Definition Clustering can be considered the most important unsupervised learning technique; so, as every other problem of this kind, it deals with finding a structure in a collection of unlabeled data. Clustering is “the process of organizing objects into groups whose members are similar in some ...
Introduction : Clustering in data mining is a discovery process that groups a set of data The applications of clustering include : categorization of documents on the World Wide Web grouping of genes and proteins that have similar functionality characterization of different customer groups Clustering algo...

这个算法已经被提出了,并被大量应用在各个领域,这就是Clique Percolation Method。Clique的含义为“小党派”,在图论中,如果一个图中的几个点,两两之间都有边,则这几个点就构成了一个Clique。实现Clique Percolation Method,首先要找到所有的Clique。关于这个算法,我们这里不再展开,在这里推荐一个不错的PPT: ...
