Distribution-based clustering -- Gaussian mixture models 基于分布的聚类 --例如:高斯混合模型 Density-based clustering -- kernel density estimation 基于密度的聚类 -- 例如:核密度估计 Grid-based clustering 基于网格的集群 再初步了解一下connectively-based clustering 基于连接的聚类 基于连接的聚类(也称为分层...
Traditional density-based clustering methods that focus on full-dimensional dense clusters are not well suited to such situations. CLIQUE searches for subspace clusters with a bottom-up approach that exploits a monotonicity property with respect to dimensionality to prune search space. The monotonicity ...
We review grid-based clustering, focusing on hierarchical density-based approaches. Finally, we describe a recently developed very efficient (linear time) hierarchical clustering algorithm, which can also be viewed as a hierarchical grid-based algorithm. This review adds to the earlier version, ...

Under the Hard or Crisp, six major categories are identified: the Search-based method, the Graph-theoretic method, Density-based, Model-based, Sub-space, and Miscellaneous. The complete taxonomy for these clustering methods is shown in Fig. 1. Sign in to download hi-res image Fig. 1. ...
DP (Density Peak) is a novel density-based clustering method [7]. It is based on two assumptions: that the cluster centers have a higher density than those of their neighbors, and that they are also relatively far away from other high-density points. DP is simple and easy to implement,...
