Long Short Term Memory networks – usually just called “LSTMs” – are a special kind of RNN, capable of learning long-term dependencies. They were introduced by Hochreiter & Schmidhuber (1997), and were refined and popularized by many people in following work. They work tremendously well on a large variety of problems, and are now widely used. LSTMs are explicitly designed to avoid the vanishing gradient problem. All recurrent neural networks have the form of a chain of repeating modules of neural network. In standard RNNs, this repeating module will have a very simple structure, such as a single tanh layer. LSTMs also have this chain like structure, but the repeating module has a different structure. Instead of having a single neural network layer, there are four, interacting in a very special way.

QUESTION
I'm currently using the ARIMA model to predict a stock price, SARIMAX(0,1,0). I wanted to forecast stock prices on the test dataset with 95% confidence interval. I'm following this tutorial posted July 2021, but some things have changed and I can't figure out what.
The original code are as follows:
...ANSWER
Answered 2022-Mar-28 at 11:23Note that to set the forecast indices and confidence intervals, we subtract 57 from the total number of elements. Data is also requested for the upper and lower confidence interval, for their subsequent drawing(conf_ins = fitted.get_forecast(57).summary_frame()).

I am trying to navigate btw screens using gesture detector but getting an error message how do i fix this?
Error
======== Exception caught by gesture =============================================================== The following assertion was thrown while handling a gesture: Navigator operation requested with a context that does not include a Navigator.
The context used to push or pop routes from the Navigator must be that of a widget that is a descendant of a Navigator widget. When the exception was thrown, this was the stack: C:/b/s/w/ir/cache/builder/src/out/host_debug/dart-sdk/lib/internal/js_dev_runtime/private/ddc_runtime/errors.dart 236:49 throw packages/flutter/src/widgets/navigator.dart 2732:9 packages/flutter/src/widgets/navigator.dart 2738:14 of packages/task1/main.dart 78:10 [_navigateToNextScreen] packages/task1/main.dart 60:21 ...

...ANSWER
Answered 2021-Oct-07 at 09:59What is Navigator.of(context)?
When you call Navigator.of(context) flutter tries to get the Navigator of the given context.
Why do you get the error?
Navigator is put in the widget tree be MaterialApp, therefore, any context bellow MaterialApp should be able to call Navigator.of(context).
You are using the context of MyApp which is above MaterialApp, hence the error.
Solution
You need to get a context which is bellow MaterialApp. An easy way to achieve this is to use the Builder widget.
Here is your code with the use of Builder to get the right context:
QUESTION
I'm learning node.js and working on a project for creating an web application to manage stock market portfolio for investors. I don't know how to send the captured data from an API to a table cell in html. Here is my node.js code
...ANSWER
Answered 2021-May-30 at 18:03There's quite a lot to unpack here as you say you're a beginner. It would be more like a lesson telling you how to make a major part of your application, rather than an answer fixing a bug. All I can do is point you to some resources that might help you.
EJS Documentation
This is for what's called server-side rendering. With this you'll be able to put the data into the file before serving it to the client.
Fetch Documentation
Use this if you would want the client to query data. (Meaning the data is loaded through a script file on the page itself)
About Async/Await
fetch has quite a lot of references to promises and async functions, so this will be of huge help to you. From looking at your code it also seems you'll be running into callback issues (you will probably try to access res in a callback at some point, which wouldn't be a good idea). Using async/await will help you to get around those issues.
PS: Sorry if this isn't what you expected as an answer, I'm just trying to help you out.
QUESTION
I Want To Scrape The Table Data From This Website.But if i go to the page source code it does not show me the the table part of the full pages source but shows the table tag in the inspect. Can anybody please help me to scrape the data form this website.
...ANSWER
Answered 2021-Apr-22 at 20:55The table does not show up in the source code because it is rendered by Angular. BeautifulSoup only sees the plain HTML source. You can
- take a look at this question, where selenium is recommended for such pages (because it executes the javascript, making the stuff you see in the devtools via inspect scrape-able) or
- inspect the requests made in Javascript with the "Network" tab in the devtools. There, you switch to "XHR", which shows requests by JS, reload the page and look through the results. As you can see in my screenshot the NSE request gets the data you're after. Copy the request URL and request it directly to get a json result with just your answer. This should work in this case but for some APIs you will have to have a closer look at the headers tab, since some cookies or security tokens might be required to get a valid answer.
QUESTION
I am trying to parse and save all the information between all the
tags in ('div', class_='WYSIWYG articlePage') into first column and all the information from the tag in ('div', class_='contentSectionDetails') into the second column in one .csv file (https://www.investing.com/news/stock-market-news/learjet-the-private-plane-synonymous-with-the-jetset-nears-end-of-runway-2419023). So the problem is that I have a thousands urls (URLs are generated based on numbers from the ALL_NUMBERS file) and I want to save this data in a single .csv file line by line from each url.
So I have the next code:

Answered 2021-Mar-25 at 09:35Pandas might be a bit overkill, you could just use the built in CSV library to write a row at a time:
QUESTION
Well, I am new to BS in Python. I have written a code that scrapes HTML and save all the data that I need in csv file. The values from the ALL_NUMBERS file are substituted into the URL and thus a large number of URLs are obtained.
The code is below:

QUESTION
Here is an example code for a WidgetExtension that should show the link preview image retrieved using the LinkPresentation. I am guessing the widgets dont load url data directly but need to be somehow fetched using the geTimeline and defined there somehow? How is it done?
Using the standard widget template in Xcode just adding the Metadata
...ANSWER
Answered 2021-Mar-03 at 16:39AFAIK WidgetKit does not observe Views, but only render them once and discard them afterwards. Thus your approach of having an @StateObject doesn't work as WidgetKit has already discarded the View when your request returns.
As you already guessed you have to do every asynchronous task inside of either getSnapshot or getTimeline.
Below is a minimal working example reusing some of your code. Of course you might want to adapt configuration of the url, error handling and timeline-strategy according to your needs.
Note that I don't know if any of this is considered best practice...I only know it works :)
QUESTION
I'm trying to collect news articles off yahoo finance using selenium. I got it to work with 1 article, but when I try looping over the different articles it doesn't make the click. The reason I have the second 'except' 'continue' is because there are ads in between the articles which I don't want to click. The structure of the XPath of the articles are either somthingdiv[1] or somethingdiv[2] and the 'li[]' part differs for every article (+1 for every article). Does someone have any idea what I'm doing wrong? Or does someone have a better way to do this?
Here is my current code:
...ANSWER
Answered 2021-Jan-26 at 23:03I suggest you to look do it using BeatuifulSoup.
You just need to scape the webpage. Selenium is useful when you need a real browser to click, input values, navigate to other pages ect...
With BeatifulSoup it will be easyer and faster.
You can do something like this:

Need help getting a full list of pictures that are uploaded with the codes below then save it to an array:
...ANSWER
Answered 2021-Jan-17 at 07:46Its happen because you setState inside of loop. Update your handleImageUpload like this, it works fine for me.
If you setState inside of loop, DOM will re-render in every setState. Thats why it shows the last image.
