Allow to define a template for data formatting/parsing.
A template contains substitutions and delimieters.
Each substitution specifies data escaping rule:
Quoted, Escaped, CSV, JSON, XML, Raw.
Website ${domain:Quoted} has ${count:Raw} pageviews.
You can specify a template for rows, a delimiter between rows
and a template to wrap resultset.
Example: to parse web access logs.
Example: to parse deeply nested JSON.
Example: generate HTML right in ClickHouse.

Example: store hot data on SSD and archive data on HDDs.
Multiple storage policies can be configured and used on per-table basis.
Step 1: configure available disks (storage paths):
<disks>
<fast_disk> <!-- disk name -->
<path>/mnt/fast_ssd/clickhouse</path>
</fast_disk>
<disk1>
<path>/mnt/hdd1/clickhouse</path>
<keep_free_space_bytes>10485760
</keep_free_space_bytes>
</disk1>
...
Step 2: configure storage policies:
<policies>
<ssd_and_hdd>
<volumes>
<hot>
<disk>fast_ssd</disk>
<max_data_part_size_bytes>1073741824
</max_data_part_size_bytes>
</hot>
<cold>
<disk>disk1</disk>
</cold>
<move_factor>0.2</move_factor>
</volumes>
</ssd_and_hdd>
...
Step 3: use the configured policy for your table:
CREATE TABLE table
(
...
)
ENGINE = MergeTree
ORDER BY ...
SETTINGS storage_policy = 'ssd_and_hdd'
The data will be moved between volumes automatically.
You can also do it manually:
ALTER TABLE table
MOVE PART|PARTITION ...
TO VOLUME|DISK ...
— available in 19.15 testing.
For data transformation at INSERT time:
INSERT INTO table
SELECT *, domain(URL)
FROM input(TSV, 'URL String, ...')
You pipe your data to this query as with usual INSERT.
Data is transformed on the fly by SELECT expression.
Examples:
— calculate data for columns;
— skip unneeded columns;
— do filtering, aggregations, joins.
— available in 19.15 testing.
Automatically tune index granularity if you have fat columns.
Everything is working out of the box.
— available in 19.13.

In Nepal, thousands of young people depart Kathmandu every day on flights to the Gulf Countries and Malaysia, where they make do with limited resources, squalid conditions, and the little knowledge they can glean from Internet and social media sources available on their mobile phones. The Asia Foundation's Safe Migration App, called Shuvayatra ("Safe Travels"), offers access to Nepali networks and multimedia content that can help migrants prepare for the experience in host countries both before and during their time abroad.
Through the app, users can find relevant, local-language content developed specifically for Nepali migrants, including extensive written materials, a news feed, audio clips and podcasts, and answers to common questions. Migrants can also use the app’s social media features to share information online.
We’ve put years of research into the needs of Nepali migrant workers and partnered with some of the most experienced local organizations in Nepal focused on the migration issue. This is how we work. By partnering with local organizations that already possess extensive knowledge and networks, our technical solutions can connect younger, less experienced workers to a global Nepali diaspora who can help new migrants manage a safer journey.


Plugin Information |

View Changes since last successful build on the plugin site for more information. |
This plugin adds a build action to aggregate changes from all previous builds to the last successful one. The primary goal is to generate a changelog to be used for continuous delivery, as an aggregate for all changes since the last deployable artifact.
Additionally, this plugin can be used to generate a changelog for an arbitrary range of builds :
- /changes-since-last-success/lastSuccess for the last successful build
- /changes-since-last-success/lastStable for the last stable build
- /changes-since-last-success/buildNumber/1234 for changes since build 1234
- /changes-since-last-success/since/date for changes since specified date (using yyyy-MM-dd'T'HH:mm:ss'Z')
Changelog
0.5
- Fix "last successful/stable build" computation to compute from current build, not absolute project last success/stable
0.4
- Change internal design for better flexibility
- expose aggregated changes as REST API
0.3
- fix date range computation
- include range definition in changelog header
0.2
- add "since" range definition to lookup per date
0.1
- initial release.


