Beyond Independence: Learning Correlated Views for Variational Incomplete Multi-View Clustering

ICML 2026poster

Incomplete multi-view clustering (IMVC) aims to uncover shared cluster structures from data with partially observed views. Although recent imputation-free methods based on variational inference demonstrate robustness to missing views, they commonly rely on a conditional independence assumption acros…

A Hubness Perspective on Representation Learning for Graph-Based Multi-View Clustering

CVPR 2025poster

Recent graph-based multi-view clustering (GMVC) methods typically encode view features into high-dimensional spaces and construct graphs based on distance similarity. However, the high dimensionality of the embeddings often leads to the hubness problem, where a few points repeatedly appear in the ne…

Dynamic Dictionary Learning for Remote Sensing Image Segmentation

ICCV 2025poster

Remote sensing image segmentation faces persistent challenges in distinguishing morphologically similar categories and adapting to diverse scene variations. While existing methods rely on implicit representation learning paradigms, they often fail to dynamically adjust semantic embeddings according…

Generated and Pseudo Content guided Prototype Refinement for Few-shot Point Cloud Segmentation

NeurIPS 2024spotlight

Few-shot 3D point cloud semantic segmentation aims to segment query point clouds with only a few annotated support point clouds. Existing prototype-based methods learn prototypes from the 3D support set to guide the segmentation of query point clouds. However, they encounter the challenge of low pro…

Constrained Confidence Matching for Planar Object Tracking

ICRA 2018poster

Tracking planar objects has a wide range of applications in robotics. Conventional template tracking algorithms, however, often fail to observe fast object motion or drift significantly after a period of time, due to drastic object appearance change. To address such challenges, we propose a novel co…
