Abstract: To achieve both efficiency and robustness in the support vector regression algorithm, multi-granularity granular ball computing is integrated into the support vector regression algorithm. A multi-granularity granular ball support vector regression algorithm is proposed based on granular ball computing. The radius information from granular balls is incorporated into the models constraint conditions, replacing the traditional sample point based support vector regression algorithm with a granular ball based support vector regression algorithm. Additionally, the dual model of the multi-granularity granular ball support vector regression is investigated, and a particle swarm optimization algorithm is utilized to solve it. Experimental results show that on both artificial datasets and University of California-Irvine(UCI)publicly available datasets, computational efficiency and robustness are improved by the multi-granularity granular ball support vector regression.
