Accelerating wrapper-based feature selection with K-nearest-neighbor
作者:
Highlights:
• 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 results demonstrate its effectiveness and efficiency.
