Minimal attribute reduction is the main research content in rough set theory. We find that in the traditional rough set attribute reduction algorithm, the rough set attribute reduction based on discrete particle swarm optimization (DPSO) performs well. However, the fitness function of this method has some limitations. When the minimum attribute reduction result is the conditional attribute set itself, the correct result cannot be obtained. For enhancing the accuracy and efficiency of attribute reduction, we propose an attribute reduction algorithm based on DPSO and variable precision rough set (VPRS). The proposed algorithm uses VPRS to process data more accurately. The new fitness function is constructed, and the attribute dependence is used as the function judgment basis. It can be adjusted automatically as the discrete binary particle swarm evolves, ensuring the convergence speed and evolution direction. Experimental results show that compared with traditional method, the proposed algorithm has stronger effectiveness and higher application value. <\/jats:p>","DOI":"10.1142\/s0219265921430301","type":"journal-article","created":{"date-parts":[[2022,2,10]],"date-time":"2022-02-10T09:05:53Z","timestamp":1644483953000},"source":"Crossref","is-referenced-by-count":0,"title":["Attribute Reduction Algorithm Based on Discrete Particle Swarm Optimization and Variable Precision Rough Set"],"prefix":"10.1142","volume":"22","author":[{"given":"Zhiyong","family":"She","sequence":"first","affiliation":[{"name":"College of Information Engineering, Xinjiang Institute of Technology, Akesu 843000, P.
