X-Means always same behavior
I'm trying to use X-means due to its advantages against K-means, but Im not getting the proper result.
I tried K-means to evaluate 6 files from 3 categories and with a k = 3 it worked perfectly.
than i try to apply the Xmeans from 2 to 60 and I get always 2 clusters.
I though it could be because of having few files so I tried again with 53 files from 3 categories,
and the result were the same. K-means(k=3) successful, X-means (k = 2 - 60) the same 2 clusters.
I've tried many configurations but the most use are
measure type: NumericalMeasures
numerical measure: CosineSimilarity
clustering algoritm: KMeans
the rest is default.
I'm Clueless about the reason any help is appreciate!
