Random Network Distillation
Random Network Distillation (RND) is a technique used to enhance exploration in reinforcement learning by creating an intrinsic reward signal based on the difference between a randomly initialized network's predictions and a learned predictor network's predictions. Current research focuses on improving RND's robustness and effectiveness, addressing issues like unstable reward signals, inefficient exploration, and limitations in representation learning through methods such as pre-training and distributional approaches. These advancements are significant for improving the sample efficiency and performance of reinforcement learning agents in complex, sparse-reward environments, with applications ranging from robotics (e.g., AGV path planning) to data selection for neural network training.
