中文摘要
本文提出DreamerAD，首个潜在世界模型框架，通过将扩散采样从100步压缩到1步，实现80倍加速同时保持视觉可解释性，从而支持高效的自动驾驶强化学习。在真实驾驶数据上训练RL策略会产生高昂的成本和安全风险。虽然现有的像素级扩散世界模型支持安全的基于想象的训练，但它们遭受多步扩散推理延迟（2秒/帧）的困扰，阻碍了高频RL交互。
原文摘要
We introduce DreamerAD, the first latent world model framework that enables efficient reinforcement learning for autonomous driving by compressing diffusion sampling from 100 steps to 1 - achieving 80x speedup while maintaining visual interpretability. Training RL policies on real-world driving data incurs prohibitive costs and safety risks. While existing pixel-level diffusion world models enable safe imagination-based training, they suffer from multi-step diffusion inference latency (2s/frame) that prevents high-frequency RL interaction.
