Example

const ExpectationMaximization = require('ml-expectation-maximization').ExpectationMaximization;
const em = new ExpectationMaximization();
em.train(data); // data is a training matrix
em.predict(toPredict); // data matrix to predict
 
/*
Get information about clusters obtained on the training step.
Each element of the array is a cluster with the following information
 
* weight: Weight of the current cluster.
* mean: Current mean of the cluster.
* covariance: Covariance matrix of the cluster.
* prediction: prediction label associated with the cluster.
*/
var data = em.getClusterData();
 
// save your model
