Clustering based on Similarity matrix
I have a similarity matrix between entities. Is there any clasutering
package in mahout which can cluster entities purely based on their
similarity matrix.
It will help if the clusters are hierarchical.
-Thanks,

It is quite possible to script a hierarchical clustering on top of any
clustering we have. Just cluster the biggest clusters as separate data
sets.

The spectral clustering uses similarity matrices. We have no hierarchical implementation.