Court stops withdrawal of criminal charges against lawmaker-elect
Osagie Otabor, Benin
An Edo State High Court, Criminal Division has stopped an attempt by the Nigeria Police to withdraw criminal charges against the member-elect for Ovia North East I Constituency, Mr. Dunez Onaiwu Ugiagbe.
Mr. Ugiagbe is among the 14 members-elect that are yet to the inaugurated and have since relocated to Abuja.
Ugiagbe was earlier arraigned in absentia on six count charge bothering on forgery and impersonation.
He and others at large were said to have committed the offence around 2001.
Justice Ohimai Ovbiagele had at the last sitting issued a warrant of arrest against Ugiagbe.
At the resumed hearing of the case, Barr. B Omosun, a Superintendent of Police representing the CP Legal, Abuja told the court that the Police Act empowered the Police with investigation of Criminal cases.
Barr. Omosun sought to withdraw the charges already in Court to complete their investigation upon receiving a petition from the suspect.
But Solicitor General of the State, Barr. Oluwole Iyamu, urged the court to disregard the application saying it was a sad development that the Nigerian Police could reduce itself to the absurd level or wanting to deliberately truncate a case it is handling.
Iyamu said the state complied with section 216 of the criminal code to take over the case to ensure proper dispensation justice.
READ ALSO: Obaseki pledges support for Edo judiciary
He urged the Judge to discountenance the appearance of the Barr. Omosun and subsequently strike out the motion.
Justice Ovbiagele ruled that the appearance of Barr. Omosun be voided and therefore struck out his motion.
The State Counsel then proceeded to amend the charges previously filed by the Nigerian Police though a motion filed on November 14, 2019.
Barr. Paul Osarenkhoe, Counsel to Dumez UGIAGBE objected to the amendment which was overruled by the Judge.
In his ruling Justice Ovbiagele ruled that the state counsel reserve the right to amend charges at any stage of the proceeding.
He also ruled that the Bench Warrant served on Dumez Ugiagbe still subsist.
The case was adjourned to December 17, 2019 for hearing.

The stack also includes an early version (free while in Alpha) of the Basebot manager - a graphical interface for managing simple Q&A style responses without the need for code.
The deployment is provided as an easy to deploy CloudFormation template that will have you up and running in a matter of minutes.
Note: While this configuration has been extensively tested this stack is provides "as-is". Issues should be raised via the main Basebot Issue page.
Pre-requisites
Before deploying the template there are a number of pre-requisites that need to be met along with some additional information you will required to provide.
- An AWS Account with AWS Administrator privileges.
- An SSL certificate that has either been created in or imported to AWS Certificate manager in the region the template is to be deployed.
- A CIDR range for the VPC which will then be split into 4 subnets, ANS recommend this should be a /24, but can support CIDR address space that support a greater number of IP Addresses than a /24.
Architecture
The above template will deploy a standardised AWS infrastructure to host the BaseBot core and manager Docker containers and has been designed to provide both resiliency and security, whilst utilising services that keep operational tasks to a minimum.
The design utilises AWS Fargate to provide a managed compute service that hosts the BaseBot Server Docker containers, persistent and stateful information is stored in DynamoDB tables, AWS ELBv2 (Application Load balancer) is used to make the bot server available to Bot clients on the internet. Amazon LEX is integrated into the Bot server to provide AI based Natural Language Processing.


Kano elders to meet Fashola over bad state of Kano-Gwarzo-Dayi road
by Agency ReportWorried by the deteriorating state of Kano-Gwarzo-Dayi road which links Kano to four states, communities in the area have resolved to send a special delegation to meet with the Minister of Works, Babatunde Fashola, to elicit government action.
“We are formally going to lodge a complainant on the deplorable condition of the Kano-Gwarzo-Dayi road, which has become a death trap,” the member representing Gwarzo constituency, Yunusa Haruna-Kauyu, told the News Agency of Nigeria in Kano on Friday.
He said the delegation will comprise the Kano State Commissioner of Works, Muazu Magaji; the Senator representing Kano North senatorial zone, Sen. Barau Jibrin-Maliya; and members of the House of Representatives from the zone, among others.
“It is necessary to meet the minister in order to express the concerns of our people on the deteriorating condition of the road.

