In real-life applications, information systems in RST often vary with time. Approximations of a concept in RST have been used to induce rules and need to update for dynamic data mining and related tasks. In addition, the values of the decision attributes in information systems may be fuzzy. An extension of classical rough set model, rough fuzzy set, is then presented to deal with such values. This paper focuses on approaches for dynamically updating approximations in rough fuzzy set when attribute values are coarsened or refined. The principles for dynamic maintenance of upper and lower approximations are firstly presented. Then, the algorithms are developed for updating approximations incrementally under the variation of attributes' values. Some examples are employed to illustrate the proposed methods. A comparison of the proposed incremental method with a non-incremental method for dynamic maintenance of approximations is conducted by an extensive experimental evaluation on the data set from UCI. The experimental results show that the incremental method effectively reduce the computing time in comparison with the non-incremental method.","PeriodicalId":133590,"journal":{"name":"2013 IEEE Symposium on Computational Intelligence in Dynamic and Uncertain Environments (CIDUE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133028603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to further reduce the number of fitness evaluations, a similarity-based evolution control method is introduced into the fitness estimation strategy for particle swarm optimization (FESPSO) [1]. In the proposed method, the fitness of a particle is either estimated or evaluated, depending on its similarity to the particle whose fitness is known. The performance of the proposed algorithm is examined on eight benchmark problems, and the simulation results show that the proposed algorithm is highly competitive on reducing the number of required fitness evaluations using the computationally expensive fitness function.","PeriodicalId":133590,"journal":{"name":"2013 IEEE Symposium on Computational Intelligence in Dynamic and Uncertain Environments (CIDUE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129287972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
