Two themes have dominated the research on anomaly detection in time series data, one related to explorations of deep architectures for the task, and the other, ...
A Variational Autoencoder, where convolution takes place of dot product, is trained to compress each input to a low-dimensional point from a normal distribution ...
The pattern in the data over time was found using the unsupervised variational autoencoders built using Fully Connected Neural Network and Long Short Term ...
Anomaly detection is a very worthwhile question. However, the anomaly is not a simple two-category in reality, so it is difficult to give accurate results through the comparison of similarities. There are already some deep learning models based on GAN for anomaly detection that demonstrate validity and accuracy on time series data sets. In this paper, we propose an unsupervised model-based ...
30.10.2020 · Two themes have dominated the research on anomaly detection in time series data, one related to explorations of deep architectures for the task, and the other, equally important, the creation of large benchmark datasets. In line with the current trends, we have proposed several deep learning architectures based on Variational Autoencoders that ...

Dec 05, 2021 · Anomaly Detection of Wind Turbine Time Series using Variational Recurrent Autoencoders. Ice accumulation in the blades of wind turbines can cause them to describe anomalous rotations or no rotations at all, thus affecting the generation of electricity and power output. In this work, we investigate the problem of ice accumulation in wind ...
