Black-Box Generalization: Stability of Zeroth-Order Learning
Konstantinos E. Nikolakakis, Farzin Haddadpour, Dionysios S. Kalogerias +1
We provide the first generalization error analysis for black-box learning through derivative-free optimization. Under the assumption of a Lipschitz and smooth unknown loss, we cons…
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…
