Gilles Sadowski 7741ddb814 Track changes. 2020-03-22 16:08:31 +01:00
Gilles Sadowski 4128dbb206 Merge branch 'MATH-1509__ChenTao' 
Closes #128.
 2020-03-22 15:10:26 +01:00
Gilles Sadowski ab33121f7b Use "sample" functionality from "ListSampler". 
Change should improve performance by
 * extracting the number of required items (instead of shuffling the whole list),
 * converting the "Collection" to a "List" once.

Gilles c13179ef73 Javadoc. 2020-03-15 01:38:10 +01:00
Gilles aef8f5272d Reduce visibility of method that is meant to be used internally only. 
Note: Since "Cluster" is mutable, the "center" stored in "CentroidCluster"
may become inconsistent with the actual contents of the cluster.
See MATH-1524.
 2020-03-13 04:07:48 +01:00
Gilles cd0988f9bf Method "centroid()" is available for any "Cluster" instance (userguide). 
See MATH-1524.
