BrainJS/brain.js
Brain.js
Brain.js is a JavaScript neural network library for building, training, and running machine learning models in the browser or Node.js. It provides implementations for several network types, including feedforward networks, recurrent neural networks for time series forecasting, and autoencoders for data compression and denoising.
The library features WebGL-based GPU acceleration to increase the speed of neural network computations on the graphics processor. It also includes a visualization tool that generates SVG images to represent the topology and layers of a feedforward network.
The framework covers the full machine learning workflow, from network construction and weight-based training to prediction execution and training set validation. Trained models can be persisted via JSON state serialization or converted into standalone JavaScript functions for use without the full library.
