In the current era of information overload, most of the datasets are high dimensional and often consist of many irrelevant and redundant features, thus making it complex and less efficient to model and analyze the data. It is, therefore, necessary to reduce the number of features required to achieve high classification performance. The feature selection algorithm looks for the optimal or most informative features by putting aside the redundant and irrelevant features, retaining accurate information and data structures where possible, resulting in efficient and more accurate predictive models. Various feature selection techniques have been developed and are continually nurtured to meet the evolving needs. This talk is intended to explore and analyze the effectiveness of Monte Carlo Tree Search (MCTS) in feature selection. MCTS is a dynamic search strategy and have proven its effectiveness in gaming domains with huge search spaces. MCTS finds the optimal solutions probabilistically by using lightweight random simulations. The feature selection task is modeled with a binary tree and modified MCTS is applied to the tree to select effective feature subsets. The proposed algorithms efficiently search the feature space and find the best feature subset within a few iterations to achieve high classification accuracy and reduced dimensions.
