing you problems, such as displaying as "XWork" when it should be named "xwork", the problem is likely to be within IDEA. Try clearing out your IDEA system cache and then run it again |
For Eclipse, try
> mvn -Pthirdparty,plugins,xwork eclipse:eclipse
| Feedback Wanted Many Struts 2 developers use IDEA, and the Eclipse project files are not as well-tested or featureful as the IDEA versions. But as far as we know, they work! |
Currently the sample applications can be deployed using the Maven 2 Jetty plugin. For example, you can run the showcase example application from the command line:
cd apps/showcase mvn jetty:run
You could also use one of the Maven IDE plugins to run the plugin or simply execute the mvn or mvn.bat file as an external application within your IDE.
A few helpful tips for using Maven are provided:
If you are disconnected from the Internet or simply wish to make your build faster, pass in the -o argument and Maven won't check for new modules to download.
mvn -o -Pextras,plugins,xwork
If you get an OutOfMemoryError while running the tests:
// Bash export MAVEN_OPTS=-Xmx512m // Windows set MAVEN_OPTS=-Xmx512m
Although this shouldn't ever happen, sometimes tests do fail and you need to build the framework anyway. If there's a problem, you can pass in the skip tests parameter.
mvn -Dmaven.test.skip=true -Pextras,plugins,xwork
Of course, if you find tests are failing, please submit a patch to fix them!
Struts 2 depends on the current snapshot artifact of XWork 2. Unfortunately, if XWork 2 is modified in a significant way, the Struts build doesn't check for and retrieve a new version of the XWork snapshot jar, resulting in compilation or unit test failures.
The solution is to clear out any stale XWork 2 jars in your local Maven repository, usually by removing the directory ~/.m2/repository/opensymphony. This will force the Struts Maven build to pull down a fresh copy of XWork and hopefully resolve your problem.
Maven terms a release build an "assembly". An assembly aggregates the builds of all the modules installed locally on your machine into one or more release files.
To create a release, you must first build and install locally every artifact. From the root struts2 directory, run:
mvn -Pextras,apps,plugins install
Next, you need to run the assembly build to create the release files. From the struts2/assembly directory, run:
mvn assembly:assembly
If the assembly built correctly, you should see the release files in the target/assembly/out directory.
The default mirror for Maven builds ("ibiblio") can be slow and unreliable. Maven lets you specify alternative mirrors so that you don't have to depend on ibiblio for everything.
You can add new mirrors through the Settings file (~/.m2/settings.xml).
<settings> <mirrors> <mirror> <id>dotsrc</id> <url>http://mirrors.dotsrc.org/maven2</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> </settings>
| Sometimes the alternative mirrors have problems too or aren't updated at the same frequency as the main mirror. If you have trouble building, try commenting out the aternative mirror. |
In some cases it has been seen that Maven will complain a module doesn't exist, even though it is part of the current build. Often, the missing module complete turins up when executing {mvn package}}. A simple fix for this is to run mvn install instead. If you have to do this, it will probably only be a one-time thing.

Automated realtime fare evasion detection system can help save million of dollars for transit authorities.
This project proposes a video analytic pipeline for action recognition, it won developer choice award in
Deep Learning Superhero Challenge, Intel.
This system does the following:
Over-reliance on supervised image tasks leaves us with a dependence on large
volumes of human-labeled data, a luxury that is not available across all domains.
In contrast, it is comparatively easy to accumulate a large dataset of unlabeled
images. Consequently, to use the unlabeled datasets, it is vital to learn mean-
ingful representation through unsupervised training. In this study, we evaluate
unsupervised training methodologies by analyzing their efficacy in a downstream
image classification task with limited labeled data. We find that RotNet based pre-
training outperformed the fully supervised benchmark on our labeled data, which
emphasizes the utility of representations that unsupervised training can learn. We
also perform an elementary exploration of variational autoencoders and a siamese
regularized variational autoencoders, a variant introduced by us.

In machine learning projects we often run into curse of dimensionality problem where the number of records of data are not a substantial factor of the number of features. This often leads to a problems since it means training a lot of parameters using a scarce data set, which can easily lead to overfitting and poor generalization. High dimensionality also means very large training times. So, dimensionality reduction techniques are commonly used to address these issues. It is often true that despite residing in high dimensional space, feature space has a low dimensional structure.
Two very common ways of reducing the dimensionality of the feature space are PCA and auto-encoders.

