K-Means Clustering

K-Means Clustering algorithm with integrated upper limit for iteration count

Install

Installing with npm npm install --save @enigmaoffline/kmeans-clustering

Usage

const Cluster = require("@enigmaoffline/kmeans-clustering");

const dataPoints = [
  [2, 10],
  [2, 5],
  [8, 4],
  [5, 8],
  [7, 5],
  [6, 4],
  [1, 2],
  [4, 9],
];

const cluster = new Cluster(3, dataPoints);
cluster.setDistanceMethod(Cluster.DIST.MANHATTAN);
cluster.setDecimalPoints(2);
cluster.setLimit(300);

cluster.getClusters().then((res) => console.log(JSON.stringify(res)));

/*
    res = {
        "centroids": [[3.67, 9], [1.5, 3.5], [7, 4.33]],
        "clusters": [[[2, 10], [5, 8], [4, 9]], [[2, 5], [1, 2]], [[8, 4], [7, 5], [6, 4]]]
    }
*/
FunctionFunctionality
constructor()takes two parameters1) number of clusters (k)2) datapoints
setDistanceMethod()sets the distance calculation method, either euclideandistance, or manhattan distance.
setDecimalPoints()sets the number of decimal points centroids are roundedto on return.
setLimit()sets the upper limit of iterations the algorithm will runbefore it quits even though thevalues have yet to converge.
getClusters()async function that groups datapoints into k clustersterminates on either1) all values converge and no changes happen2) iteration count exceeds upper limit
