Neural networks in JavaScript

This is the source code for Robert Plummer's: 'Neural networks in JavaScript' course on Scrimba for Brain.js. Some files include bonus question answers and others don't.

'index.html' and 'counter.html' are the same, they just use different versions of Brain.js:

• 'index.html': Version 1.2.6.
• 'counter.html': Version 1.6.0.

'normalization.html' is used for the 'stockPredictor.js' file.

Source:

• Online Course: Neural networks in JavaScript

Setup

The code is meant to be run in a browser, so you just need an online HTML, JavaScript, CSS compiler such as:

• Scrimba's built in.
• JSFiddle.
• CodePen.
• jDoodle.
• Or your preferred one.

The output will be in the console, not in the HTML page itself.

If you do want to install it locally, then:

Clone this repository:

$ git clone https://github.com/xXH4CKST3RXx/JS-Neural-Networks-Course.git

Setup the project as a Web App

• How to build local Web App with Node.js

Install Brain.js locally:

NPM

If you can, install brain.js with npm:

npm install brain.js

CDN

<script src="//unpkg.com/brain.js"></script>

Download

Download the latest brain.js for browser

Installation note

Brain.js depends on a native module headless-gl for gpu support. In most cases installing brain.js from npm should just work. However, if you run into problems, this means that prebuilt binaries are not able to download from github reporsitories and you might need to build it yourself. If you would like, you can also install an earlier version of Brain.js if the installation fails.

npm rebuild
