Decision-Dependent Risk Minimization in Geometrically Decaying Dynamic Environments

AAAI 2022technical

This paper studies the problem of expected loss minimization given a data distribution that is dependent on the decision-maker's action and evolves dynamically in time according to a geometric decay process. Novel algorithms for both the information setting in which the decision-maker has a first o…

Best of many worlds: Robust model selection for online supervised learning

AISTATS 2019poster

We introduce algorithms for online, full-information prediction that are computationally efficient and competitive with contextual tree experts of unknown complexity, in both probabilistic and adversarial settings. We incorporate a novel probabilistic framework of structural risk minimization in…
