GitHub Link:

Short for Standard Lib, stdlib is a standard library for JavaScript and Node.js that offers a range of numerical and scientific calculation capabilities for your Machine Learning applications. As one of the top frameworks on the list of the best Javascript Machine Learning Libraries the library comes with a wide array of mathematical functions to help you build statistical models, data visualization capabilities to transform your data into visuals and extract insights, while also including other helpful utilities that make application development and library development easier. Stdlib’s integrated read-eval-print-loop makes use of the numerous built-in functions and helps in manipulating data, enabling quick prototyping.

The stdlib library also serves as a great all-in-one general purpose package that comes packed with extensive documentation, including several high-quality examples, tests, and benchmarks to help you start developing for Machine Learning.

3. TensorFlow.js

GitHub Link:

Google’s Tensorflow.js is one of the most popular Machine Learning and Deep Learning libraries for JavaScript. With tensorflow.js, you can perform a range of tasks, such as building and training Machine Learning models, running JavaScript and non-JavaScript Machine Learning models on the browser or Node.js, and even retraining existing models. It can also process pre-trained models as long as they’re from Keras or a TensorFlow SavedModel format.

All that tensorflow.js has to offer is broken into simple and efficient APIs, such as the core API, layers API, converter API, and more. The library also comes with built-in support for different backgrounds or platforms, such as WebGL, WebGPU, CPU backend, Node, to name a few. To give you an idea of its popularity, tensorflow.js is already being used in diverse sectors like education and healthcare.

4. Deeplearnjs

GitHub Link:

Now turned into tensorflow.js core, Deeplearnjs is an intuitive open-source JavaScript Machine Learning library on the list of the best Javascript Machine Learning Libraries. The deeplearnjs library supports hardware-acceleration and comes equipped with all the building blocks required for training and running pre-trained Machine Learning models in your browser.

The library offers two APIs, one is an immediate execution model like NumPy, while the other is a deferred execution model resembling the TensorFlow API. The deeplearnjs library was originally developed by the Google Brain’s PAIR team for the development of deep learning models and has been used for a variety of projects such as education, art, understanding models.

5. Machinelearn.js

GitHub Link:

Written in TypeScript, Machinelearn.js is a ScikitLearn like JavaScript Machine Learning library for the web and Node.js. It shares similarity with brain.js as both of these libraries emphasize on making Machine Learning as simple and straightforward as possible. The library is perfect for solving Machine Learning problems and teaching the workings of the several Machine Learning algorithms available with its learning APIs.

At its core, machinelearn.js uses TensorFlow.js to provide an all-in-one library for ML developers with features, such as clustering, bagging, ensemble, linear models, feature extraction. Although the library is quite fast, you can enable acceleration using C++ binding or by using a GPU.

6. Mind


GitHub Link:

The Mind library for JavaScript lets you easily train Neural Networks in your browser or in Node.js to make better predictions. Mind as one of the best Javascript Machine Learning Libraries is pretty flexible to work with and offers features such as a matrix implementation for processing training data, network topology customizability, and the ability to download or upload minds that have completed learning.

Mind’s website is home to an interesting implementation of the library in the form of a movie recommendation system that provides a hands-on experience and showcases its capabilities.

7. ConvNetJS


GitHub Link:

The beauty of JavaScript libraries is that some of them come with zero software requirements, you just need to have a browser, and that’s it. The same can be said for ConvNetJS, which is a JavaScript Machine Learning library for training your Deep Learning models entirely from your browser. Apart from supporting browsers, the library also supports Node.js.

At the moment, ConvNetJS offers support for classification, regression (L2) cost functions, training Convolutional Networks for image processing, common Neural Network modules containing non-linearities and fully connected layers, and an experimental Reinforcement Learning module based-off Deep Q Learning. The library has some browser-based demos to give you an idea about it. But do keep in mind that the developer is not actively maintaining the library anymore.

8. Neuro.js

GitHub Link:

Neuro.js is a JavaScript Machine Learning library built with a primary reason for creating chatbots and smart Artificial Intelligence-powered assistants by the likes of Google Assistant, Siri, and so on. The library is also good for creating and training JavaScript Machine Learning models and deploying them in the browser or Node.js.

The simple and performance-driven Neuro.js library aims to make Machine Learning practical and accessible to everyone granting it its well-deserved spot on the list of the best javascript machine learning libraries. This open-source library comes with several features, such as online learning, real-time classification, supports binary as well as multi-label classification, and more.

9. WebDNN


GitHub Link:

WebDNN is a Deep Neural Network framework developed by the University of Tokyo’s Machine Intelligence Laboratory to solve the growing computational requirements and to increase the availability of a DNN for end-users. The WebDNN’s JavaScript API makes it easy to run DNNs on the browsers by optimizing the trained DNN models by compressing them, which greatly helps with the accelerated execution of the said models.

The user of these efficient JavaScript APIs, such as WebAssembly and WebGPU is the key to achieving practically zero execution overhead with WebDNN.

10. Keras.js


GitHub Link:

Keras.js is another fairly popular and open-source JavaScript library that lets you run Keras’ Machine Learning models in your browser. Keras, one of the best Javascript Machine Learning Libraries, also includes GPU support via WebGL. You can run the models in Node.js, but they’ll be restricted to CPU mode only, which means no GPU acceleration. As Keras abstracts several frameworks as backend, you can train your models on any backend of your choice, including CNTK and TensorFlow.

The demos folder in their GitHub repo contains over 8 interactive demos based on real-world problems that can give you a hands-on idea of the capabilities and working of keras-js.

11. Synaptic

GitHub Link:
Synaptic is a JavaScript library for Neural Networks, which you can use from browser and Node.js. Claimed to be an architecture-free library, synaptic lets you build and train any kind of first or second-order Neural Network architectures.
