A Domain Adaptive Density Clustering Algorithm for Data with Varying Density Distribution

1 code implementation23 Nov 2019 Jianguo Chen, Philip S. Yu

However, clustering algorithms based on density peak have limited clustering effect on data with varying density distribution (VDD), equilibrium distribution (ED), and multiple domain-density maximums (MDDM), leading to the problems of sparse cluster loss and cluster fragmentation.
