Markov Cluster AlgorithmMartin L. Jäger
Markov CLustering or the Markov CLuster algorithm, MCL is a method for clustering weighted or simple networks, a.k.a. graphs. It is accompanied in this source code by other network-related programs, one of which is RCL (restricted contingency linkage) for fast multi-resolution consensus clusteri...
But, he adds, the computational biology community is encountering a computing bottleneck because the tool mostly runs on a single computer node, is computationally expensive to execute and has a big memory footprint—all of which limit the amount of data this algorithm can cluster. One of the ...

Briefly, the modularity (Q) can be considered to be the fraction of graph edges which belong to a cluster minus the fraction expected due to random chance, where the value of Q lies in the range [-1, 1]. High, positive Q values suggest higher clustering quality. ...
When MCL converges, each column ofMhas at least one nonzero element. All nodes whose corresponding columns have a nonzero element in the same row are assigned to the same cluster. If a node has multiple nonzero elements in its column, a row is arbitrarily chosen. Although MCL is simple ...

Section 2.2 introduces a new spectral method to cluster graph nodes with the objective of maximum association, the dual problem of minimum cut. Section 2.3 shows how to con- struct the stochastic matrix of a random walk from a graph so as to perform spectral clustering. In Section 2.4, we ...
