When processing some high-dimensional data, traditional machine learning algorithms may not be able to get satisfactory results, while feature selection can filter features of high-dimensional data before model training, reduce the number of features, and thus reduce the impact of problems caused by high-dimensional data. Feature selection can simultaneously eliminate features that are less correlated with categories or redundant with selected features, so as to improve classification accuracy and learning and training efficiency of high-dimensional data tasks. However, existing methods may remove redundancy inadequately or excessively in some cases. Therefore, this paper proposes a criterion for the feature redundancy, and based on this criterion, designs an effective feature selection algorithm to remove redundant features on the premise of ensuring maximum relevance to the target variable. The effectiveness and efficiency of the proposed algorithm are verified by experimental comparison with other algorithms that can remove redundant features.Read More
