VEQ: Modality-Adaptive Quantization for MoE Vision-Language Models

ICML 2026poster

Mixture-of-Experts(MoE) Vision-Language Models(VLMs) offer remarkable performance but incur prohibitive memory and computational costs, making compression essential. Post-Training Quantization (PTQ) is an effective training-free technique to address the massive memory and computation overhead. Exist…

Dinomaly: The Less Is More Philosophy in Multi-Class Unsupervised Anomaly Detection

CVPR 2025poster

Recent studies highlighted a practical setting of unsupervised anomaly detection (UAD) that builds a unified model for multi-class images. Despite various advancements addressing this challenging task, the detection performance under the multi-class setting still lags far behind state-of-the-art cla…

A Physics-informed Low-rank Deep Neural Network for Blind and Universal Lens Aberration Correction

CVPR 2024poster

High-end lenses although offering high-quality images suffer from both insufficient affordability and bulky design which hamper their applications in low-budget scenarios or on low-payload platforms. A flexible scheme is to tackle the optical aberration of low-end lenses computationally. However it…

ReContrast: Domain-Specific Anomaly Detection via Contrastive Reconstruction

NeurIPS 2023poster

Most advanced unsupervised anomaly detection (UAD) methods rely on modeling feature representations of frozen encoder networks pre-trained on large-scale datasets, e.g. ImageNet. However, the features extracted from the encoders that are borrowed from natural image domains coincide little with the f…

Universal and Flexible Optical Aberration Correction Using Deep-Prior Based Deconvolution

ICCV 2021poster

High quality imaging usually requires bulky and expensive lenses to compensate geometric and chromatic aberrations. This poses high constraints on the optical hash or low cost applications. Although one can utilize algorithmic reconstruction to remove the artifacts of low-end lenses, the degeneratio…
