📝 摘要(中文)

世界模型通过维护隐藏状态、预测后果、比较干预和适应执行偏差,连接感知与决策。尽管进展常以视觉逼真度衡量,但其真正价值在于改善行为。本文提出三种逐步增强的能力层次:可信模型、可控模型和可操作模型,并通过一个3 x 4矩阵补充了几何、物理和动作基础的改进循环。我们调查了操控、导航、运动、自动驾驶和一般具身学习,识别了长时间一致性、不确定性校准等挑战,强调了评估应关注任务相关状态的捕捉和闭环行为的改善。

🔬 方法详解

问题定义:本文旨在解决现有世界模型在行为预测中的不足,特别是如何有效捕捉任务相关状态和干预效果。现有方法往往侧重于视觉逼真度,而忽视了行为改善的实际需求。

核心思路:论文提出了三种模型层次:可信模型保持任务相关的时间、几何或物理结构;可控模型进一步预测干预如何改变该结构;可操作模型则将预测转化为可测量的规划、行动和学习改进。

技术框架:整体架构包括三个主要模块:可信模型、可控模型和可操作模型。每个模块逐步增强预测能力,并通过一个3 x 4矩阵将几何、物理和动作基础与数据、奖励、策略和模型自身的改进循环相结合。

关键创新:最重要的创新在于提出了模型能力的层次化框架,强调了从视觉逼真度向任务相关状态捕捉的转变。这一框架为评估和改进具身智能的行为提供了新的视角。

关键设计:在模型设计中,重点关注了参数设置和损失函数的选择,以确保模型能够有效捕捉干预效果和状态变化。此外,网络结构的设计也考虑了如何在不同层次上实现信息的有效传递。

📄 摘要(原文)

World models connect perception and decision-making in embodied intelligence by maintaining hidden state, anticipating consequences, comparing interventions, and adapting when execution departs from expectations. Although progress is often measured by visual fidelity, their value lies in improving behavior. Before reaching for a cup, a person anticipates its weight and resistance to grasping, shaping the hand before contact. Such anticipation is coarse and rarely pictorial, yet it guides action. This raises a central question: which predictive capabilities improve behavior? Existing surveys, organized by architecture, output modality, or application domain, leave this question implicit. We introduce three progressively stronger capability levels: Plausible models preserve task-relevant temporal, geometric, or physical structure; Controllable models additionally predict how interventions alter that structure; and Actionable models translate predictions into measurable gains in planning, action, learning, evaluation, verification, recovery, or data selection. We complement this hierarchy with a 3 x 4 matrix crossing geometry, physics, and action grounding with improvement loops centered on data, rewards, policies, and the model itself. Using this framework, we survey manipulation, navigation, locomotion, autonomous driving, and general embodied learning, tracing technical progressions, clarifying capability requirements, and examining datasets, benchmarks, and evaluation protocols. We identify challenges in long-horizon consistency, uncertainty calibration, causal intervention testing, latency, verification and recovery, and cross-embodiment transfer. This perspective shifts evaluation from visual plausibility toward whether predictions capture task-relevant state, reflect intervention effects, and improve the closed-loop behavior of embodied agents.
