A simple feed-forward neural network library written in JavaScript, usable in Node.js and the browser. It supports training on input/output patterns and running predictions, and is officially end-of-life in favor of brain.js and convnetjs.

Use cases

• train a simple feedforward neural network in javascript
• approximate functions like xor with a neural net
• classify inputs like color contrast in the browser
• run a pretrained network with toJSON or toFunction
• learn how neural networks work in javascript

When to choose

• you need a tiny, dependency-free neural network for simple patterns
• you are maintaining legacy code that already uses brain
• you want a minimal educational example of neural network training

When to avoid

• you need an actively maintained library - use brain.js or convnetjs instead
• you need deep learning features like convolutions, recurrent networks, or GPU acceleration
• you need production-grade performance or modern tooling
