Codes for paper "A novel community detection method based on density clustering algorithm" by Tao You and Zhong-Yuan Zhang. To run the tests, just load the files and run demo.m in Matlab. All codes are tested under Matlab Version 2015b 64bit and Matlab Version 2010a 32bit This document contains following files: 1.IsoFdp.m %the main Codes of the proposed algorithm 2.IsomapII.m %faster version of isomap 3.dijkstra.mexw64 %64bit compiled version of dijkstra algorithm which is much faster than the Floyd's algorithm 4.dijkstra.mexw32 %32bit compiled version of dijkstra algorithm 5.demo.m %% show how to use the algorithm 6.LFR_data %% the synthetic dataset to test the algorithm 7.readme Note: The codes from line 31 to line 72 in IsoFdp.m is changed. By utilizing sparse matrix and custom function in pdist, this version of 'structure similarity' is about 100x faster than the original one which is coded by double for-loop. Feedback is very welcome.
