Kernel-based adaptation for affinity propagation clustering algorithm
|
Abstract:
AP algorithm has become increasingly popular in recent years as an efficient and fast clustering algorithm.AP has better performance on large and multi-class dataset than the existing clustering algorithms.But for the datasets with complex cluster structures,it cannot produce good clustering results.Through analyzing the property of data clusters,this paper proposed a kernel function,optimized that the parameters automatically according to the dataset structure,and the dataset in kernel space were linearly separable or almost linearly.Carried AP on the kernel space,it had a kernel-adaptive affinity propagation clustering algorithm(KA-APC).Compared with the original AP clustering,it had the advantages of effectively dealing with the large multi-scale dataset.The promising experimental results show that this algorithm outperforms the original AP algorithm.
