is the process of selecting an optimal subset of features from a given set of features; an optimal feature subset is the one which maximizes the performance of the model on the given task. Feature selection can be a manual or rather explicit process when performed with filter or wrapper methods. In these methods, features are added or removed iteratively based on the value of a fixed measure, which quantifies the relevance of the feature in the making the prediction. The measures could be information gain, variance or the chi-squared statistic, and the algorithm would make a decision to accept/reject…
