The Research on Label Propagation Algorithm and Improvement Based on Local Information Mechanism

First, heuristic clustering method based on local information is introduced, second, the label propagation method based on local information is summarized, and then problem of the iterative process and a random strategy to select a node that belongs to the cluster structure are analyzed. Label propagation algorithm base on the similarity of node attributes is improved. At last, the experiments are used to help discover the efficient and availability of the algorithm, and put the algorithm into preliminary application.