Lipstick on a Pig introduces a new definition of bias,
bias my neighbourhood of other biased words, and shows that it correlated with bias
by projection on gender subspace(earlier definition) proposed by Bolukbasi.
It shows that as seen by this new metric bias is not removed and female biased words
cluster with other female biased words and vice versa.
Hence current debiasing techniques which use the earlier definiton are insufficient.
Since the code of this paper is not provided I reproduced the results in the paper for GloVe
and Gn-GloVe embeddings.

When trained on public data sources the language model can also learn the biases of the society.
I wanted to explore a simple way of auditing a language model for racism.
Neural Language Models are an important part of virtual speech based assistants.
Once trained, it can assign a calculate which sentences are more likely to be
uttered by assigning probabilities to them. I trained a Language Model on publicly available
news data and performed a racial audit using a simple technique.
Dataset I used consisted of news articles that had word crime in the heading.

Happy Birthday Golu!
Life is beautiful due to your existence :)
There are thousands of things to say and infinite more to experience with you. Cheers to this life and another great year with you!!

Just remembering everything and being high on the happiness I share with you. Miss you!
Some Childhood memories
Cuteness and innocence as has been youu golu!  Your writing and your words have the power to make ships turn around and people to reach for the sky. Emotions expressed so poignantly that the reader gains a vicarious experience, much like the writer himself. You have the power to give vision to the unaware and glasses to the visionaries as well...
This is a rare trait of observation and distillation you have developed...want to see you write more :)


One week ago, my co-founder and I found ourselves staring down a thick stack of paper UI prototypes; almost 50 pages total. One week before that, we threw out a perfectly good, working beta product because customer feedback suggested a significantly better path. The tale of how we ended up at that point is entertaining as well, but it will have to wait for another time. This is the tale of how our paper prototype turned a pair of long time Python developers (and documented framework haters) into Ruby on Rails developers.
Paper prototyping proved to be an extremely worthwhile exercise, but we really wanted something we could click around. We devised a strategy to build a clickable prototype that would evolve into production code. The plan was to stub out all of the views with static HTML and CSS. The CSS could be directly carried over to the product and the HTML could be retrofitted as templates. Having become religious about Sass about a year ago, I fired up the file watcher (which automatically rebuilds CSS) and set to work filling a directory with sass and html files.
After some time, I asked myself “I wonder if Haml
has a --watch
argument?” (it doesn’t) because Sass
makes me hate Html’s verbosity. Armed with
practically zero Ruby knowledge, I hobbled together a simple
Rakefile
and Haml watcher script and got back to work.
“Neat”, I said and thought nothing of it.
Then we designed our URLs in an indented plain text file, which pretty much directly mapped into the routes.rb file and some trivial (empty method) controllers. Whoops! Now we’re writing Ruby.
“At this point, we might as well try Rails proper.”
Generated some models and corresponding migrations: “Wow, explicit schema with reflective model objects. None of this declarative schema bullshit.”
Wired up some controllers. “The structured params infrastructure is pretty cool.”
“Ruby is kinda fun. Blocks are super useful.”
Integrated Authlogic. “Wow, that was easy. I really like how it does not force any front-end decisions on me.”
“Rails is full of evil black magic that I do not understand, but it seems to read my mind, so I don’t really care.”
Started to apply some polish and work on the 10% that takes 90% of the time. “I think I can safely add Ruby to my resume now.”
Late at night, at the very end of the week, exhausted, we stared at each other. “Dude, I think we can show this off to people tomorrow.” Walking out the door of the office, my co-founder said to me “I feel so dumb for having ignored Rails for so long. I just assumed it was Ruby’s Django”.
We accidentally implemented our entire beta product in one week, with zero prior Ruby or Rails experience.
When I have some more time (and experience), I’ll try to write about specific design decisions that set Rails apart.

Great story! I love the black magic quote – but I think it will feel more apropos when you use rspec as a test framework.
Joe Lallouz
Sweet. A very similar situation happened when my co-founder and i switched to Groovy and Grails.
Dan
How did I never notice you on Hacker News before? I read it every day!
Andrew Ingram
Weird, I moved to Django because I was fed up with building sites using Rails :p
I guess everyone has their own preferred style.
Eric Floehr
The best language for you is the one in which you are most productive in, so awesome!
My first public website was in Rails, and I assumed Django was just Python’s Rails.
I have since converted it to Django because Django allows me to be more productive, and ActiveRecord didn’t work well for me.
Best of luck, and congrats again for finding such productivity!

