Events as Triggers for Behavioral Diversity in Multi-Agent Reinforcement Learning

Read the original on arXiv Machine Learning →

The paper introduces a new multi‑agent reinforcement learning framework that separates agent identity from behavior by using events to trigger behavioral changes. It proposes Neural Manifold Diversity (NMD) to create a continuous behavior manifold and an event‑based hypernetwork that generates Low‑Rank Adaptation (LoRA) modules for on‑the‑fly policy reconfiguration. The authors prove that this design preserves reward maximization and show empirically that it outperforms baselines, generalizes zero‑shot, and uniquely solves tasks requiring sequential behavior reassignment.

Explicit Trajectory Diversity for RL-Based Post-Training of LLM Agents

The paper introduces Trajectory-guided Joint Policy Optimization (TJPO), a reinforcement‑learning framework that explicitly encourages diversity in the trajectories of large‑language‑model agents. By defining task‑specific trajectory descriptors, TJPO measures and optimizes diversity as a set‑level function, avoiding population‑based training. Experiments on Sokoban and ALFWorld demonstrate that TJPO yields diverse, interpretable behaviors while preserving strong task performance.

Out-of-Distribution Generalisation with Sequence Models in Offline Multi-Agent Reinforcement Learning

The paper investigates zero‑shot task generalisation in offline multi‑agent reinforcement learning by extending sequence‑modeling architectures to support multi‑task observation and action spaces and variable agent counts. It finds that increasing task diversity, rather than merely enlarging the dataset, is the key driver for robust zero‑shot transfer. Experiments on four challenging environments show a 3.2× mean improvement on held‑out tasks compared to single‑task models and outperform strong behaviour‑cloning baselines.

Unsupervised Behavioral Compression: Learning Low-Dimensional Policy Manifolds through State-Occupancy Matching

arXiv:2603. 27044v3 Announce Type: replace-cross Abstract: Deep Reinforcement Learning (DRL) is widely recognized as sample-inefficient, a limitation attributable in part to the high dimensionality and substantial functional redundancy inherent to the policy parameter space.
