- Abstract:
-
The K-harmonic means algorithm(KHM) has the disadvantage of easily falling into a local optimum. To solve this problem, we propose a hybrid KHM based on an improved firefly algorithm(FA). In this paper, we combined raw FA-based searching with parallel chaotic FA-based elaborate searching. In the elaborate searching, we found the current best and second-best solutions using the FA, then we used an improved logistic map model combined with parallel chaotic optimization to search this area in order to enhance the searching ability of the algorithm. Finally, we used the improved FA to optimize the cluster centers obtained by the KHM. Experimental results demonstrate that the proposed algorithm not only had higher search precision for several test functions, but also improved the clustering accuracy and stability of six datasets, effectively avoiding being trapped into a local optimum.