“It is a very important road which links Kano with four other states and Niger Republic.
“The potholes along the road had witnessed a number of patches, but even the potholes that were patched last year have already gone off.
“What this road requires now is total rehabilitation not patching of potholes.
“So we want the Federal Government to look at the possibility of awarding contract for the total rehabilitation of the road,” Haruna-Kauyu said.
NAN reports that the Kano-Gwarzo-Dayi road is a major link to Katsina, Sokoto, Zamfara and Kebbi states, as well as parts of Niger Republic.
The road was constructed during the administration of military President, Gen. Ibrahim Babangida and had never witnessed any major rehabilitation since then.
The lawmaker said that the total rehabilitation of the road would boost social and economic activities across the four states and beyond.

[gecode-users] Watching Propagators

First of all, just as was the case two years ago, nobody knows how to do
explanations for general propagators. The most interesting system for doing
explanations in a CP-like system at the moment is the lazy clause generation
research being done in the G12 project, where propagation is represented as
a SAT problem. This requires a completely different system and propagator
implementation though.
Remember, propagators in a CP system contain advanced algorithms that come
from many different fields of computer science (graph algorithms, numerics,
scheduling algorithms, ...), operating on variables that may have billions
of values. This is in contrast with SAT solving, where there is just a
single propagation rule over the simplest possible variable that needs to be
explained, and the propagation rule is in itself very simple.
What one could do without re-implementing all propagators is to simply
record all variables state before and after a propagator runs, and use that
as an explanation. Such a recording would in most cases be huge (making
anything but the simplest possible problem infeasible), and also would most
likely not be very useful. It simply doesn't say anything useful: it is very
common for many propagators to cover a large portion of the variables, and
many times not all the variables are relevant to the results. Also, it would
not suffice to just look at the most recently modified variables when a
propagator is run, the propagation performed might depend on all the
variables.
As a practical note, adding the kind of bookkeeping that you describe would
add quite a lot of overhead in many cases. As a comparison, simple
propagators for constraints such as <, !=, and so on take on the order of
ten to twenty machine instructions to execute in Gecode last time I
checked.
What is not clear to me is how you would like to use a hypothetical reason
that you would like to extract. Maybe there is something simpler that could
be used?
Cheers,
Mikael

java.lang.Object org.omg.CORBA.Request
public abstract class Request
An object containing the information necessary for invoking a method. This class is the cornerstone of the ORB Dynamic Invocation Interface (DII), which allows dynamic creation and invocation of requests. A server cannot tell the difference between a client invocation using a client stub and a request using the DII.
A Request
object consists of:
NVList
containing arguments for the operation.NamedValue
object, which has three
parts:
Any
object)
Request
objects may also contain additional information,
depending on how an operation was defined in the original IDL
interface definition. For example, where appropriate, they may contain
a NamedValue
object to hold the return value or exception,
a context, a list of possible exceptions, and a list of
context strings that need to be resolved.
New Request
objects are created using one of the
create_request
methods in the Object
class.
In other words, a create_request
method is performed on the
object which is to be invoked.

Todos
I originally implemented all filtering via Angular. This is the page with all that Angular filtering and no serverside filtering. I have some tests for combinations of things, but not as many as I would have wanted if I had more time/a partner. Additionally, I didn't have time for any CSS stuff to make the cut, but I tried many different methods for highlighting words on each todo card based on input parameters. Never figured that one out. Also, the radio button status filtering does not work. I think I got close to figuring that out but I need to sleep and work on any class but this one. To filter by status, the "Filter by status" field must have the values "complete" or "incomplete" typed out (case insensitive).
I like to think of this page as what an admin would see. An average user wouldn't see everyone's todos. The Fry page, on the other hand, is a more realistic user interface for the average end user.
{{todo._id}} ({{todo.owner}})Owner: {{todo.owner}}Status: {{todo.status}}Body: {{todo.body}}Category: {{todo.category}}
There was a problem loading the todos. Possibly the server is down or perhaps there are network
issues.
Please wait a bit and try again or start the server.


