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.

ARDIR: Improving Robustness using Knowledge Distillation of Internal Representation

no code implementations1 Nov 2022 Tomokatsu Takahashi, Masanori Yamada, Yuuki Yamanaka, Tomoya Yamashita

In addition to the output of the teacher model, ARDIR uses the internal representation of the teacher model as a label for adversarial training.

Adversarial Training Makes Weight Loss Landscape Sharper in Logistic Regression

no code implementations5 Feb 2021 Masanori Yamada, Sekitoshi Kanai, Tomoharu Iwata, Tomokatsu Takahashi, Yuki Yamanaka, Hiroshi Takahashi, Atsutoshi Kumagai

We theoretically and experimentally confirm that the weight loss landscape becomes sharper as the magnitude of the noise of adversarial training increases in the linear logistic regression model.
