Proxy Experience Replay: Federated Distillation for Distributed Reinforcement Learning

Han Cha, Jihong Park, Hyesung Kim +2

Traditional distributed deep reinforcement learning (RL) commonly relies on exchanging the experience replay memory (RM) of each agent. Since the RM contains all state observations…

Demo: A Reinforcement Learning-based Flexible Duplex System for B5G with Sub-6 GHz

Soo-Min Kim, Han Cha, Seong-Lyun Kim +1

In this paper, we propose a reinforcement learning-based flexible duplex system for B5G with Sub-6 GHz. This system combines full-duplex radios and dynamic spectrum access to maxim…

Federated Reinforcement Distillation with Proxy Experience Memory

Han Cha, Jihong Park, Hyesung Kim +2

In distributed reinforcement learning, it is common to exchange the experience memory of each agent and thereby collectively train their local models. The experience memory, howeve…