Because JE replication causes a current copy of your environment to be available at every data node in the group, the need for frequent backups is greatly reduced. Basically, every time a change is made on the Master, that change is backed up to every Replica node currently running. The result is that for each write operation you get a real-time incremental backup to n-1 nodes, where n are the total number of data nodes (including the Master) currently running in your replication group.
For this reason, JE does not currently support formal incremental backups of replicated environments. An application based upon the DbBackup utility class can be written to allow administrators to create full backups. This is useful for creating a backup to be stored on offline media, if your data strategy calls for that level of protection.
Remember that when performing a full backup, you should obtain the backup from a node that is current.
Note that DbBackup has some functionality that is specifically useful for replicated environments. See Backing up a Replicated Application for details.

This document proposes a mechanism by which an application APP can opt-in to exposing certain information with another application CAPTR, if CAPTR is screen-capturing the tab in which APP is running.
Consider a web-application, running in one tab, which we’ll name "main_app." Assume main_app calls getDisplayMedia and the user chooses to share another tab, where an application is running which we’ll call "captured_app."
Note that:
Both these traits are desirable for the general case, but there exist legitimate use cases where the browser would want to allow applications to opt-in to bridging that gap and enable a connection.
We wish to enable the legitimate use cases while keeping the general case as it was before.
Consider two applications that wish to cooperate, for example a VC app and a presentation app. Assume the user is in a VC session. The user starts sharing a presentation. Both applications are interested in letting the VC app discover that it is capturing a slides session, which application, and even which session, so that the VC application will be able to expose controls to the user for flipping through slides. When the user clicks those controls, the VC app will be able to send messages to the presentation app (either through a service worker or through a shared back-end infrastructure). These messages will instruct the presentation app to flip through slides, enter/leave presentation-mode, etc.
Capturing applications often wish to gather statistics over what applications their users tend to capture. For example, VC applications would like to know how often their users share presentation applications from specific providers, Wikipedia, CNN, etc. Gathering such information can be used to improve service for the users by introducing new collaborations, such as the one described above.
Users sometimes choose to share the wrong tab. Sometimes they switch to sharing the wrong tab by clicking the share-this-tab-instead button by mistake. A benevolent application could try to protect the user by presenting an in-app dialog for re-confirmation, if they believe that the user may have made a mistake.
This use-case is a sub-case of #3, but deserves its own section due to its importance. The "Hall of Mirrors" effect occurs when users choose to share the tab in which the VC call takes place. When detecting self-capture, a VC application can avoid displaying the captured stream back to the user, thereby avoiding the dreaded effect.
The capture-handle mechanism consists of two main parts - one on the captured side, one on the capturing side.
Applications are allowed to expose information to capturing applications. They would typically do so before knowing if they even are captured. The mechanism used is calling {{MediaDevices/setCaptureHandleConfig}} with an appropriate {{CaptureHandleConfig}}.
The CaptureHandleConfig dictionary is used to instruct the user agent what information the captured application intends to expose, and to which applications it is willing to expose said information.
dictionary CaptureHandleConfig { boolean exposeOrigin = false; DOMString handle = ""; sequence<DOMString> permittedOrigins = []; };
If false
