Efficient Reinforcement Learning
Efficient reinforcement learning (RL) aims to accelerate the training of RL agents by reducing the computational cost and data requirements, enabling application to complex real-world problems. Current research focuses on improving sample efficiency through techniques like reward shaping with large language models, physics-informed models, action space reduction, and leveraging offline datasets or expert demonstrations. These advancements, often implemented using model-based RL, policy gradient methods, or actor-critic architectures, are crucial for deploying RL in resource-constrained settings and high-dimensional problems such as robotics and autonomous driving, ultimately bridging the gap between theoretical advancements and practical applications.
