Abstract: High-throughput technologies such as microarrays and mass spectrometry produced high dimensional biological datasets both in abundance and with increasing complexity. Prediction Analysis for Microarrays (PAM) is a well-known implementation of the Nearest Shrunken Centroid (NSC) method which has been widely used for classification of biological data. In this paper, a hybrid approach incorporating the Nearest Shrunken Centroid (NSC) and Memetic Algorithm (MA) is proposed to automatically search for an optimal range of shrinkage threshold values for the NSC to improve feature selection and classification accuracy. Evaluation of the approach involved nine biological datasets and results showed improved feature selection stability over existing evolutionary approaches as well as improved classification accuracy.
