Unlabeled Sensing with Random Linear Measurements
Jayakrishnan Unnikrishnan, Saeid Haghighatshoar, Martin Vetterli
We study the problem of solving a linear sensing system when the observations are unlabeled. Specifically we seek a solution to a linear system of equations y = Ax when the order o…
Asymptotically Optimal Matching of Multiple Sequences to Source Distributions and Training Sequences
Jayakrishnan Unnikrishnan
Consider a finite set of sources, each producing i.i.d. observations that follow a unique probability distribution on a finite alphabet. We study the problem of matching a finite s…
On Minimal Trajectories for Mobile Sampling of Bandlimited Fields
Karlheinz Gröchenig, José Luis Romero, Jayakrishnan Unnikrishnan +1
We study the design of sampling trajectories for stable sampling and the reconstruction of bandlimited spatial fields using mobile sensors. The spectrum is assumed to be a symmetri…
Sampling High-Dimensional Bandlimited Fields on Low-Dimensional Manifolds
Jayakrishnan Unnikrishnan, Martin Vetterli
Consider the task of sampling and reconstructing a bandlimited spatial field in using moving sensors that take measurements along their path. It is inexpensive to increase…
Minimax Robust Quickest Change Detection
Jayakrishnan Unnikrishnan, Venugopal V. Veeravalli, Sean Meyn
The popular criteria of optimality for quickest change detection procedures are the Lorden criterion, the Shiryaev-Roberts-Pollak criterion, and the Bayesian criterion. In this pap…
Universal and Composite Hypothesis Testing via Mismatched Divergence
Jayakrishnan Unnikrishnan, Dayu Huang, Sean Meyn +2
For the universal hypothesis testing problem, where the goal is to decide between the known null hypothesis distribution and some other unknown distribution, Hoeffding proposed a u…
