How do purely functional languages handle index-based algorithms?

Asked 2022-Apr-05 at 12:51

I have been trying to learn about functional programming, but I still struggle with thinking like a functional programmer. One such hangup is how one would implement index-heavy operations which rely strongly on loops/order-of-execution.

For example, consider the following Java code:

This is not an index-heavy operation, in fact you can do this with a one-liner with scanl1 :: (a -> a -> a) -> [a] -> [a]:

Keras AttributeError: 'Sequential' object has no attribute 'predict_classes'

Im attempting to find model performance metrics (F1 score, accuracy, recall) following this guide https://machinelearningmastery.com/how-to-calculate-precision-recall-f1-and-more-for-deep-learning-models/

This exact code was working a few months ago but now returning all sorts of errors, very confusing since i havent changed one character of this code. Maybe a package update has changed things?

I fit the sequential model with model.fit, then used model.evaluate to find test accuracy. Now i am attempting to use model.predict_classes to make class predictions (model is a multi-class classifier). Code shown below:

ANSWER

Answered 2021-Aug-07 at 16:34

You need to specify the events which you want your bot to receive using gateway intents.

Instead of

const client = new Discord.Client();

Use

const client = new Discord.Client({ intents: [Enter intents here] })

For example

const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] })

The ItemProperties component has multiple root nodes because it renders a list in the root with v-for.

Based on the class name (infobox-item-properties), I think you want the class to be applied to a container element, so a simple solution is to just add that element (e.g., a div) in your component at the root:

Group and create three new columns by condition [Low, Hit, High]

Asked 2022-Feb-10 at 16:22

I have a large dataset (~5 Mio rows) with results from a Machine Learning training. Now I want to check to see if the results hit the "target range" or not. Lets say this range contains all values between -0.25 and +0.25. If it's inside this range, it's a Hit, if it's below Low and on the other side High.

I now would create this three columns Hit, Low, High and calculate for each row which condition applies and put a 1 into this col, the other two would become 0. After that I would group the values and sum them up. But I suspect there must be a better and faster way, such as calculate it directly while grouping. I'm happy for any idea.

Since C++17 the order of evaluation is specified such that the operands of = are evaluated right-to-left and those of << are evaluated left-to-right, matching the associativity of these operators. (But this doesn't apply to all operators, e.g. + and other arithmetic operators.)

Flutter (2.5) - A splash screen was provided to Flutter, but this is deprecated

Asked 2022-Jan-19 at 05:24

I am new to flutter and recently tried to develop a test app for learning sake with latest version Flutter 2.5. By looking at some tutorial online, I have added flutter_native_splash: ^1.2.3 package for splash screen. And works fine.

However, when I launch app for the first time, it shows following debug message

W/FlutterActivityAndFragmentDelegate(18569): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.

After visiting the above link, I am not able to understand much what is supposed to be done.

ANSWER

Answered 2022-Jan-19 at 05:24

To avoid that warning you just need to remove that API usage from your project. Remove these lines of code from the AndroidManifest.xml file.

Previously, Android Flutter apps would either set io.flutter.embedding.android.SplashScreenDrawable in their application manifest, or implement provideSplashScreen within their Flutter Activity. This would be shown momentarily in between the time after the Android launch screen is shown and when Flutter has drawn the first frame. This is no longer needed and is deprecated – Flutter now automatically keeps the Android launch screen displayed until Flutter has drawn the first frame. Developers should instead remove the usage of these APIs. - source

UPDATE (FLUTTER 2.8.0)

As per the flutter 2.8.0 update, The newly created project doesn't have this warning.

They removed unused API from Androidmanifest.yml but still have belove mentioned code.

Install merb-book

You can download it from GitHub.
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.

Support

Install the github gem from http://github.com/defunkt/github-gem/tree/master. Fork the mattetti/merb-book project by clicking the fork button at http://github.com/mattetti/merb-book/tree/master. Clone a copy of the repository to the local machine. Choosing from the branches in Mattetti’s repo (i.e., ‘english’), select the LANGUAGE you're going to contribute to. Enter the merb-book directory. Checkout the remote branch for the LANGUAGE that you're working on. Checkout a local copy of your language branch. Do a sanity check. Set up a remote branch on github for your language. Modify, fix, and add content in your local LANGUAGE branch. Commit your changes into your local Git repository. Merge in the upstream changes. Push your changes back to github. Send Mattetti a pull request. For the moment, the content of the book is located inside ./book-content/ and is organized by languages, chapters, and pages. Chapters and pages must be lowercase and start by a digit followed by a dash and the chapter/page title without spaces or any non ascii characters. All content files are Markdown files; the merb app uses maruku to render these files. Check the supported syntax or check ./book-content/en/1-introduction/1-ruby.markdown for a good example of how to use images, quotes, and CSS selectors. The book supports multiple languages. Each language needs to replicate the English folder structure, using the same file names.
