An Auto-clustering Algorithm Based on Gene Expression Programming

CHEN Yu,TANG Chang-jie,YE Shang-yu,LI Chuan,JIANG Yue,LIU Qi-hong(School of Computer Sci.,Sichuan Univ.,Chengdu 610064,China)  
Many clustering algorithms have to need a number of clusters before clustering.In order to tackle this problem,a novel GEP-Cluster(Gene Expression Programming-clustering) algorithm was proposed.The main contributions include: 1) proposing the GEP-Cluster algorithm to find the best clustering via GEP evolution,2) proposing AMCA algorithm to auto merge cluster,3) finding the best clustering without any priori knowledge by the GEP-Cluster algorithm.Extensive experiments showed that GEP-Cluster algorithm is effective in clustering without any domain knowledge,and the average clustering accuracy is almost 96%.
