The classic algorithm of analysis clustering basing on uncertain data is discussed. The re-search actuality and new progress in uncertain data clustering algorithm in recent years are summa-rued in this paper. First the analysis and induction of some representative uncertain data clustering algorithms have been made from several aspects，such as the ideas of algorithm，key technology, ad-vantage and disadvantage. Second，several typical density-based algorithms and known data sets areselected; experiments are implemented and comparing with the same clustering of the data set under different algorithms. The clustor analysis was given by basing on compareding uncertain data in this paper. The above work can give a valuable reference for management of uncertain data.