Max
Did you give web2py a try? I believe it provides in Python what you found in Rails.
JonnieCache
“lol, do you always call your co-founder a bastard?” I’m guessing he’s in the UK :)
Brandon Bloom
@Dan: I haven’t been hiding :–)
@Andrew: I think that’s why these topics are such hot issues. It is more preference and religion than anything else. Django is a solid piece of code and a stellar community, but it just doesn’t mesh with my brain.
 I consider that a complement. And no, I’m not from the UK. I’m from NY, he’s from Philly, and we are currently located in Seattle.
@Max: I’ve played with web2py, but wasn’t super impressed. But hey, I thought the same thing about Rails. I guess you need to really try to make something to understand. What about it is interesting in particular?
Nicko
Just out of interest, which version of rails are you using?
Brandon Bloom
Rails 3
Psylinse
And here I am going from Rails (because of black magic :) to Pylons, which took a lot from Rails, but its in Python!
Perhaps you should give Pylons a look over, just some food for thought.

I originally began programming in Python with Django myself, but I saw Rails and immediately went.. WTF!? to Django and Python in general.
fitzgeraldsteele
I think the real lesson here is to find the right tool for the right job. Both Rails and Django are pretty strong pieces of framework, allowing you to do a lot in a little amount of time.
I had a similar experience, where I quickly prototyped a website in Rails. I showed it off and said, “see…this is pretty much done.” And then developers on my team felt the need to rebuild the site in PHP since that’s what our company ‘officially supports.’ :)
On another project, I was able to quickly use the Django ORM to introspect an existing MySQL database, and build an admin interface for some of our internal users. That was a HUGE win for me to be able to quickly make the admin site.
So, the right tool for the right job…
Max
@Brandon
Given your article I thought your would like the fact that in web2py everything has a default. For example is you just type:
|
web2py creates the table (if it does not exist, or alters it as necessary), a web based database administrative interface, and crud.create, crud.update, crud.read, crud.select, crud.search forms that you can insert in your app like
|
It also includes role based access control out of the box with pluggable authentication mechanisms.
Web2py also has a component/plugin architecture that is best described by this video http://vimeo.com/13485916
Since you are coming from Python, I though you may be interested. Anyway, I too really like Rails and web2py was originally designed to be in Python but closer to Rails than other Python frameworks.
brokenladder
Semantic indenting is far and away the best thing about Python, and Haml/Sass prove Ruby should adopt it too.
Brandon Bloom
@brokenladder: Hell yes.
coulix
Well in my case I am way more productive in Python, especially when prototyping with Django. It all depends on the mastering level of the tool. One point I will give to rails is haml tho. We need a proper equivalent well integrated in Django/Python.
Rafael Rosa Fu
Hi,
Next time you need to authentication, try Devise instead of Authlogic, and check Ruby Toolbox for more interesting Ruby tools.

Could you expand on your file watcher script? Running a background process (e.g. re-compile) on change is a common pattern that I haven’t found a tidy solution to…
 Each had their pros and cons.
Steve has a simple Python script here: http://stevekrenzel.com/articles/autoreload
However, in this case I used FSSM: http://github.com/ttilley/fssm
FSSM has the advantage that it uses the platform’s native file notification mechanism, so it tends to respond more quickly (no polling delay).
T T
Awesome post! I’ve been comfortable with Django though I am dabbling into Rails but I’m having trouble with getting to grips with Ruby. Would you recommend anything you’ve read that allowed you build a working prototype? I’m curious about how you managed to learn it so quickly. Thanks!
Brandon Bloom
@TT: I took advantage of the fact that many people switch to or from Python. I searched for phrases like “python’s foo in ruby”. Ruby is so similar to Python, it was pretty easy to just pretend it’s the same and go back for cleanup as you learn the idiomatic approaches.
Also, I generally just have an interest in programming languages. I’m pretty fluent with about a half dozen languages, so each marginal new language is that much easier to pick up.
As an aside: the “end” keyword is just sooo unnecessary!

