artificial intelligence neural network in javascript

To create an artificial neural network in JavaScript, you can use the library called brain.js. This library is designed to simplify the process of creating neural networks by providing a simple and flexible API.

To get started, you need to install the brain.js library using npm by running the following command:

index.tsx
npm install brain.js

2 lines

Once the library is installed, you can use it to create a neural network by defining its architecture and parameters, training it on a dataset, and then using it to make predictions.

Here's an example of creating a simple neural network using brain.js that learns to recognize handwritten digits from the MNIST dataset:

index.tsx
const brain = require('brain.js');

// Define the network architecture
const net = new brain.NeuralNetwork({
  hiddenLayers: [16, 16], // two hidden layers with 16 neurons each
  activation: 'sigmoid', // activation function for the neuron
});

// Train the network on the MNIST dataset
net.train([
  { input: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], output: [0, 0, 0, 0, 0, 0, 0, 0, 0, 1] }, // represents the digit 9
  // ... more training data ...
]);

// Make a prediction using the trained network
const result = net.run([0, 1, 0, 0, 1, 0, 0, 0, 0, 0]); // predicts the digit 4

console.log(result); // prints [0, 0, 0, 0, 1, 0, 0, 0, 0, 0]

This is just a basic example to get you started. You can customize the network architecture, activation function, and training algorithm to suit your specific needs.
