摘要:
摘要： Many real-world and man-made objects are symmetry, therefore, it is reasonable to assume that some kind of symmetry may exist in data clusters. In this paper a new cluster validity measure which adopts a non-metric distance measure based on the idea of "line symmetry" is presented. The proposed validity measure can be applied in finding the number of clusters of different geometrical structures. Several data sets are used to illustrate the performance of the proposed measure. 出版者： Taipei: 社團法人中華民國計算語言學學會 出版日期： 2014-03-01 出處： Journal of Information Science and Engineering, 2014-03, Vol.30 (2), p.443-461 資源來源： Chinese Electronic Periodical Services (CEPS) 版權： 2015 INIST-CNRS 識別號： ISSN: 1016-2364 識別號： DOI: 10.6688/JISE.2014.30.2.10
