Examples

Multi-Dimensional Scaling (PivotMDS)

import * as hdsp from "hdsp";
hdsp.PivotMDS.project(
    [
        [1,0,0,1,0,0,0,1],  // feature vector 1
        [0,1,1,0,1,1,1,1],  // feature vector 2
                            // ...
        [0,0,0,1,0,1,0,1]   // feature vector n
    ],
    4, // number of pivots
    2  // output dimensionality
);

Procrustes Analysis (2D)

import * as hdsp from "hdsp";
hdsp.Procrustes.transform(
    [[0,0],[0,-2],[-1,-1]],  // input
    [[0,0],[0,2],[1,1]]      // reference
);
