Anomaly Detection for Multivariate Time Series on Large-scale Fluid Handling Plant Using Two-stage Autoencoder

no code implementations20 May 2022 Susumu Naito, Yasunori Taguchi, Kouta Nakata, Yuichi Kato

This paper focuses on anomaly detection for multivariate time series data in large-scale fluid handling plants with dynamic components, such as power generation, water treatment, and chemical plants, where signals from various physical phenomena are observed simultaneously.

RDEC: Integrating Regularization into Deep Embedded Clustering for Imbalanced Datasets

no code implementations6 Dec 2018 Yaling Tao, Kentaro Takagi, Kouta Nakata

DEC optimizes cluster assignments by pushing data more densely around centroids in latent space, but it is sometimes sensitive to the initial location of centroids, especially in the case of imbalanced data, where the minor class has less chance to be assigned a good centroid.
