Javascript machine learning

Notes for browser-based machine-learning, for projects like synestizer or other javascript ai nerdery.


  • GANLab is a JS-backed generative adversarial network exploration tool, published as a paper
  • webcam transfer learning is an interesting essay in building a good UI for these things. It learns to use your webcam live.
  • diffcam is a webcam delta heatmap for motion detection.

Infrastructure, tooling

  • Teachable machine is a web-based tool that makes creating machine learning models fast, easy, and accessible to everyone.

    The models you make with Teachable Machine are real Tensorflow.js models that work anywhere javascript runs, so they play nice with tools like Glitch, P5.js, Node.js & more.

Plus, export to different formats to use your models elsewhere, like Coral, Arduino & more.

  • deeplearn.js, which can load tensorflow checkpoints Update: It’s now called tensorflow.js: “A WebGL accelerated, browser based JavaScript library for training and deploying ML models.” More precisely, “TensorFlow.js, an ecosystem of JavaScript tools for machine learning, is the successor to deeplearn.js which is now called TensorFlow.js Core.” Includes lots of sample code for integration with the browser etc.

    • subgraphs.js is a visual IDE for developing computational graphs, particularly designed for deep neural networks. Subgraphs is built with tensorflow.js, node, and react, and serves on Google Cloud.
  • keras-js runs pre-trained keras deep learning models in the browser

    Run Keras models (trained using Tensorflow backend) in your browser, with GPU support. Models are created directly from the Keras JSON-format configuration file, using weights serialized directly from the corresponding HDF5 file.

    Inspiration is drawn from a number of deep learning / neural network libraries for JavaScript and the browser, including Tensorflow Playground, ConvNetJS, synaptic, brain, CaffeJS, MXNetJS. However, the focus of this library is on inference only.

    Tensor operations are extended on top of the ndarray library. GPU support is powered by WebGL through weblas.

  • hardmaru presents an introduction to running sophisticated neural networks in the browser, targeted at artists

  • mlweb

    This looks genuinely amazing in terms of functionality and even includes native support for worker threads and concurrency. However… it is lacking modern web wrappings such as npm packaging etc, so is not convenient to use from e.g. webpack.

    Twin to lalolib, a linear algebra library.

  • Javascript inference and training: convnetjs

  • synapticjs is a full-featured javascript training, inference and visualisation system for neural network, with good documentation. Great learning resource, with plausible examples. Actively maintained.

    This library includes a few built-in architectures like multilayer perceptrons, multilayer long-short term memory networks (LSTM), liquid state machines or Hopfield networks, and a trainer capable of training any given network, which includes built-in training tasks/tests like solving an XOR, completing a Distracted Sequence Recall task or an Embedded Reber Grammar test, so you can easily test and compare the performance of different architectures.

  • javascript inference only, neocortex.js in the browser. Civilised, but untouched since February 2016.

  • brainjs is unmaintained now but looked like a simple javascript neural network library.

  • mindjs is a simple one where you can see the moving parts.

  • WebPPL is a successor to Church designed as a teaching language for probabilistic reasoning in the browser. Has hip features.

    • Runs on the command line with node.js or in the browser.
    • Supports modular and re-usable code using packages built on top of the npm package system, and interoperates with existing Javascript packages in the npm ecosystem.
    • Includes a large and expanding library of primitive distributions.
    • Implements a variety of inference algorithms, including exact inference via enumeration, rejection sampling, Sequential Monte Carlo, Markov Chain Monte Carlo, Hamiltonian Monte Carlo, and inference-as-optimization (e.g. variational inference).
    • Provides inference as a first-class operator in the language, allowing for nested inference (‘inference about inference’).
    • Supports optimizable models with neural network components using adnn.
