Subject [jira] [Updated] (MATH-917) More distance measurements are needed in o.a.c.m.stat.clustering.
Date Tue, 26 Mar 2013 21:47:15 GMT


Thomas Neidhart updated MATH-917:


The attached file updates the patch with all the suggestions:

 * change Clusterable method names
 * make DistanceMeasure interface more flexible
 * make algorithm classes immutable
 * make CentroidCluster a stand-alone class
 * remove generic types from Clusterable interface (not needed anymore)

Additionally, I have made the following changes:

 * modify packaging to base package ml
 * add MultiKMeansPlusPlusClusterer for multiple trials
 * use RandomGenerator instead of Random

> Currently only Euclidean distance is used for distance measurement, it would be easy
to quickly add Manhattan and Chebyshev distance among others.
