Abstract:

We propose to accelerate wrapper-based feature selection with a KNN classifier.We construct a classifier distance matrix to evaluate the quality of a feature.The proposed approach can apply to three types of wrapper-based feature selectors.Theoretical time complexity analysis proves the efficiency of the proposed approach.Experimental res...More
