报告摘要:Community detection refers to the problem of clustering the nodes of a network into groups. Testing the existence of community structure in a network is a fundamental problem. Existing methods are developed for unweighted networks. However, many practical networks are weighted. In this talk, I will introduce an information theoretical limit for testing existence of community structure in weighted networks, and present two practical tests.
