Researchers have developed a new reinforcement learning algorithm called D2 Actor Critic (D2AC) designed to train diffusion policies more effectively. This algorithm utilizes a stable policy improvement objective that avoids high variance and the complexity of backpropagation through time. A key component is a robust distributional critic, which combines distributional RL with clipped double Q-learning, leading to state-of-the-art performance on eighteen challenging RL tasks. AI
