Package Exports

dbvis-hc

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dbvis-hc) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

dbvis-hc

A TypeScript implementation a hierarchical clustering algorithm.

Install

Install with npm:

npm install --save dbvis-hc

This package requires module resoultion by Node in tsconfig.json:

"compilerOptions": {
    "moduleResolution": "node"
}

Usage

Example:

    const data = [ 10, 0.9, 1.0, 11, 1.1 ];
    // Distance function required by all linkage strategies 
    const distFunc = (a: number, b: number) => Math.abs(a - b);
    // Aggregation function only need by the controid linkage strategy
    const aggrFunc = (v: number[]) => v.reduce((acc, curr) => acc + curr, 0) / v.length;
    const hc = new HierarchicalClustering(data, new CentroidLinkage(distFunc, aggrFunc));
    const dendrogram = new Dendrogram<number>(hc.cluster(), 9.3);
    const clusters = dendrogram.extractClusters();
    // Output: [ [ 4, 1, 2 ], [ 0, 3 ] ]
