A Toolkit for Reliable Benchmarking and Research in Multi-Objective Reinforcement Learning

NeurIPS 2023poster

Multi-objective reinforcement learning algorithms (MORL) extend standard reinforcement learning (RL) to scenarios where agents must optimize multiple---potentially conflicting---objectives, each represented by a distinct reward function. To facilitate and accelerate research and benchmarking in mult…

Multi-Step Generalized Policy Improvement by Leveraging Approximate Models

NeurIPS 2023poster

We introduce a principled method for performing zero-shot transfer in reinforcement learning (RL) by exploiting approximate models of the environment. Zero-shot transfer in RL has been investigated by leveraging methods rooted in generalized policy improvement (GPI) and successor features (SFs). Alt…

Optimistic Linear Support and Successor Features as a Basis for Optimal Policy Transfer

ICML 2022spotlight

In many real-world applications, reinforcement learning (RL) agents might have to solve multiple tasks, each one typically modeled via a reward function. If reward functions are expressed linearly, and the agent has previously learned a set of policies for different tasks, successor features (SFs) c…