This determines how key presses and releases are pre-processed, after the keyboard splitting but before the main or {_link_program link} {_instrument instruments} and MIDI output.
There are three polyphonic modes:
| polyphonic | For normal polyphonic playing. {_glide Glide} is normally disabled, but if the {Common_footswitch_mode} parameter assigns the left footswitch to the "glide" function, it can be conditionally enabled, although it effectively switches to mono single mode (see below) while it is enabled. This is the default. | |
| poly ordered | Whenever a new chord is played, the notes are assigned to voices in pitch order, from top to bottom, so that the voices will remain in the same pitch order when gliding from one chord to another. This involves delaying by an amount specified by the {_global_parameter global} rollover time parameter, to make sure the entire chord has been captured. | |
| poly buffered | Notes are not directly played, but are added to a buffer, and then played in pitch order, from top to bottom, when the left footswitch is pressed (irrespective of the footswitch mode parameter). The buffer is cleared whenever the number of held keys goes from zero to one. |
There are five monophonic modes:
| single | Only one note is played at a time, and new notes reuse the same voice(s). New notes only retrigger the envelopes if no note was already held. | |
| multiple | Only one note is played at a time, and new notes reuse the same voice(s). New notes always only retrigger the envelopes. | |
| first | Only one note is played at a time, and only if no notes were previously held. | |
| bottom | Only one note is played at a time, and only the bottom note if a chord is played. When playing an ascending scale, new notes are only played if there is a gap between them, or at least less overlap than the time specified by the global rollover time parameter. | |
| top | Only one note is played at a time, and only the top note if a chord is played. When playing a descending scale, new notes are only played if there is a gap between them, or at least less overlap than the time specified by the global rollover time parameter. |
There are four arpeggiation modes, which involve repeated playing of buffered notes. The buffer is cleared whenever the number of held keys goes from zero to one. The arpeggiation continues as long as at least one key is held, or the sustain footswitch is held. Once all keys are released, releasing and pressing sustain can stop and restart the arpeggio. The patterns are:
| up | Ascending pitch order. | |
| down | Descending pitch order. | |
| up/down | Bidirectional, starting on the bottom note. | |
| down/up | Bidirectional, starting on the top note. |
There are two sequence modes, which are similar to the arpeggiation modes except that they keep notes in the order they were played, rather than pitch order. This means that the same note can be added to the buffer more than once. The patterns are:
| sequence | In order of playing. | |
| random | In random order. Notes that have multiple copies in the buffer are played more often. |
There are two strum modes. In this mode, the lowest or highest two notes of the keyboard are filtered out even before the keyboard split takes place, and used as triggers. They cause any other notes held on the keyboard to be replayed. Held notes are also added to a buffer, which isn't cleared until the next time the number of held notes goes from zero to one, and the trigger plays all released notes that are still in the buffer but with a very short duration, simulating strumming on damped strings. (The apparent duration of the short notes can be adjusted via its envelope release parameters.)
| strum low | The lowest two keys are used as the triggers. | |
| strum high | The highest two keys are used as the triggers. |
If using the strum modes with an external keyboard, you should play the lowest and highest note of the keyboard once before the performance, so that the Digital Chroma will know the range of the keyboard. This isn't necessary on the internal keyboard.
These are presented in the {Common_controllers_cluster controllers cluster} within the {Common_section}.
This is contained in the CONTROL section of the right panel, under the following parameter number:

Constructing Roads
问题描述 :
There are N villages, which are numbered from 1 to N, and you should build some roads such that every two villages can connect to each other. We say two village A and B are connected, if and only if there is a road between A and B, or there exists a village C such that there is a road between A and C, and C and B are connected.
We know that there are already some roads between some villages and your job is the build some roads such that all the villages are connect and the length of all the roads built is minimum.
输入:
The first line is an integer N (3 <= N <= 100), which is the number of villages. Then come N lines, the i-th of which contains N integers, and the j-th of these N integers is the distance (the distance should be an integer within [1, 1000]) between village i and village j.
Then there is an integer Q (0 <= Q <= N * (N + 1) / 2). Then come Q lines, each line contains two integers a and b (1 <= a < b <= N), which means the road between village a and village b has been built.
输出:
You should output a line contains an integer, which is the length of all the roads to be built such that all the villages are connected, and this value is minimum.

正在练习，很有帮助
这个问题别太纠结了，不同的编译器结果不一
a是根先忽略掉，递归子树。剩下前缀bejkcfghid和后缀jkebfghicd，分拆的原则的是每个子树前缀和后缀的节点个数是一样的，根节点出现在前缀的第一个，后缀的最后一个。根节点b出现后缀的第四个位置，则第一部分为四个节点，前缀bejk，后缀jkeb，剩下的c出现在后缀的倒数第2个，就划分为cfghi和 fghic，第3部分就为c、c
