Zero-shot domain adaptation of anomalous samples for semi-supervised anomaly detection

no code implementations5 Apr 2023 Tomoya Nishida, Takashi Endo, Yohei Kawaguchi

To solve this problem, we propose a domain adaptation method for SSAD where no anomalous data are available for the target domain.

Anomalous Sound Detection Based on Machine Activity Detection

no code implementations15 Apr 2022 Tomoya Nishida, Kota Dohi, Takashi Endo, Masaaki Yamamoto, Yohei Kawaguchi

We have developed an unsupervised anomalous sound detection method for machine condition monitoring that utilizes an auxiliary task -- detecting when the target machine is active.

Disentangling Physical Parameters for Anomalous Sound Detection Under Domain Shifts

no code implementations12 Nov 2021 Kota Dohi, Takashi Endo, Yohei Kawaguchi

To solve this problem, the proposed method constrains some latent variables of a normalizing flows (NF) model to represent physical parameters, which enables disentanglement of the factors of domain shifts and learning of a latent space that is invariant with respect to these domain shifts.

Anomalous sound detection based on interpolation deep neural network

1 code implementation19 May 2020 Kaori Suefusa, Tomoya Nishida, Harsh Purohit, Ryo Tanabe, Takashi Endo, Yohei Kawaguchi

However, when the target machine sound is non-stationary, a reconstruction error tends to be large independent of an anomaly, and its variations increased because of the difficulty of predicting the edge frames.

MIMII Dataset: Sound Dataset for Malfunctioning Industrial Machine Investigation and Inspection

5 code implementations20 Sep 2019 Harsh Purohit, Ryo Tanabe, Kenji Ichige, Takashi Endo, Yuki Nikaido, Kaori Suefusa, Yohei Kawaguchi

The purpose of releasing the MIMII dataset is to assist the machine-learning and signal-processing community with their development of automated facility maintenance.
