| Abstract: | This paper introduces three approaches of cluster evaluation including external, internal, and relative which are based on the definition of clustering optimization problem. And several representative quality measures are introduced. Moreover, the characters of various measures and optimal effects of partitioning are discussed in detail. Finally, the application problem of clustering assessment is summarized. |
