Feature selection is an important task during classification of any pattern. In this paper, we compute and compare the strengths of five most widely used feature ranking techniques in identifying the optimal subset of features for best classification results. The feature ranking measurements that are used here are information gain (IG), gain ratio (GR), correlation, symmetrical uncertainty (SU), and chi-square (CS). For evaluation purpose, recognition of handwritten numeral samples from five popular Indic scripts—Bangla, Hindi, English, Telugu, and Arabic—are used. These ranking methods are applied over quadtree-based longest run feature set. Experimental results are drawn and compared using support vector machine (SVM)-based classifier.
