JellyBrain is a simple neural network written in Javascript. This was written as an exercise to learn how neural networks work.
const JellyBrain = require('./JellyBrain');
let brain = new JellyBrain(2, 2, 1); // 2 inputs, 2 hidden nodes, 1 output
brain.train([0.2, 0.5], 1);
brain.guess([0.1, 0.6]);
