Attention Based Policy

Attention-based policies are increasingly used in reinforcement learning to improve efficiency and adaptability of agents by focusing on the most relevant information within complex environments. Current research explores various architectures, including continuous-time attention networks for processing irregular time series and distributed morphological attention policies for handling dynamic body morphologies, often incorporating external knowledge or multi-agent interactions. These advancements enhance performance in diverse applications such as simultaneous speech translation, multi-agent collaboration, and robotic control, demonstrating the power of attention mechanisms to guide decision-making in challenging scenarios. The resulting improvements in sample efficiency and generalization capabilities are significant contributions to the field of reinforcement learning.
