Abstract
The subject matter discloses systems and methods for selection of an optimum feature subset. According to the present subject matter, the system (102) implements the described method, where the method includes obtaining a plurality of features extracted from data sets associated with objects representing multiple classes, computing an intra-class variation factor and an inter-class variation factor for multiple feature subsets, from amongst the plurality of features, and identifying an optimum feature subset, from amongst the multiple feature subsets, based on minimization of the intra-class variation factor and maximization of the inter-class variation factor using differential evolution.
