unsupervised anomaly detection (UAD) is a key data mining problem owing to
its wide real-world applications. Due to the complete absence of supervision
signals, UAD methods rely on implicit assumptions about anomalous patterns
(e.g., scattered/sparsely/densely clustered) to detect anom
本文提出了一种用于多类异常检测的无类别信息的绝对统一的方法,通过类别不可用的条件下,利用 Class-Agnostic Distribution Alignment (CADA) 对于不同类别的异常分数分布进行匹配,实现了统一检测方法, 在 MVTec AD 和 VisA 等 UAD 基准数据集上超过了之前的最先进方法。
