Deep Positive-Unlabeled Anomaly Detection for Contaminated Unlabeled Data

1 code implementation29 May 2024 Hiroshi Takahashi, Tomoharu Iwata, Atsutoshi Kumagai, Yuuki Yamanaka

With our approach, we can approximate the anomaly scores for normal data using the unlabeled and anomaly data.

LogELECTRA: Self-supervised Anomaly Detection for Unstructured Logs

no code implementations16 Feb 2024 Yuuki Yamanaka, Tomokatsu Takahashi, Takuya Minami, Yoshiaki Nakajima

In this paper, we propose LogELECTRA, a new log anomaly detection model that analyzes a single line of log messages more deeply on the basis of self-supervised anomaly detection.
