Using Brain.js is a fantastic way to create a neural network. Learn patterns and relationships between inputs and outputs so you can make reasonably informed hypotheses about related questions. An example of a neural network is the image recognition system associated with Cloudinary.
JavaScript for neural networks? What does it mean? I was also surprised when I first read the Brain.js documentation, but I really liked it.
TL;DR
In this article we will discuss some aspects to understand how neural networks work. We'll learn terms like forward and backward propagation, as well as other terms used in the machine learning community. Next, we'll leverage the power of Brain.js to build a daily meeting scheduling app using a constitutional neural network.
Prerequisites
Before continuing, this article assumes that:
Node.js ≥ v6 is installed on your computer
npm is installed on your computer
Do you know JavaScript
What is a neural network?
Artificial neural networks are ultimately analytics, a replication of the mechanism through which neural networks operate, which represents the ability to learn. These systems “learn” to perform tasks based on examples, often without being programmed with specific task rules.
What does this mean?
Humans learn primarily by comparing patterns and pixels to infer what pixels visually represent when they are all together. It uses a method called multilayer perceptron, which produces decent gradients. It works by combining patterns at different points in the neural chain until you get a result where pixels match edges, then edges match patterns, and finally patterns match shapes. For a more complete understanding of this concept, check out this tutorial.
If you are working with a Node.js application, you can install Brain.js into your project using the following methods that we cover in this section.
Installation with NPM
If you can install Brain.js with npm:
npm install Brain.js
Ensure the following dependencies are installed and updated and run:
npm build
We are currently using Brain.js with CDN implementation.
Deploy via CDN
Create a simple XOR gate
This is not exactly the purpose of sending. I would like to use this example to explain forward and backward propagation and at the same time explain some of the components that make up Brain.js. We can configure our project like a normal application.
An XOR gate is a logical gate that generates a 0 when the two input values are equal. and returns 1 if the inputs have different values. We will implement it in the following steps.
In index.html, we import the Brain.js library via a CDN as follows:
