COOP: Defining, Observing, and Repairing Cooperation in LLM Multi-Agent Systems

Hanqing Yang, Narjes Nourzad, Shiyu Chen +3

Many complex tasks require extended effort, diverse capabilities, or coordinated actions beyond what a single agent can provide. However, simply adding more agents does not guarant…

FIRE: A Failure-Adaptive Reinforcement Learning Framework for Edge Computing Migrations

Marie Siew, Shikhar Sharma, Zekai Li +5

In edge computing, users' service profiles are migrated due to user mobility. Reinforcement learning (RL) frameworks have been proposed to do so, often trained on simulated data. H…

Fair Concurrent Training of Multiple Models in Federated Learning

Marie Siew, Haoran Zhang, Jong-Ik Park +6

Federated learning (FL) enables collaborative learning across multiple clients. In most FL work, all clients train a single learning task. However, the recent proliferation of FL a…
