ABSTRACT

Cluster refers to the classic unsupervised learning method, whose mission is to group the samples as similar as possible within the cluster and between-cluster dierences as large as possible. The cluster is mainly divided hierarchical clustering, model-based clustering based clustering and density grid-based clustering and other types [2]. Due to the lack of sample class labels these teachers supervise signal, the parameters such as the number of clusters should be pre-specified in the cluster when the sample density was not significantly dierent, with low eciency and unknown actual classes of clusters.
