Disentangling 3D Modeling from Spatial Reasoning

Haoze Sun, Jiequan Cui, Qingshan Xu +1

In this work, we explore an alternative paradigm for spatial reasoning by explicitly disentangling 3D perception from reasoning, rather than jointly acquiring implicit 3D perceptio…

Visual Token Compression Enhances Robustness of MLLMs

Shishen Gu, Jiequan Cui, Wenbo Hu +3

In this paper, we show for the first time that visual token pruning enhances the robustness of Multimodal Large Language Models (MLLMs), mitigating vulnerabilities such as jailbrea…

Class-frequency Guided Noise Schedule for Diffusion Models

Jiequan Cui, Beier Zhu, Qingshan Xu +3

In this paper, we are the first to examine the correlations between class frequency and the multi-scale noise schedule within diffusion models. For score-based generative models, l…

NeuSpring: Neural Spring Fields for Reconstruction and Simulation of Deformable Objects from Videos

Qingshan Xu, Jiao Liu, Shangshu Yu +6

In this paper, we aim to create physical digital twins of deformable objects under interaction. Existing methods focus more on the physical learning of current state modeling, but…
