On Codes with Support-Constrained Parity Checks
Barron Han, Hikmet Yildiz, Babak Hassibi
We study linear codes that maximize minimum distance subject to arbitrary support constraints on the parity-check matrix. Such constraints arise naturally in the design of LDPC cod…
Quantized Online LQR
Barron Han, Victoria Kostina, Babak Hassibi
We study online linear-quadratic regulation (LQR) with unknown dynamics under communication rate constraints. Classical networked control quantizes the plant state at every time st…
Coded Kalman Filtering over MIMO Gaussian Channels with Feedback
Barron Han, Oron Sabag, Victoria Kostina +1
We consider the problem of remotely stabilizing a dynamical system. A sensor (encoder) co-located with the system communicates with a controller (decoder), whose goal is to stabili…
Robust Mean Estimation With Auxiliary Samples
Barron Han, Danil Akhtiamov, Reza Ghane +1
In data-driven learning and inference tasks, the high cost of acquiring samples from the target distribution often limits performance. A common strategy to mitigate this challenge…
