arXiv:2608. 05111v1 Announce Type: new Abstract: In partially observable reinforcement learning, agents face a dual bottleneck: they must explore to encounter rewarding states and retain that experience in memory to optimize their policies.

The paper introduces two algorithms for personalized federated reinforcement learning: PF-UCBVI, which achieves optimal linear speedup by separating shared dynamics from individual goals, and PF-EFVI, a greedy method that uses reward diversity to guarantee state-action coverage without explicit exploration bonuses. The authors prove that PF-EFVI attains logarithmic regret under sufficient reward diversity, showing that disagreement among agents can shift the exploration burden from temporal to spatial aspects. This demonstrates that heterogeneous rewards can be leveraged as a structural asset to facilitate efficient collective learning.
