Abstract: Selecting highly predictive features from the high dimensional dataset is a formidable task. The existing feature selection algorithms available today are not dealing with multiple equally predictive subsets of features. We strongly believe that there is other subsets of features as well, which can give equivalent predictive accuracy as that of state-of-the-art algorithms. Statistically equivalent signature (SES) is one such feature selection algorithm, which is centred on constraint-based learning of Bayesian networks. The proposed model selects equivalent subsets of features from oral squamous cell carcinoma (OSCC) dataset with the help of SES. To inspect the validity of SES algorithms output, we are using K-nearest neighbour (KNN), support vector machine (SVM) and neural networks (NN) on each subset of predictive features. Finally, the results of proposed technique is compared with support vector machine - recursive feature elimination (SVM-RFE). SES produces more stable accuracy as compared to SVM-RFE.
