Mutual information feature selection algorithm based on electronic nose sensor performance

Abstract： In order to improve the generalization performance, most of the current mutual information feature selection algorithms have not optimized the specific application field, and electronic nose sensor array optimization is a special feature selection problem. It is difficult to search for the optimal feature subset using traditional algorithms. Combining the special redundancy and unique sensitivity of the gas sensor array, this paper proposes a mutual information feature selection optimization algorithm based on the performance of the electronic nose sensor. The influence of the sensor characteristics on the recognition accuracy is verified through two different electronic nose public data sets，which proved the effectiveness of the proposed algorithm.
