基于非参数贝叶斯的聚类分析
Clustering Analysis Based on the Nonparametric Bayes
摘要
Abstract
Dirichlet process is supposed as the prior distribution of the weights parameters based on infinite Gaussian mixture model. Bayes theorem is used to deduce the estimators of parameters. The Gibbs sampling algorithm is applied to obtain the clustering number and the judge indicator factor of the observation data. Finally, we conduct simulation to show that our algorithm can effectively cluster data and our algorithm have lower error rate than the traditional clustering methods.关键词
