Dynamic time warping for TypeScript.

Package Exports

  • dynamic-time-warping-ts

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 (dynamic-time-warping-ts) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

dynamic-time-warping-2

This is a typed version of the github.com/GordonLesti/dynamic-time-warping package, initially forked by fheyen.

Install

npm install dynamic-time-warping-ts

Usage

Importing the package

import DynamicTimeWarping from "dynamic-time-warping-ts";

Initialization

DynamicTimeWarping needs two arrays containing objects of the the same type and function that calculates the distance between two objects and returns a float.

const ser1 = [ 9, 93, 15, 19, 24 ];
const ser2 = [ 31, 97, 81, 82, 39 ];
const distFunc = ( a, b )=>  Math.abs( a - b );

const dtw = new DynamicTimeWarping(ser1, ser2, distFunc);

getDistance

Will return the distance of the dynamic time warping as float.

// 108
const dist = dtw.getDistance();

getPath

Will return the path of the dynamic time warping as array of arrays with two integers.

// [ [ 0, 0 ], [ 1, 1 ], [ 1, 2 ], [ 1, 3 ], [ 2, 4 ], [ 3, 4 ], [ 4, 4 ] ]
const dist = dtw.getPath();
