Risk-Averse Total-Reward Reinforcement Learning

Xihong Su, Jia Lin Hau, Gersi Doko +2

Risk-averse total-reward Markov Decision Processes (MDPs) offer a promising framework for modeling and solving undiscounted infinite-horizon objectives. Existing model-based algori…

Efficient Algorithms for Mitigating Uncertainty and Risk in Reinforcement Learning

Xihong Su

This dissertation makes three main contributions. First, We identify a new connection between policy gradient and dynamic programming in MMDPs and propose the Coordinate Ascent Dyn…

Risk-averse Total-reward MDPs with ERM and EVaR

Xihong Su, Julien Grand-Clément, Marek Petrik

Optimizing risk-averse objectives in discounted MDPs is challenging because most models do not admit direct dynamic programming equations and require complex history-dependent poli…
