Classification Imbalance as Transfer Learning
Eric Xia, Jason M. Klusowski
Classification imbalance arises when one class is much rarer than the other. We frame this setting as transfer learning under label (prior) shift between an imbalanced source distr…
Krylov-Bellman boosting: Super-linear policy evaluation in general state spaces
Eric Xia, Martin J. Wainwright
We present and analyze the Krylov-Bellman Boosting (KBB) algorithm for policy evaluation in general state spaces. It alternates between fitting the Bellman residual using non-param…
Instance-Dependent Confidence and Early Stopping for Reinforcement Learning
Koulik Khamaru, Eric Xia, Martin J. Wainwright +1
Various algorithms for reinforcement learning (RL) exhibit dramatic variation in their convergence rates as a function of problem structure. Such problem-dependent behavior is not…
Instance-optimality in optimal value estimation: Adaptivity via variance-reduced Q-learning
Koulik Khamaru, Eric Xia, Martin J. Wainwright +1
Various algorithms in reinforcement learning exhibit dramatic variability in their convergence rates and ultimate accuracy as a function of the problem structure. Such instance-spe…
