Link Prediction Using Network Regression Model
This time on link prediction, rather than using a regular Random walk o predict links i will be using a new approach to predict links like regression . We know that the main approach of predicting links uses measures of network proximity adapted from graph ...

Link Prediction using Network based Inference - A quick matrix based implementation
I explored a paper proposed by Zhou etal used Network based Inference (NBI) method to predict missing links in bipartite network and was thinking a lot how to implement using some simple matrix ways. I have taken the pic below from Zhou paper above  to expl...

Lean Markov Chain Clustering in R
Markov Chain Clustering ( MCL) is fast scalable supervised clustering algorithm based on information flow in graphs. The algorithm finds cluster in graphs  by random walks. It used two important operators one is the inflation and other the expansion.  Expan...

You also mention "fast scalable."  (Macropol mentions this too.)  How?? Expansion is O(n^3).  Granted, it is parallelizable, but still...
Granularity also seems possibly problematic. Nevertheless, it is simple and an interesting way of thinking about graph clustering (fun!).   That it is not particularly amenable to overlapping clustering is curious.
