The surprising efficiency of temporal difference learning for rare event prediction

no code implementations27 May 2024 Xiaoou Cheng, Jonathan Weare

We quantify the efficiency of temporal difference (TD) learning over the direct, or Monte Carlo (MC), estimator for policy evaluation in reinforcement learning, with an emphasis on estimation of quantities related to rare events.

Improved Active Learning via Dependent Leverage Score Sampling

no code implementations8 Oct 2023 Atsushi Shimizu, Xiaoou Cheng, Christopher Musco, Jonathan Weare

We show how to obtain improved active learning methods in the agnostic (adversarial noise) setting by combining marginal leverage score sampling with non-independent sampling strategies that promote spatial coverage.
