Geometry-Preserving Unsupervised Alignment for Heterogeneous Foundation Models

ICML 2026poster

Foundation models have driven rapid progress in computer vision, yet the two dominant paradigm, vision-language foundation models (VLMs) and vision-only foundation models (VFMs), remain only partially compatible. VLMs offer language-grounded semantic alignment but are often visually coarse, while VF…

Hierarchical Prompt Learning for Image- and Text-Based Person Re-Identification

AAAI 2026technical

Person re-identification (ReID) aims to retrieve target pedestrian images given either visual queries (image-to-image, I2I) or textual descriptions (text-to-image, T2I). Although both tasks share a common retrieval objective, they pose distinct challenges: I2I emphasizes discriminative identity lea

SOTA: Self-adaptive Optimal Transport for Zero-Shot Classification with Multiple Foundation Models

CVPR 2026

Foundation models have attracted widespread attention across domains due to their powerful zero-shot classification capabilities. This work is motivated by two key observations: (1) Vision-Language Models (VLMs), such as CLIP, often over-rely on class-level textual priors and struggle to capture fin

[CLS] is Not Enough: Multi-Label Recognition via Patch-Level Inference and Adaptive Aggregation

ICML 2026poster

Vision-Language Models such as CLIP exhibit strong zero-shot recognition capability by aligning images with textual concepts, yet they often underperform on multi-label recognition where multiple objects co-exist. A key bottleneck is that the CLS token, as a single global visual representation, is i…

A Hidden Stumbling Block in Generalized Category Discovery: Distracted Attention

ICCV 2025poster

Generalized Category Discovery (GCD) aims to classify unlabeled data from both known and unknown categories by leveraging knowledge from labeled known categories. While existing methods have made notable progress, they often overlook a hidden stumbling block in GCD: distracted attention. Specificall…
