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

2 code implementations Conference on Neural Information Processing Systems Datasets and Benchmarks Track 2023 Florian Felten, Lucas N. Alegre, Ann Nowé, Ana L. C. Bazzan, El-Ghazali Talbi, Grégoire Danoy, Bruno C. da Silva

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.

Sample-Efficient Multi-Objective Learning via Generalized Policy Improvement Prioritization

2 code implementations18 Jan 2023 Lucas N. Alegre, Ana L. C. Bazzan, Diederik M. Roijers, Ann Nowé, Bruno C. da Silva

Finally, we introduce a bound that characterizes the maximum utility loss (with respect to the optimal solution) incurred by the partial solutions computed by our method throughout learning.

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

1 code implementation22 Jun 2022 Lucas N. Alegre, Ana L. C. Bazzan, Bruno C. da Silva

If reward functions are expressed linearly, and the agent has previously learned a set of policies for different tasks, successor features (SFs) can be exploited to combine such policies and identify reasonable solutions for new problems.

Quantifying the Impact of Non-Stationarity in Reinforcement Learning-Based Traffic Signal Control

no code implementations9 Apr 2020 Lucas N. Alegre, Ana L. C. Bazzan, Bruno C. da Silva

In this paper we analyze the effects that different sources of non-stationarity have in a network of traffic signals, in which each signal is modeled as a learning agent.
