Absolute-Unified Multi-Class Anomaly Detection via Class-Agnostic Distribution Alignment

no code implementations31 Mar 2024 Jia Guo, Haonan Han, Shuai Lu, Weihang Zhang, Huiqi Li

We propose Class-Agnostic Distribution Alignment (CADA) to align the mismatched score distribution of each implicit class without knowing class information, which enables unified anomaly detection for all classes and samples.

ReContrast: Domain-Specific Anomaly Detection via Contrastive Reconstruction

1 code implementation NeurIPS 2023 Jia Guo, Shuai Lu, Lize Jia, Weihang Zhang, Huiqi Li

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.
