no code implementations16 Nov 2016 David Choi

Here, we develop a semidefinite program that can be tailored to other instances of the blockmodel, such as non-assortative networks and overlapping communities.

Co-clustering separately exchangeable network data

no code implementations17 Dec 2012 David Choi, Patrick J. Wolfe

This article establishes the performance of stochastic blockmodels in addressing the co-clustering problem of partitioning a binary array into subsets, assuming only that the data are generated by a nonparametric process satisfying the condition of separate exchangeability.