, the user agent MUST NOT expose the captured application's origin.
The user agent MUST expose this value as {{CaptureHandle/handle}}.
Note: Values to this field are limited to 1024 16-bit characters. This limitation is specified further in {{MediaDevices/setCaptureHandleConfig}}.
Legal values of this field include:
"*"
If {{CaptureHandleConfig/permittedOrigins}} consists of the single item
"*"
, then the {{CaptureHandle}} is observable by all
capturers. Otherwise, {{CaptureHandle}} is [=observable=] only to capturers whose
origin is lists in {{CaptureHandleConfig/permittedOrigins}}.
{{MediaDevices}} is extended with a method - {{MediaDevices/setCaptureHandleConfig}} - which accepts a {{CaptureHandleConfig}} object. By calling this method, an application informs the user agent which information it permits capturing applications to observe.
partial interface MediaDevices { undefined setCaptureHandleConfig(optional CaptureHandleConfig config = {}); };
The user agent MUST run the following validations:
If all validations passed, the user agent MUST accept the new config. The user agent MUST forget any previous call to {{MediaDevices/setCaptureHandleConfig}}; from now on, the application's {{CaptureHandleConfig}} is config.
The [=observable=] {{CaptureHandle}} is re-evaluated for all capturing applications.
Capturing applications who are permitted to [=observable|observe=] a track's {{CaptureHandle}} have two ways of reading it.
The user agent exposes information about the captured application to the capturing application through the {{CaptureHandle}} dictionary. Note that a {{CaptureHandle}} object MUST NOT be given to a capturing application that is not permited to [=observable|observe=] it.
dictionary CaptureHandle { DOMString origin; DOMString handle; };
If the captured application opted-in to exposing its origin (by setting {{CaptureHandleConfig/exposeOrigin}} to true), then the user agent MUST set {{CaptureHandle/origin}} to the origin of the captured application. Otherwise, {{CaptureHandle/origin}} is not set.
The user agent MUST set this field to the value which the captured application set in {{CaptureHandleConfig/handle}}.
Extend {{MediaStreamTrack}} with a method called {{MediaStreamTrack/getCaptureHandle}}.
When the {{MediaStreamTrack}} is a video track derived of screen-capture,
{{MediaStreamTrack/getCaptureHandle}} returns the latest [=observable=] {{CaptureHandle}}.
Otherwise it returns null
.
partial interface MediaStreamTrack { CaptureHandle? getCaptureHandle(); };
If the track in question is not a video track, or is not the result of a capture of a
display surface
, then the user agent MUST return null
.
If the captured application did not set a {{CaptureHandleConfig}}, or if the last time
it set it to the empty {{CaptureHandleConfig}}, then the user agent MUST return
null
.
The user agent MUST compare the origin of the capturing document to those which the
captured application listed in {{CaptureHandleConfig/permittedOrigins}}. If the
capturing origin is not permitted to [=observable|observe=] the {{CaptureHandle}},
then the user agent MUST return null
.
If all previous validations passed, then the user agent MUST return a {{CaptureHandle}} dictionary with the values derived of the last {{CaptureHandleConfig}} set by the captured application.
Whenever the [=observable=] {{CaptureHandle}} for a given capturing application changes, the user agent fires an event of type CaptureHandleChangeEvent. This can happen in the following cases:
[Exposed=Window] interface CaptureHandleChangeEvent : Event { constructor(CaptureHandleChangeEventInit init); [SameObject] CaptureHandle captureHandle(); };
The track's {{CaptureHandle}} at the time the event was fired, as [=observable=] by the capturing application. If not [=observable=] by the capturing application, all of {{CaptureHandle}}'s fields will be set to their default value - the empty {{DOMString}}.
dictionary CaptureHandleChangeEventInit : EventInit { CaptureHandle captureHandle; };
The track's {{CaptureHandle}} at the time the event was fired.
{{MediaStreamTrack}} is extended with an {{EventListener}} called {{oncapturehandlechange}}.
partial interface MediaStreamTrack { attribute EventHandler oncapturehandlechange; };
{{EventHandler}} for events of type {{CaptureHandleChangeEvent}}.

