Cross-Domain Few-Shot Learning via Multi-View Collaborative Optimization with Vision-Language Models

AAAI 2026technical

Vision-language models (VLMs) pre-trained on natural image and language data, such as CLIP, have exhibited significant potential in few-shot image recognition tasks, leading to development of various efficient transfer learning methods. These methods exploit inherent pre-learned knowledge in VLMs an

DCAC: Dynamic Class-Aware Cache Creates Stronger Out-of-Distribution Detectors

AAAI 2026technical

Out-of-distribution (OOD) detection remains a fundamental challenge for deep neural networks, particularly due to overconfident predictions on unseen OOD samples during testing. We reveal a key insight: OOD samples predicted as the same class, or given high probabilities for it, are visually more si

Decoupling Continual Semantic Segmentation

AAAI 2026technical

Continual Semantic Segmentation (CSS) requires learning new classes without forgetting previously acquired knowledge, addressing the fundamental challenge of catastrophic forgetting in dense prediction tasks. However, existing CSS methods typically employ single-stage encoder-decoder architectures w

TTL: Test-time Textual Learning for OOD Detection with Pretrained Vision-Language Models

CVPR 2026

Vision-language models (VLMs) such as CLIP exhibit strong Out-of-distribution (OOD) detection capabilities by aligning visual and textual representations. Recent CLIP-based test-time adaptation methods further improve detection performance by incorporating external OOD labels. However, such labels a

Conditional Visual Autoregressive Modeling for Pathological Image Restoration

ICCV 2025poster

Pathological image has been recognized as the gold standard for cancer diagnosis for more than a century. However, some internal regions of pathological images may inevitably exhibit various degradation issues, including low resolution, image blurring, and image noising, which will affect disease di…

FA: Forced Prompt Learning of Vision-Language Models for Out-of-Distribution Detection

ICCV 2025poster

Pre-trained vision-language models (VLMs) have advanced out-of-distribution (OOD) detection recently. However, existing CLIP-based methods often focus on learning OOD-related knowledge to improve OOD detection, showing limited generalization or reliance on external large-scale auxiliary datasets. In…

Audio-Aided Learning Framework for Image Classification with Limited Training Images

ICASSP 2024accepted

It is challenging to train a generalizable deep learning classifier with limited training images. Existing few-shot learning approaches try to improve classification performance largely by transferring prior knowledge from upstream large-sample tasks to the current small-sample task. Besides upstrea…

Exploiting Discrepancy in Feature Statistic for Out-of-Distribution Detection

AAAI 2024technical

Recent studies on out-of-distribution (OOD) detection focus on designing models or scoring functions that can effectively distinguish between unseen OOD data and in-distribution (ID) data. In this paper, we propose a simple yet novel ap- proach to OOD detection by leveraging the phenomenon that the…

FeatWalk: Enhancing Few-Shot Classification through Local View Leveraging

AAAI 2024technical

Few-shot learning is a challenging task due to the limited availability of training samples. Recent few-shot learning studies with meta-learning and simple transfer learning methods have achieved promising performance. However, the feature extractor pre-trained with the upstream dataset may neglect…

TagFog: Textual Anchor Guidance and Fake Outlier Generation for Visual Out-of-Distribution Detection

AAAI 2024technical

Out-of-distribution (OOD) detection is crucial in many real-world applications. However, intelligent models are often trained solely on in-distribution (ID) data, leading to overconfidence when misclassifying OOD data as ID classes. In this study, we propose a new learning framework which leverage…

Revisit PCA-based Technique for Out-of-Distribution Detection

ICCV 2023poster

Out-of-distribution (OOD) detection is a desired ability to ensure the reliability and safety of intelligent systems. A scoring function is often designed to measure the degree of any new data being an OOD sample. While most designed scoring functions are based on a single source of information (e.g…
