Amir Mahdi Abdolhosseini-Qomi, Naser Yazdani, Masoud Asadpour

Modularity functions maximization with nonnegative relaxation facilitates community detection in networks

Jonathan Q. Jiang, Lisa J. McQuay
2012 Physica A: Statistical Mechanics and its Applications  
With the explicit nonnegative constraint, our solutions are very close to the ideal community indicator matrix and can directly assign nodes into communities.  ...  Therefore, the proposed method can be exploited to identify the fuzzy or overlapping communities and thus facilitates the understanding of the intrinsic structure of networks.  ...  This description is just an intuitive concept rather than a rigorous definition, and thus is far way from meeting the requirement for detecting communities in graphs via computational algorithms.  ...
