Select to Perfect: Imitating desired behavior from large multi-agent data

no code implementations6 May 2024 Tim Franzmeyer, Edith Elkind, Philip Torr, Jakob Foerster, Joao Henriques

Desired characteristics for an AI agent can be expressed by assigning desirability scores, which we assume are not assigned to individual behaviors but to collective trajectories.

Rethinking Out-of-Distribution Detection for Reinforcement Learning: Advancing Methods for Evaluation and Detection

2 code implementations10 Apr 2024 Linas Nasvytis, Kai Sandbrink, Jakob Foerster, Tim Franzmeyer, Christian Schroeder de Witt

In this paper, we study the problem of out-of-distribution (OOD) detection in RL, which focuses on identifying situations at test time that RL agents have not encountered in their training environments.

Extracting Reward Functions from Diffusion Models

1 code implementation NeurIPS 2023 Felipe Nuti, Tim Franzmeyer, João F. Henriques

Diffusion models have achieved remarkable results in image generation, and have similarly been used to learn high-performing policies in sequential decision-making tasks.

Learn what matters: cross-domain imitation learning with task-relevant embeddings

no code implementations24 Sep 2022 Tim Franzmeyer, Philip H. S. Torr, João F. Henriques

We study how an autonomous agent learns to perform a task from demonstrations in a different domain, such as a different environment or different agent.
