Abstract: Feature subset selection is the process of identifying and removing many irrelevant and redundant features. Initially, the input micro array dataset is selected from the medical database. Then, preprocessing step is done in the input dataset. The resultant output is fed to the second step; here, the features are optimally selected using clustering and tree generation process. In our proposed technique, the modified kernel-based fuzzy c-means clustering algorithm with optimal minimum spanning tree algorithm is applied on the high dimensional dataset to select the important features, in which the optimal features are selected by means of binary cuckoo search. Next, the classification is done through neuro fuzzy classifier. At last, the experimentation is performed by means of different micro array dataset. The result proves that neuro fuzzy classifier outperformed the existing approach by attaining maximum accuracy of 89% for GLA-BRA-180 dataset when compared existing NN only achieved 68.2%, fuzzy classifier attains 63.1% and KNN classifier attains 67.3%.
