In current research, most researchers choose to reduce redundant attributes as many as possible through some attribution reduction algorithms. However, the misclassification cost induced by attribute reduction is ignored. Thus, it is worth studying that how to reduce redundant attributes based on preserving the misclassification cost. Firstly, in this paper, the degree of minimum misclassification is defined. Then, by introducing decision process into variable precision rough set, a new model which is based on minimum misclassification cost with variable precision rough set (VPRS) is proposed. Moreover, based on the minimum misclassification cost, a heuristic attribute reduction algorithm is proposed. Finally, the simulation result shows that a feasible and reliable set of attributes can be obtained with our algorithm. These results further enrich attribute reduction to effectively deal with the uncertain classification problems.<\/jats:p>","DOI":"10.3233\/jifs-18354","type":"journal-article","created":{"date-parts":[[2018,8,5]],"date-time":"2018-08-05T06:40:40Z","timestamp":1533451240000},"page":"5129-5142","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Attribute reduction based on misclassification cost in variable precision rough set model"],"prefix":"10.1177","volume":"37","author":[{"given":"Jingjing","family":"Yang","sequence":"first","affiliation":[{"name":"Chongqing Key Laboratory of Computational Intelligence, Chongqing University of Posts and Telecommunications, Chongqing, China"}]},{"given":"Qinghua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Chongqing Key Laboratory of Computational Intelligence, Chongqing University of Posts and Telecommunications, Chongqing, China"}]},{"given":"Qin","family":"Xie","sequence":"additional","affiliation":[{"name":"Chongqing Key Laboratory of Computational Intelligence, Chongqing University of Posts and Telecommunications, Chongqing, China"}]}],"member":"179","published-online":{"date-parts":[[2018,8,4]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/8986917"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/cpe.3830"},{"key":"e_1_3_2_4_2","unstructured":"BlakeC.L. and Merz.C.J.
