Matrix Representation

I removed "Matrix Representation" section because the following equation is wrong:

{\mathbf {S} }=C\cdot (\mathbf {W} ^{T}\cdot {\mathbf {S} }\cdot {\mathbf {W} })+(1-C)\cdot {\mathbf {I} }.

This does not guarantee S(i,i) = 1. Therefore this is different from SimRank; a star graph of order four (one vertex of degree three, and three vertices of degree one) is a concrete counterexample. (For more details, see our paper, to appear in KDD'14.) Tmaehara (talk) 04:26, 9 June 2014 (UTC)[reply]

CoSimRank

I moved the "CoSimRank" section to a new separate Wiki Page (which is under review now) because the model of CoSimRank is different from SimRank. — Preceding unsigned comment added by 80.43.142.207 (talk) 01:23, 7 August 2014 (UTC)[reply]

I would like to reinsert CoSimRank. Aparantly there is not enough information for a seperate Wiki Page. So I think displaying it here is better than nothing. Both concept are very similar and only differ in slightly in the matrix formulation (max or add). If no protest I will reinsert it in one week. Here is what it was looking like: http://speedydeletion.wikia.com/wiki/Draft:CoSimRank 2001:4CA0:4F01:1:219:99FF:FEF2:C501 (talk) 12:57, 12 May 2015 (UTC)[reply]