HRW: Attacks against Sudan protesters were planned
by Aaron BrooksHuman Rights Watch (HRW) says the deadly attacks against Sudanese protesters calling for democratic change in June were planned and could amount to crimes against humanity.
The rights group is calling upon Sudan’s transitional government to conduct independent investigations and “commit to genuine accountability for unlawful violence against protesters since December, in which hundreds were killed.”
“They were shouting ‘kill them'”
In a 59-page report, entitled “‘They Were Shouting ‘Kill Them’’’: Sudan’s Violent Crackdown on Protesters in Khartoum, Human Rights Watch accuses Sudanese security forces of carrying out a planned attack against protesters in the capital on 3 June, 2019, and the days that followed in other neighbourhoods of the capital and nearby Bahri and Omdurman.
“The violence by Sudanese forces in the lead up to, during and following, the June 3 attack has killed hundreds of people, and was part of a pattern of using excessive force to disperse protests,” the report says. “Authorities did not use proportionate force or take feasible measures to ensure that operations posed a minimal risk to life.”
“Shooting was clearly targeted and intentional…; they directed their guns at us… they were shouting ‘kill them, kill them’ all the time. I saw many bodies hit by bullets while I was running,” one witness is quoted as saying in the report.
In a separate statement regarding the report, HRW directly accuses security forces in Sudan of planning the attack against protesters.
“Fatal attacks on protesters in Sudan in June were planned and could amount to crimes against humanity, Human Rights Watch said in a report released today,” the rights group said on Monday.

Snapchat says unlike Facebook it fact-checks all political ads
The platform has a team that fact-checks all political advertisements
by Aisha MalikSnapchat’s CEO has said that unlike Facebook, his company actually fact-checks political ads on its platform.
This statement comes as tech and social media giants have been facing pressure to address the spread of misinformation on their platforms.
Facebook has recently come under fire for deciding not to fact-check political ads. Twitter has also been criticized for initially stating that it decided to ban all political ads but is now struggling to determine what is considered political.
In comparison, Snapchat’s CEO, Evan Spiegel has now said that the platform has a team that fact-checks all political advertisements.
“We subject all advertising to review, including political advertising,” Spiegel told CNBC. “I think what we try to do is create a place for political ads on our platform, especially because we reach so many young people and first-time voters we want them to be able to engage with the political conversation, but we don’t allow things like misinformation to appear in that advertising.”
It should be noted that Snapchat’s advertising business is significantly smaller than that of Facebook and Twitter and that there aren’t many ads for the company to review.

I'm new to C++ and am having trouble with programming the output of the change after finding the differences between the price of the item and how much the user is going to pay. Here is the code I have so far. It works when the change is in 100's and 50's but after that it doesn't seem to work and I'm not sure where to go from here. I know there is a lot of extra calculating on here but I'd also like to keep it as simple as possible. Thank you!

Stop.
Just look it up, this is like one of the most highest homework question asked here, just look it up.


