Coupled-hypersphere-based
WebDec 8, 2024 · Anomaly detection is a well-established research area that seeks to identify samples outside of a predetermined distribution. An anomaly detection pipeline is comprised of two main stages: (1) feature extraction and (2) normality score assignment. Recent papers used pre-trained networks for feature extraction achieving state-of-the-art results. WebCFA: Coupled-hypersphere-based Feature Adaptation for Target-Oriented Anomaly Localization. 1 code implementation • 9 Jun 2024 • Sungwook Lee, SeungHyun Lee , Byung Cheol Song. In addition, this paper points out the negative effects of biased features of pre-trained CNNs and emphasizes the importance of the adaptation to the target dataset. ...
