Minor Description
Under "Power Iteration Clustering", the reference to the paper describing the method redirects to the web site for the conference at which it was originally published.
The correct reference, as taken from Lin's web page at CMU, should be:
Ihttp://www.cs.cmu.edu/~frank/papers/icml2010-pic-final.pdf
(at least, I think that's the one - someone who knows the algorithm should probably check it's the right one - I'm trying to follow it because I don't know it, of course
