Abstract: In this paper, we present a semi-supervised rough set-based random forest gene selection method for classification of data patterns. The proposed method tries to find the genes of interest known as significant genes and maximise the accuracy of the model with reduction percentage. The advantage of this approach is analysed by experimental results on three benchmark datasets such as leukaemia, colon cancer and SRBCT and results showed an improved accuracy over existing methods such as support vector machine, k-nearest neighbour and random forest. Finally, the performance of those selected significant genes has been measured using classifier validity and statistical measures. The experimental results and performance measures proves the efficiency of the proposed hybridised technique over traditional random forest method.
