    MARC

    A tiny Markov chain generator in JavaScript

    Easily create Markov models from a given set of observations to generate random sequences of other potential observations. Larger data sets can be pre-computed using the new transition generator.

    Marc supports both time-homogeneous and higher-order Markov chains.

    Usage

    import Marc from 'marc';
    // Our observations consist of four sentences from a rando's Twitter account
    const observations = ['a sentence', 'another sentence', 'one more', 'and the last'];
    // Give Marc the observations and tell it our token delimiter (' ')
    const m = new Marc(observations, { delimiter: ' ', order: 1 });
    // Generate a probable observation
    const random = m.random();

    Run the example

    $> npm run example

    Pre Compute transitions (recommended for large data sets)

    With global install
    $> npm install -g @tmanderson/marc
    $> marc observations.json transitions.json
    From repo
    $> ./bin/index.js observations.json transitions.json

    The output transitions.json file can be used with Marc via setTransitions or when creating an instance.

    fetch('transitions.json')
      .then(res => res.json())
      .then(observations => {
        let marc = new Marc(observations, { delimiter: ' ', order: 0 }) // via constructor
        marc.setTransitions(observations); // or via transitions
      });
