Risk-Aware Stability of Discrete-Time Systems
Margaret P. Chapman, Dionysios S. Kalogerias
We develop a generalized stability framework for stochastic discrete-time systems, where the generality pertains to the ways in which the distribution of the state energy can be ch…
State-Output Risk-Constrained Quadratic Control of Partially Observed Linear Systems
Nikolas Koumpis, Anastasios Tsiamis, Dionysios Kalogerias
We propose a methodology for performing risk-averse quadratic regulation of partially observed Linear Time-Invariant (LTI) systems disturbed by process and output noise. To compens…
Model-Free Learning of Optimal Deterministic Resource Allocations in Wireless Systems via Action-Space Exploration
Hassaan Hashmi, Dionysios S. Kalogerias
Wireless systems resource allocation refers to perpetual and challenging nonconvex constrained optimization tasks, which are especially timely in modern communications and networki…
Noisy Linear Convergence of Stochastic Gradient Descent for CV@R Statistical Learning under Polyak-Łojasiewicz Conditions
Dionysios S. Kalogerias
Conditional Value-at-Risk () is one of the most popular measures of risk, which has been recently considered as a performance criterion in supervised statistical lea…
Zeroth-order Deterministic Policy Gradient
Harshat Kumar, Dionysios S. Kalogerias, George J. Pappas +1
Deterministic Policy Gradient (DPG) removes a level of randomness from standard randomized-action Policy Gradient (PG), and demonstrates substantial empirical success for tackling…
Risk-Constrained Linear-Quadratic Regulators
Anastasios Tsiamis, Dionysios S. Kalogerias, Luiz F. O. Chamon +2
We propose a new risk-constrained reformulation of the standard Linear Quadratic Regulator (LQR) problem. Our framework is motivated by the fact that the classical (risk-neutral) L…
