Decision rules for efficient classification of biological data

Cancer classification using genomic data is one of the major research areas in the medical field. Therefore, a number of binary classification methods have been proposed in recent years. Top Scoring Pair (TSP) method is one of the most promising techniques that classify genomic data in a lower dimensional subspace using a simple decision rule. In the present paper, we propose a supervised classification technique that utilizes incremental generalized eigenvalue and top scoring pair classifiers to obtain higher classification accuracy with a small training set. We validate our method by applying it to well known microarray data sets.
