Hunting Normality from Query Sample via Residual Learning for Generalist Anomaly Detection

CVPR 2026

Generalist Anomaly Detection (GAD) seeks to overcome the domain-specific limitations of traditional anomaly detection by training a unified model that can generalize to unseen classes. A promising GAD strategy involves using residual features to create a class-invariant space. However, existing meth

Unifying Reconstruction and Density Estimation via Invertible Contraction Mapping in One-Class Classification

NeurIPS 2025poster

Due to the difficulty in collecting all unexpected abnormal patterns, One-Class Classification (OCC) has become the most popular approach to anomaly detection (AD). Reconstruction-based AD method relies on the discrepancy between inputs and reconstructed results to identify unobserved anomalies. How…

Image Augmentation with Controlled Diffusion for Weakly-Supervised Semantic Segmentation

ICASSP 2024accepted

Weakly-supervised semantic segmentation (WSSS), which aims to train segmentation models solely using image-level labels, has achieved significant attention. Existing methods primarily focus on generating high-quality pseudo labels using available images and their image-level labels. However, the qua…

PSDPM: Prototype-based Secondary Discriminative Pixels Mining for Weakly Supervised Semantic Segmentation

CVPR 2024poster

Image-level Weakly Supervised Semantic Segmentation (WSSS) has received increasing attention due to its low annotation cost. Class Activation Mapping (CAM) generated through classifier weights in WSSS inevitably ignores certain useful cues while the CAM generated through class prototypes can allevia…

Learning to Solve Tasks with Exploring Prior Behaviours

IROS 2023poster

Demonstrations are widely used in Deep Reinforcement Learning (DRL) for facilitating solving tasks with sparse rewards. However, the tasks in real-world scenarios can often have varied initial conditions from the demonstration, which would require additional prior behaviours. For example, consider w…

Gated Multi-Layer Convolutional Feature Extraction Network for Robust Pedestrian Detection

ICASSP 2020accepted

Pedestrian detection methods have been significantly improved with the development of deep convolutional neural networks. Nevertheless, it remains a challenging problem how to robustly detect pedestrians of varied sizes and with occlusions. In this paper, we propose a gated multi-layer convolutional…

LIIR: Learning Individual Intrinsic Reward in Multi-Agent Reinforcement Learning

NeurIPS 2019poster

A great challenge in cooperative decentralized multi-agent reinforcement learning (MARL) is generating diversified behaviors for each individual agent when receiving only a team reward. Prior studies have paid much effort on reward shaping or designing a centralized critic that can discriminatively…
