Sparse and Low-bias Estimation of High Dimensional Vector Autoregressive Models

no code implementations L4DC 2020 Trevor Ruiz, Sharmodeep Bhattacharyya, Mahesh Balasubramanian, Kristofer Bouchard

A well-known feature of RML inference is that in general the technique produces a trade-off between sparsity and bias that depends on the choice of the regularization hyperparameter.

Hierarchical community detection by recursive partitioning

no code implementations2 Oct 2018 Tianxi Li, Lihua Lei, Sharmodeep Bhattacharyya, Koen Van den Berge, Purnamrita Sarkar, Peter J. Bickel, Elizaveta Levina

This can be done with a simple top-down recursive partitioning algorithm, starting with a single community and separating the nodes into two communities by spectral clustering repeatedly, until a stopping rule suggests there are no further communities.

Spectral Clustering and Block Models: A Review And A New Algorithm

no code implementations7 Aug 2015 Sharmodeep Bhattacharyya, Peter J. Bickel

We focus on spectral clustering of unlabeled graphs and review some results on clustering methods which achieve weak or strong consistent identification in data generated by such models.
