Reducing the LQG Cost with Minimal Communication
Oron Sabag, Peida Tian, Victoria Kostina +1
We study the linear quadratic Gaussian (LQG) control problem, in which the controller's observation of the system state is such that a desired cost is unattainable. To achieve the…
The Feedback Capacity of Noisy Output is the STate (NOST) Channels
Eli Shemuel, Oron Sabag, Haim Permuter
We consider finite-state channels (FSCs) where the channel state is stochastically dependent on the previous channel output. We refer to these as Noisy Output is the STate (NOST) c…
Feedback Capacity of MIMO Gaussian Channels
Oron Sabag, Victoria Kostina, Babak Hassibi
Finding a computable expression for the feedback capacity of channels with colored Gaussian, additive noise is a long standing open problem. In this paper, we solve this problem in…
Regret-Optimal LQR Control
Oron Sabag, Gautam Goel, Sahin Lale +1
We consider the infinite-horizon LQR control problem. Motivated by competitive analysis in online learning, as a criterion for controller design we introduce the dynamic regret, de…
Regret-Optimal Filtering for Prediction and Estimation
Oron Sabag, Babak Hassibi
The filtering problem of causally estimating a desired signal from a related observation signal is investigated through the lens of regret optimization. Classical filter designs, s…
