In this study, we applied a novel method by using correlation coefficient filter for dimensionality reduction followed by fuzzy rough quick reduct algorithm for feature selection. The classification performance was evaluated using the gene subsets obtained from correlation based filter and our proposed method. Later we compared the results with other traditional classifier techniques. After suitable experimental analysis, it has been found that our proposed method has a two-fold advantage namely selection of much lesser number of genes compared to correlation coefficient and improved classifier accuracy in majority of the cases. This approach also reduces the number of misclassifications that might occur in other approaches.
