University of Virginia(弗吉尼亚大学)

Jacob K Christopher, Stephen Baek, Ferdinando Fioretto

AI总结:

本研究提出将扩散模型采样重构为约束优化的投影扩散方法,可在凸、非凸约束及物理场景下生成合规数据,适用于材料合成、运动生成等多领域。

摘要:

本文提出一种方法,赋予生成式扩散过程满足并验证约束与物理原理合规性的能力。该方法将生成式扩散模型的传统采样过程重构为约束优化问题,引导生成的数据分布保持在指定区域内,以确保符合给定约束。研究在包含凸约束与高难度非凸约束、常微分方程的应用中验证了该能力,覆盖领域包括合成具备精确形态计量学特性的新材料、生成符合物理规律的运动、规划场景中的路径优化以及人体运动合成。

英文摘要:

This paper introduces an approach to endow generative diffusion processes the ability to satisfy and certify compliance with constraints and physical principles. The proposed method recast the traditional sampling process of generative diffusion models as a constrained optimization problem, steering the generated data distribution to remain within a specified region to ensure adherence to the given constraints. These capabilities are validated on applications featuring both convex and challenging, non-convex, constraints as well as ordinary differential equations, in domains spanning from synthesizing new materials with precise morphometric properties, generating physics-informed motion, optimizing paths in planning scenarios, and human motion synthesis.
