public class RAkEL
extends RAkELd

RAkEL.java - Draws M subsets of size k from the set of labels, and trains PS upon each one, then combines label votes from these PS classifiers to get a label-vector prediction. The original RAkEL by Tsoumakas et al. was a meta method, typically taking LC (aka LP) as a classifier; this implementation is more like a combination between RAkEL and PS, making it potentially very fast (recall that PS defaults to LC with 0 pruning). See also RAkEL from the MULAN framework.
