Economy Statistical Recurrent Units For Inferring Nonlinear Granger Causality
Saurabh Khanna, Vincent Y. F. Tan
Granger causality is a widely-used criterion for analyzing interactions in large-scale networks. As most physical interactions are inherently nonlinear, we consider the problem of…
On the Restricted Isometry of the Columnwise Khatri-Rao Product
Saurabh Khanna, Chandra R Murthy
The columnwise Khatri-Rao product of two matrices is an important matrix type, reprising its role as a structured sensing matrix in many fundamental linear inverse problems. Robust…
On the Support Recovery of Jointly Sparse Gaussian Sources using Sparse Bayesian Learning
Saurabh Khanna, Chandra R. Murthy
In this work, we provide non-asymptotic, probabilistic guarantees for successful recovery of the common nonzero support of jointly sparse Gaussian sources in the multiple measureme…
Decentralized Joint-Sparse Signal Recovery: A Sparse Bayesian Learning Approach
Saurabh Khanna, Chandra R. Murthy
This work proposes a decentralized, iterative, Bayesian algorithm called CB-DSBL for in-network estimation of multiple jointly sparse vectors by a network of nodes, using noisy and…
