Summary

This paper introduces EDPFRL-IM, an exploration-driven personalized federated reinforcement learning framework that uses intrinsic motivation at each client to promote local exploration and protect privacy. By adding an intrinsic random network distillation signal to extrinsic rewards and sharing minimal novelty summaries, the framework achieves better policy personalization and sample efficiency, especially in sparse-reward environments.

Personalized Federated Reinforcement Learning (PFRL) aims to train individualized policies across multiple clients while keeping their data private. Existing PFRL methods often prioritize exploiting known reward signals, neglecting the crucial aspect of exploration, especially in environments where rewards are sparse or change over time. This new framework, called Exploration-Driven Personalized Federated Reinforcement Learning via Intrinsic Motivation (EDPFRL-IM), addresses this limitation.EDPFRL-IM integrates a curiosity-driven exploration mechanism at each client, enhancing local exploration and maintaining data privacy. Clients augment their standard rewards with an intrinsic signal derived from random network distillation (RND), which encourages them to explore novel state spaces. The central server facilitates coordinated exploration by exchanging global exploration priors and minimal novelty summaries, rather than raw data or gradients. Experiments show that EDPFRL-IM significantly outperforms traditional PFRL benchmarks in terms of policy personalization and sample efficiency, particularly in challenging delayed and sparse reward scenarios.

Why it matters

For organizations dealing with decentralized data and privacy concerns, this framework offers a way to develop more effective and personalized AI agents that can learn efficiently even in complex, unknown environments.

How to implement this in your domain
