Hello, I think that the problem is too complex and open to expect to find a tool that does the job. The question of what constitutes an interesting/relevant/useful feature for clustering is hard to answer. One approach is to go for feature extraction (dimensionality reduction) rather than feature selection.
If you have not already done so, you could look at the following references: R. A. Jarvis, E. A. Patrick. Clustering using a similarity measure based on shared nearest neighbours. IEEE Trans. Comput. C-22, 1025-1034 (1973). L. Ertoez, M. Steinbach, V.Kumar. Finding clusters of different sizes, shapes and densities in noisy, high dimensional data. Technical Report, 2002. T. Hofmann.

Looking for a feature selection tool, I've only faced packages for classification. As I do not have the class information (in my dataset) I am not able to use them. Do you know about any (free) feature selection software for clustering tasks? Thank you so much in advance.
