STAIRS-Former: Spatio-Temporal Attention with Interleaved Recursive Structure TransFormer for Offline Mulit-task Multi-agent Reinforcement Learning
ICLR 2026poster
Offline multi-agent reinforcement learning (MARL) with multi-task (MT) datasets poses unique challenges, as input structures vary across tasks due to the varying number of agents. Prior works have adopted transformers and hierarchical skill learning to facilitate coordination, but these methods unde…
