Subspace-Guided Feature Reconstruction for Unsupervised Anomaly Localization

no code implementations25 Sep 2023 Katsuya Hotta, Chao Zhang, Yoshihiro Hagihara, Takuya Akashi

In this paper, we propose a novel subspace-guided feature reconstruction framework to pursue adaptive feature approximation for anomaly localization.

PMSSC: Parallelizable multi-subset based self-expressive model for subspace clustering

no code implementations24 Nov 2021 Katsuya Hotta, Takuya Akashi, Shogo Tokai, Chao Zhang

Subspace clustering methods which embrace a self-expressive model that represents each data point as a linear combination of other data points in the dataset provide powerful unsupervised learning techniques.
