Implementation of the scalable graph embedding method suggested in [1]

NOTE THAT THIS IS NOT THE IMPLEMENTATION OF THE AUTHORS OF [1] AND IT IS NOT GUARANTEED TO WORK. The implementation of the authors of [1] is/will be here: https://github.com/ZW-ZHANG/RandNE.

gcc RandNE.c -o RandNE -O9 -lm

./RandNE net.txt emb.txt d q a0 a1 ... aq

• net.txt should contain on each line: "u v\n" that is the input undirected graph.
• emb.txt contains the resulting embedding (d floats on each line)
• d is the dimension of the embedding
• q is the order of the embedding
• ak's are the coefficient of A^k matrix such as defined in [1]

On http://snap.stanford.edu/data/com-Orkut.html

• d=32 and q=3: 5 minutes
• d=32 and q=5: 10 minutes
• d=128 and q=3: 20 minutes
