Benchmarking the Limits of In-Context Reinforcement Learning for Ad-Hoc Teamwork
The paper explores the limitations of In-Context Reinforcement Learning (ICRL) in the context of Ad-Hoc Teamwork (AHT). A benchmark called ICRL4AHT is introduced to evaluate the performance of various ICRL algorithms in multi-agent settings. Results indicate that these algorithms struggle with test-time adaptation and often perform worse than random baselines.
- ▪The study introduces a benchmark named ICRL4AHT to assess ICRL's effectiveness in AHT scenarios.
- ▪The benchmark includes a diverse suite of teammates and provides a reproducible evaluation pipeline.
- ▪Findings reveal that ICRL algorithms fail to adapt effectively in multi-agent environments, underperforming compared to random strategies.
