Machine learning tools in JavaScript

Overview

ml.js - Machine learning tools in JavaScript

Introduction

This library is a compilation of the tools developed in the mljs organization.
It is mainly maintained for use in the browser. If you are working with Node.js, you might prefer to add to your dependencies only the libraries that you need, as they are usually published to npm more often.
We prefix all our npm package names with ml- (eg. ml-matrix) so they are easy to find.

To include the ml.js library in a web page:

<script src="https://www.lactame.com/lib/ml/4.0.0/ml.min.js"></script>

It will be available as the global ML variable. The package is in UMD format.

List of included libraries

Unsupervised learning

Supervised learning

Artificial neural networks (ANN)

  • Feedforward Neural Networks: ML.FNN
  • Self-organizing map / Kohonen networks: ML.SOM

Regression

Optimization

Math

ML.Array

ML.ArrayXY

Functions dealing with an object containing 2 properties x and y, both arrays.

Example:

let result = ML.ArrayXY.sortX({ x: [2, 3, 1], y: [4, 6, 2] });
// result = {x: [1,2,3], y: [2,4,6]}

  • Way to reuse model saved and retrieved from JSON?

    Way to reuse model saved and retrieved from JSON?

    Hello,

    I am wondering if there is a way/can be added to reuse a model that has been generated, stored, and retrieved. For instance, I have created a pls model object, stored it as JSON, and inserted it into a database. When I retrieve the model object it says that "predict" is not a function. I found a similar implementation at http://mlweb.loria.fr/demos/mljs-tutorial-storage.html for just SVM and kernel ridge regression. I adjusted it so that I can store and retrieve my pls model perfectly, but the predict functionality is gone.

  • Updated ml npm package

    Updated ml npm package

    Hi guys,

    First of, I love the work and the modular approach to constructing this library.

    When is the next planned semver release on NPM, a lot of the individual packages have been updated (likeml-naivebayes) and it would be great to have them rolled up into a package again.

    Thanks, Yaw

  • how to integrate in browser

    how to integrate in browser

    Hello,

    Can you please post an example how to integrate ml.js with requireJS for use in a browser?

    I'm trying to use ML.savitzkyGolay. I dont't get how to integrate the library.

    It will be available as the global ML variable. The package is in UMD format and can be "required" within webpack or requireJS.

    I don't get a variable ML if I use <script src="https://www.lactame.com/lib/ml/2.2.0/ml.min.js"></script>

    I can get functions like ML.AU.SNV and ML.propertyIsEnumerable with <script src="./src/ml.min.js" charset="utf-8"></script>

    or

    <script src="https://www.lactame.com/lib/ml/2.2.0/ml.min.js"></script>
    ...
    requirejs(["ML"])
    
    

    but none of the function mentioned on the GitHub site are available.

    I would be very thankful if you can point me in the right direction.

  • Update dependencies

    Update dependencies

    Hello @mljs/collaborators, in the CONTRIBUTING.md file I tried to merge all the guidelines, but those are open to discussion off course.

    For example will be interesting decide if we make our own commit guidelines, because it's not always clear which case to use, so won't be a bad idea to look other ones as guides, like the atom's one.

    I also think that we should have a v1.0.0 version, because we have a stable API and is used in production.

  • Cleanup and update repositories

    Cleanup and update repositories

    There have been a lot of changes in how we structure and test our projects since the creation of this org. Here are some things that need to be cleaned up or changed, and a list of repositories where to do it.

    To do

    1. Rename some config files

    If they exist:

    • .babelrc -> .babelrc.json
    • .prettierrc -> .prettierrc.json

    2. Move Prettier config from package.json to .prettierrc.json.

    There are some projects where the Prettier config is not in a separate file (example). Copy the config to a file named .prettierrc.json and remove the field from the package.json.

    3. Rename prepublishOnly script to prepack

    If it exists in package.json.

    4. Add prettier and prettier-write scripts

    In package.json:

    {
      "scripts": {
        "prettier": "prettier --check src",
        "prettier-write": "prettier --write src"
      }
    }
    

    The "test" script should be updated to call npm run prettier at the end.

    Example

    5. Update dependencies

    ncu -u
    

    Be careful if there are breaking changes in non-dev dependencies. Check the changelog of the dependency and adapt the project if necessary.

    6. Remove eslint-plugin-* from dependencies

    After updating dependencies, we can do this because the eslint-config-cheminfo packages have the plugins as peer dependencies. Make sure to use the latest version of Node.js 16 or 17, otherwise it won't work.

    7. Refactor how tests are run

    There are multiple things to do here. See floyd-warshall for an example of a correct setup.

    • If there is a test-coverage npm script, remove it.
    • If there is a testonly npm script, rename it to test-only.
    • Add --coverage to the test-only npm script. For example: "test-only": "jest --coverage"
    • If there is a "jest" field with only "testEnvironment": "node" in it, remove the field. The latest version of Jest defaults to this environment.
    • Otherwise, if there are more things in the Jest config. Move it to a jest.config.js file.

    8. Rename History.md to CHANGELOG.md

    • Rename the file
    • Add # Changelog + a new line at the beginning.

    Example

    9. Remove Travis config

    • Delete `.travis.yml
    • Delete Travis-related lines from README.md

    10. Remove david config

    Delete david-related lines from README.md

    Example

    11. Remove docs folder

    If it exists.

    12. Setup or update GitHub workflows

    • If the workflow doesn't exist, create it.
    • If the workflow already exists, replace it with the new template. node-version-matrix should contain 12 if Node.js 12 was tested in the old workflow.
