- Abstract:
-
The application scopes of traditional classification algorithms based on feature selection are limited due to the single evaluation criteria of redundancy and relevance adopted. To solve this problem, this paper proposes a new maximum relevance, minimum redundancy (MRMR) feature selection algorithm, which enlarges its application scope by introducing two different evaluation criteria to measure the redundancy between features of measurement, measuring the correlation between features and categories, and deriving eight different feature selection algorithms. In addition, because the traditional MRMR feature selection algorithms cannot realize feature selection according to the data dimension of users’ actual demand, the study also applies an indicator vector $\lambda$ to achieve that, proposes a new objective function to obtain the optimal feature subset, and conducts experiments on four feature subsets of UCI using a support vector machine. Finally, the study verifies the effectiveness of the algorithm using classification accuracy and pairs of unilateral T-tests.
