A dynamic mean-field statistical model of academic collaboration
Soumendu Sundar Mukherjee, Tamojit Sadhukhan, Shirshendu Chatterjee
There is empirical evidence that collaboration in academia has increased significantly during the past few decades, perhaps due to the breathtaking advancements in communication an…
Learning with latent group sparsity via heat flow dynamics on networks
Subhroshekhar Ghosh, Soumendu Sundar Mukherjee
Group or cluster structure on explanatory variables in machine learning problems is a very general phenomenon, which has attracted broad interest from practitioners and theoreticia…
Consistent detection and optimal localization of all detectable change points in piecewise stationary arbitrarily sparse network-sequences
Sharmodeep Bhattacharyya, Shirshendu Chatterjee, Soumendu Sundar Mukherjee
We consider the offline change point detection and localization problem in the context of piecewise stationary networks, where the observable is a finite sequence of networks. We d…
Exact Tests for Offline Changepoint Detection in Multichannel Binary and Count Data with Application to Networks
Shyamal K. De, Soumendu Sundar Mukherjee
We consider offline detection of a single changepoint in binary and count time-series. We compare exact tests based on the cumulative sum (CUSUM) and the likelihood ratio (LR) stat…
