A new scaling analysis to the Vlasov equation which describes gravitationalclustering is performed, and then it is argued with universe accelerative expanse modal.
A clustering result evaluating algorithm is presented in a gravitational way, where all the data points in the data space are regarded as the particles assigned with unit mass.
为了定量分析聚类算法的聚类结果,提出了基于引力概念的聚类质量评估算法。

Associated with the formation of galaxies in the universe is essentially a clustering process by gravitational attraction between galaxies role.
