Regret-Optimal Control for Finite-State Systems
Yishay Polatov, Oron Sabag
We study the control of finite-state systems driven by exogenous disturbances, and design causal policies that track the performance of a lookahead benchmark controller. This objec…
Optimal Competitive-Ratio Control
Oron Sabag, Sahin Lale, Babak Hassibi
Inspired by competitive policy designs approaches in online learning, new control paradigms such as competitive-ratio and regret-optimal control have been recently proposed as alte…
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…
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…
