FastRef: Fast Prototype Refinement for Few-shot Industrial Anomaly Detection

CVPR 2026

Few-shot industrial anomaly detection (FS-IAD) presents a critical challenge for practical automated inspection systems operating in data-scarce environments. While existing approaches predominantly focus on obtaining prototypes from limited normal images, they neglect to systematically incorporate

Foreground-aware Prototypical Network for Prohibited Item Detection from X-ray Scans

ICASSP 2025accepted

Automatic inspection of X-ray scans is a critical component of modern safety protocols. It plays an indispensable role in detecting concealed weapons, explosives, and other prohibited items that could pose a threat to public safety. Current surveillance systems perform poorly without human intervent…

Improving Data Annotation for Low-Resource Relation Extraction with Logical Rule-Augmented Collaborative Language Models

NAACL 2025long

Low-resource relation extraction aims to identify semantic relationships between entities using scarce labeled data. Recent studies exploit large language models to recognize relations based on retrieved examplars, yielding promising results. However, the reliability of predictions from these method…

Hierarchical Vector Quantized Transformer for Multi-class Unsupervised Anomaly Detection

NeurIPS 2023poster

Unsupervised image Anomaly Detection (UAD) aims to learn robust and discriminative representations of normal samples. While separate solutions per class endow expensive computation and limited generalizability, this paper focuses on building a unified framework for multiple classes. Under such a cha…

Label Robust and Differentially Private Linear Regression: Computational and Statistical Efficiency

NeurIPS 2023poster

We study the canonical problem of linear regression under $(\varepsilon,\delta)$-differential privacy when the datapoints are sampled i.i.d.~from a distribution and a fraction of response variables are adversarially corrupted. We provide the first provably efficient -- both computationally and stati…

Prototypes-oriented Transductive Few-shot Learning with Conditional Transport

ICCV 2023poster

Transductive Few-Shot Learning (TFSL) has recently attracted increasing attention since it typically outperforms its inductive peer by leveraging statistics of query samples.However, previous TFSL methods usually encode uniform prior that all the classes within query samples are equally likely, whic…

LightPose: A Lightweight and Efficient Model with Transformer for Human Pose Estimation

ICASSP 2022accepted

The prediction of keypoints by generating high-resolution heatmaps has become a popular solution in human pose estimation. While this kind of method requires up-sampling or deconvolution operations, which would bring a great challenge to the acceleration of model inference. If performing keypoint pr…

Robust and differentially private mean estimation

NeurIPS 2021poster

In statistical learning and analysis from shared data, which is increasingly widely adopted in platforms such as federated learning and meta-learning, there are two major concerns: privacy and robustness. Each participating individual should be able to contribute without the fear of leaking one's se…

Adaptive Mixture Regression Network with Local Counting Map for Crowd Counting

ECCV 2020poster

The crowd counting task aims at estimating the number of people located in an image or a frame from videos. Existing methods widely adopt density maps as the training targets to optimize the point-to-point loss. While in testing phase, we only focus on the differences between the crowd numbers and t…

Minimax Optimal Estimation of Approximate Differential Privacy on Neighboring Databases

NeurIPS 2019poster

Differential privacy has become a widely accepted notion of privacy, leading to the introduction and deployment of numerous privatization mechanisms. However, ensuring the privacy guarantee is an error-prone process, both in designing mechanisms and in implementing those mechanisms. Both types of er…
