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…

Learning Intrinsic Hierarchy for Generalized Category Discovery

AAAI 2026technical

Generalized Category Discovery (GCD) aims to classify unlabeled data by leveraging knowledge from labeled categories. While existing methods have achieved remarkable progress, they often treat images as flat feature sets, neglecting the intrinsic hierarchy: where key objects dominate meaning and bac

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…

Catalyst for Clustering-Based Unsupervised Object Re-identification: Feature Calibration

AAAI 2024technical

Clustering-based methods are emerging as a ubiquitous technology in unsupervised object Re-Identification (ReID), which alternate between pseudo-label generation and representation learning. Recent advances in this field mainly fall into two groups: pseudo-label correction and robust representation…
