Brain.js is a JavaScript library used for neural networking, which is released as free and open-source software under the MIT License. It can be used in both the browser and Node.js backends.
Brain.js is most commonly used as a simple introduction to neural networking, as it hides complex mathematics and has a familiar modern JavaScript syntax. It is maintained by members of the Brain.js organization and open-source contributors.
Examples Creating a feedforward neural network with backpropagation: const net = new brain.NeuralNetwork();
net.train([ { input: [0, 0], output: }, { input: [0, 1], output: }, { input: [1, 0], output: }, { input: [1, 1], output: }, ]);
console.log(net.run([1, 0]));
Creating a recurrent neural network: const net = new brain.recurrent.RNN();
net.train([ { input: [0, 0], output: }, { input: [0, 1], output: }, { input: [1, 0], output: }, { input: [1, 1], output: }, ]);
let output = net.run([0, 0]); // output = net.run([0, 1]); // output = net.run([1, 0]); // output = net.run([1, 1]); //
Train the neural network on RGB color contrast: const net = new brain.NeuralNetwork();
net.train([{ input: { r: 0.03, g: 0.7, b: 0.5 }, output: { black: 1
},
input: { r: 0.16, g: 0.09, b: 0.2 }, output: { white: 1
},
input: { r: 0.5, g: 0.5, b: 1.0 }, output: { white: 1
]);
const output = net.run({ r: 1, g: 0.4, b: 0 }); // { white: 0.99, black: 0.002 }
console.log(output)
