Feature selection is an important preprocessing step for any pattern classification or data mining problem. The main objective of feature selection is to retain the most discriminatory information for classification or the most characteristic information for knowledge extraction. Basically it comprises of two steps. The first one deals with the evaluation measure for evaluating a feature or a feature set and the second one deals with the search algorithm for finding out the best feature subset from all possible subsets of features according to the selected evaluation measure.

In this talk, I would like to present some of our proposed evaluation measures and their merits and demerits. I would also like to show the effectiveness of their use with proposed search algorithms using soft computing techniques for feature subset selection by simulation results with bench mark data sets.
