LOSP

These codes are for our paper "Detecting Overlapping Communities from Local Spectral Subspaces"

Requirements

Before compiling codes, the following software should be installed in your system.

• Matlab
• gcc (for Linux and Mac) or Microsoft Visual Studio (for Windows)

Datasets Information

• SNAP datasets (available at http://snap.stanford.edu/data/)

Example dataset

• Amazon dataset (available at http://snap.stanford.edu/data/com-Amazon.html)
• nodes: 334863, edges: 925872
• nodes are products, edges are co-purchase relationships
• top 5000 communities with ground truth size >= 3

How to run LOSP algorithm

$ cd LOSP_codes 
$ matlab 
$ LOSP

How to run baseline algorithms

run LEMON algorithm

$ cd baseline_codes/LEMON
$ matlab 
$ LEMON

run HK algorithm

$ cd baseline_codes/HK
$ matlab 
$ mex -largeArrayDims hkgrow_mex.cpp   % compile the mex file 
$ HK
