Active Learning with Foundation Model Priors: Efficient Learning under Class Imbalance

ICML 2026poster

Real-world datasets across image and text domains are often characterized by skewed class distributions and noisy annotations, which jointly degrade model performance, particularly on minority classes. Among existing solutions, active learning offers an effective and efficient paradigm by selectivel…

Test-Time Matching: Unlocking Compositional Reasoning in Multimodal Models

ICLR 2026poster

Multimodal models have achieved remarkable progress, yet recent studies suggest they struggle with compositional reasoning, often performing at or below random chance on established benchmarks. We revisit this problem and show that widely used evaluation metrics systematically underestimate model ca…

Dual Prior Unfolding for Snapshot Compressive Imaging

CVPR 2024poster

Recently deep unfolding methods have achieved remarkable success in the realm of Snapshot Compressive Imaging (SCI) reconstruction. However the existing methods all follow the iterative framework of a single image prior which limits the efficiency of the unfolding methods and makes it a problem to u…

Improving Spectral Snapshot Reconstruction with Spectral-Spatial Rectification

CVPR 2024poster

How to effectively utilize the spectral and spatial characteristics of Hyperspectral Image (HSI) is always a key problem in spectral snapshot reconstruction. Recently the spectra-wise transformer has shown great potential in capturing inter-spectra similarities of HSI but the classic design of the t…
