心智世界建模：将心智变量纳入世界模型核心

AI 摘要

该论文提出心智世界建模（MWM）框架，将心智变量作为世界模型的核心组成部分，而非事后解释。作者在MENTIS基线中实现了该框架，通过显式分解状态解析、目标观察生成、动作分解等阶段，在文本、图像和视频故事数据集上验证了显式建模心智状态对预测人类决策的必要性。实验表明，完整MWM在所有评估模型上表现最佳，而移除心智通道会降低性能，最大的瓶颈在于转换模拟。

Mental World Modeling Abstract World models enable a predictive substrate for planning and action, yet existing formulations merely answer a physical question: what/where it is, and how will it evolve. Human behavior, however, is driven by hidden mental state (what a person believes, wants, intends, feels, and considers socially permissible), so a model that tracks the physical scene but not what each agent knows and believes about it predicts the wrong action for the right-looking scene.
