Abstract

In this paper, we elaborate on how feature selection methods traditionally employed in classification problems can be adapted for clustering problems, assuming that the number of clusters is not known a priori. Computational complexity of each described algorithm is provided. Empirical results in six bioinformatics datasets illustrate that the adaptation of four well-known supervised methods for feature selection (correlation-based, consistency-based, wrapper of k-NN classifier, and C4.5) can be useful for clustering tasks.
