[Java-ML-support] KMedoids

[Hailpern, J. <jos...@hp...>]

Kmeans works fine. However, when I try to run Kmedoids (same input) I get a NoSuchElementException.


Exception in thread "main" java.util.NoSuchElementException

at java.util.HashMap$HashIterator.nextEntry(HashMap.java:796)

at java.util.HashMap$KeyIterator.next(HashMap.java:828)

at net.sf.javaml.clustering.KMedoids.recalculateMedoids(KMedoids.java:150)

at net.sf.javaml.clustering.KMedoids.cluster(KMedoids.java:86)

at _06.cluster.KmeansModeling.<init>(KmeansModeling.java:71)

at Debug.main(Debug.java:69)

Please advise if possible, considering it works correctly on kmeans.
