Feature Selection for Clustering

some are important for clusters while others may hinder the clustering task. An efficient way of handling it is by selecting a subset of important features.

Unsupervised Feature Selection for the k-means Clustering Problem

It is worth not- ing that feature selection selects a small subset of actual features from the data and then runs the clustering algorithm only on the selected

Feature clustering and mutual information for the selection of

Spectral data often have a large number of highly-correlated features making feature selection both necessary and uneasy. A methodology combining hierarchical
