TensorFlow.js for training and deploying ML models in the browser and on Node.js (was called Deeplearnjs)
- Keras.js No longer active - capability now is in TensorFlow.js
- Deeplearnjs rebranded to TensorFlow.js
TensorFlow Playground written in Javascript (TypeScript) using D3.js
Brain.js
ML5.js
Natural provides tokenizing, stemming (reducing a word to a not-necessarily morphological root), classification, phonetics, Term Frequency–Inverse Document Frequency (TF-IDF), WordNet, string similarity, some inflections, and more. (nodejs)
Neuro.js Learning to Drive project a deep learning and reinforcement learning Javascript library framework for the browser. Implementing a full stack neural-network based machine learning framework with extended reinforcement-learning support
TensorFire is a framework for running neural networks in the browser, accelerated by WebGL
ConvNetJS an NPM version is also available for those using Node.js, and the library is designed to make proper use of Javascript’s asynchronicity with neural networks supporting common modules, classification, Regression, an experimental Reinforcement Learning module, able to train (Deep) Convolutional Neural Network (DCNN/CNN) that process images
mljs includes supervised and unsupervised learning, artificial neural networks, Regression algorithms and supporting libraries for statistics, math etc.
Synaptic multilayer perceptrons, multilayer long-short term memory networks, liquid state machines and a trainer capable of training a verity of networks
Webdnn this framework optimizes the Deep Neural Network (DNN) model to compress the model data and accelerate execution through Javascript APIs such as WebAssembly and WebGPU
Neataptic neuro-evolution & backpropagation for the browser
Mind make predictions, using a matrix implementation to process training data and enabling configurable network topology.
DeeForge a development environment for deep learning
MXnet.js deep learning in browser (without server); allows you to mix symbolic and imperative programming on the fly with a graph optimization layer for performance
Handtrack.js: Hand Tracking Interactions in the Browser using Tensorflow.js and 3 lines of code | Victor Dibia - Towards Data Science - allows you track a user’s hand (bounding box) from an image in any orientation
