• MVP introduces a novel approach to incomplete multi-view representation learning by leveraging latent space correspondences in Variational Auto-Encoders, enabling the inference of missing views and enhancing the consistency of multi-view data even with irregularly missing information.

GOOD: Training-Free Guided Diffusion Sampling for Out-of-Distribution Detection

Xin Gao, Jiyao Liu, Guanghao Li, Yueming Lyu, Jianxiong Gao, Weichen Yu, Ningsheng Xu, Liang Wang, Caifeng Shan, Ziwei Liu, Chenyang Si

• GOOD is a training-free diffusion guidance framework that shapes a robust OOD/ID decision boundary. It steers sampling with two gradients—image-level toward low-density regions and feature-level toward sparse zones—to generate diverse, controllable OOD examples.

Dark-ISP: Enhancing RAW Image Processing for Low-Light Object Detection

Jiasheng Guo#, Xin Gao#, Yuxiang Yan, Guanghao Li, Jian Pu

• Dark-ISP is a lightweight, self-adaptive ISP plugin that enhances low-light object detection by processing Bayer RAW images. It breaks down traditional ISP pipelines into optimized linear and nonlinear sub-modules, using physics-informed priors for automatic RAW-to-RGB conversion.

Learning Spatial-Aware Manipulation Ordering

Yuxiang Yan, Zhiyuan Zhou, Xin Gao, Guanghao Li, Shenglin Li, Jiaqi Chen, Qunyan Pu, Jian Pu

• This paper introduces OrderMind, a spatial-aware manipulation ordering framework that learns object priorities from local geometry via a kNN spatial graph and a lightweight temporal module, supervised by VLM-distilled spatial priors. It also presents the Manipulation Ordering Benchmark (163k+ samples) for cluttered scenes.
