FightLadder: A Benchmark for Competitive Multi-Agent Reinforcement Learning

no code implementations4 Jun 2024 Wenzhe Li, Zihan Ding, Seth Karten, Chi Jin

Recent advances in reinforcement learning (RL) heavily rely on a variety of well-designed benchmarks, which provide environmental platforms and consistent criteria to evaluate existing and novel algorithms.

Towards True Lossless Sparse Communication in Multi-Agent Systems

no code implementations30 Nov 2022 Seth Karten, Mycal Tucker, Siva Kailas, Katia Sycara

We evaluate the learned communication `language' through direct causal analysis of messages in non-sparse runs to determine the range of lossless sparse budgets, which allow zero-shot sparsity, and the range of sparse budgets that will inquire a reward loss, which is minimized by our learned gating function with few-shot sparsity.

Probe-Based Interventions for Modifying Agent Behavior

no code implementations26 Jan 2022 Mycal Tucker, William Kuhl, Khizer Shahid, Seth Karten, Katia Sycara, Julie Shah

Neural nets are powerful function approximators, but the behavior of a given neural net, once trained, cannot be easily modified.

Interpretable Learned Emergent Communication for Human-Agent Teams

no code implementations19 Jan 2022 Seth Karten, Mycal Tucker, Huao Li, Siva Kailas, Michael Lewis, Katia Sycara

In human-agent teams tested in benchmark environments, where agents have been modeled using the Enforcers, we find that a prototype-based method produces meaningful discrete tokens that enable human partners to learn agent communication faster and better than a one-hot baseline.
