Abstract:
We propose Collective Optimism, a new method for Coordinated Exploration in Distributed Reinforcement Learning. The primary objective of collective optimism is to efficiently coordinate agents' exploration strategies, a concept that has not been previously considered in existing models. This algorithm ensures the maximization of overall performance by taking into account the uncertainty of the current state-action pair, without relying on randomness. A strength of this method is its remarkable ability to be highly applicable to any RL model. To demonstrate the validity of our method and to show its adoptability, we implemented and evaluated the performance of CODRL model through a series of numerical experiments.
