ml.js - Machine learning tools in JavaScript
Introduction
This library is a compilation of the tools developed in the mljs organization.
It is mainly maintained for use in the browser. If you are working with Node.js, you might prefer to add
to your dependencies only the libraries that you need, as they are usually published to npm more often.
We prefix all our npm package names with ml- (eg. ml-matrix) so they are easy to find.
To include the ml.js library in a web page:
It will be available as the global ML variable. The package is in UMD format.

ML.ArrayXY
Functions dealing with an object containing 2 properties x and y, both arrays.
Example:
let result = ML.ArrayXY.sortX({ x: [2, 3, 1], y: [4, 6, 2] });
// result = {x: [1,2,3], y: [2,4,6]}

ML.ArrayXY.weightedMerge: Merge abscissa values on similar ordinates and weight the group of abscissa
-
ML.ArrayXY.maxMerge: Merge abscissa values on similar ordinates and keeps the abscissa with bigger ordinate value
-
ML.ArrayXY.closestX: Get the closest point for a specific abscissa value
-
ML.ArrayXY.centroidsMerge: Merge abscissa values if the ordinate value is in a list of centroids
-
ML.ArrayXY.sortX: Sort a set of point based on the abscissas values
-
ML.ArrayXY.maxY: Sort a set of point based on the abscissas values
-
ML.ArrayXY.uniqueX: Ensure that x values are unique