library(torch)
So far, all we’ve been using from torch is tensors, but we’ve been performing all calculations ourselves – the computing the predictions, the loss, the gradients (and thus, the necessary updates to the weights), and the new weight values. In this chapter, we’ll make a significant change: Namely, we spare ourselves the cumbersome calculation of gradients, and have torch do it for us.
Before we see that in action, let’s get some more background.
Torch uses a module called autograd to record operations performed on tensors, and store what has to be done to obtain the respective gradients. These actions are stored as functions, and those functions are applied in order when the gradient of the output (normally, the loss) with respect to those tensors is calculated: starting from the output node and propagating gradients back through the network. This is a form of reverse mode automatic differentiation.
As users, we can see a bit of this implementation. As a prerequisite for this “recording” to happen, tensors have to be created with requires_grad = TRUE
. E.g.
x <- torch_ones(2,2, requires_grad = TRUE)
To be clear, this is a tensor with respect to which gradients have to be calculated – normally, a tensor representing a weight or a bias, not the input data 1. If we now perform some operation on that tensor, assigning the result to y
y <- x$mean()
we find that y
now has a non-empty grad_fn
that tells torch how to compute the gradient of y
with respect to x
:
y$grad_fn
Actual computation of gradients is triggered by calling backward()
on the output tensor.
y$backward()
That executed, x
now has a non-empty field grad
that stores the gradient of y
with respect to x
:
x$grad
With a longer chain of computations, we can peek at how torch builds up a graph of backward operations.
Here is a slightly more complex example. We call retain_grad()
on y
and z
just for demonstration purposes; by default, intermediate gradients – while of course they have to be computed – aren’t stored, in order to save memory.
x1 <- torch_ones(2,2, requires_grad = TRUE) x2 <- torch_tensor(1.1, requires_grad = TRUE) y <- x1 * (x2 + 2) y$retain_grad() z <- y$pow(2) * 3 z$retain_grad() out <- z$mean()
Starting from out$grad_fn
, we can follow the graph all back to the leaf nodes:
# how to compute the gradient for mean, the last operation executed out$grad_fn # how to compute the gradient for the multiplication by 3 in z = y$pow(2) * 3 out$grad_fn$next_functions # how to compute the gradient for pow in z = y.pow(2) * 3 out$grad_fn$next_functions[[1]]$next_functions # how to compute the gradient for the multiplication in y = x * (x + 2) out$grad_fn$next_functions[[1]]$next_functions[[1]]$next_functions # how to compute the gradient for the two branches of y = x * (x + 2), # where the left branch is a leaf node (AccumulateGrad for x1) out$grad_fn$next_functions[[1]]$next_functions[[1]]$next_functions[[1]]$next_functions # here we arrive at the other leaf node (AccumulateGrad for x2) out$grad_fn$next_functions[[1]]$next_functions[[1]]$next_functions[[1]]$next_functions[[2]]$next_functions
After calling out$backward()
, all tensors in the graph will have their respective gradients created. Without our calls to retain_grad
above, z$grad
and y$grad
would be empty:
out$backward() z$grad y$grad x2$grad x1$grad
Thus acquainted with autograd, we’re ready to modify our example.
For a single new line calling loss$backward()
, now a number of lines (that did manual backprop) are gone:
### generate training data ----------------------------------------------------- # input dimensionality (number of input features) d_in <- 3 # output dimensionality (number of predicted features) d_out <- 1 # number of observations in training set n <- 100 # create random data x <- torch_randn(n, d_in) y <- x[,1]*0.2 - x[..,2]*1.3 - x[..,3]*0.5 + torch_randn(n) y <- y$unsqueeze(dim = 1) ### initialize weights --------------------------------------------------------- # dimensionality of hidden layer d_hidden <- 32 # weights connecting input to hidden layer w1 <- torch_randn(d_in, d_hidden, requires_grad = TRUE) # weights connecting hidden to output layer w2 <- torch_randn(d_hidden, d_out, requires_grad = TRUE) # hidden layer bias b1 <- torch_zeros(1, d_hidden, requires_grad = TRUE) # output layer bias b2 <- torch_zeros(1, d_out,requires_grad = TRUE) ### network parameters --------------------------------------------------------- learning_rate <- 1e-4 ### training loop -------------------------------------------------------------- for (t in 1:200) { ### -------- Forward pass -------- y_pred <- x$mm(w1)$add(b1)$clamp(min = 0)$mm(w2)$add(b2) ### -------- compute loss -------- loss <- (y_pred - y)$pow(2)$mean() if (t %% 10 == 0) cat(t, as_array(loss), "\n") ### -------- Backpropagation -------- # compute the gradient of loss with respect to all tensors with requires_grad = True. loss$backward() ### -------- Update weights -------- # Wrap in torch.no_grad() because this is a part we DON'T want to record for automatic gradient computation with_no_grad({ w1$sub_(learning_rate * w1$grad) w2$sub_(learning_rate * w2$grad) b1$sub_(learning_rate * b1$grad) b2$sub_(learning_rate * b2$grad) # Zero the gradients after every pass, because they'd accumulate otherwise w1$grad$zero_() w2$grad$zero_() b1$grad$zero_() b2$grad$zero_() }) }
We still manually compute the forward pass, and we still manually update the weights. In the last two chapters of this section, we’ll see how these parts of the logic can be made more modular and reusable, as well.
Unless we want to change the data, as in adversarial example generation↩

Numeric inputs will only allow you to type numbers. They will completely ignore all other characters. Full keyboard support is implemented. Try using up/down arrow keys, ctr + up/down (command + up/down on mac) to increase numbers. When the number is changed it will be validated and formatted (if needed).
