In this paper, in order to discover the abnormal information in the QAR data, we applied a VAE-LSTM model with a multihead self-attention mechanism. Compared to the VAE and LSTM models alone, our model performs much better in anomaly detection and prediction, detecting al...
After the model has been trained, we also prepare an iPython-notebook in NAB-anomaly-detection.ipynb for you to detect some anomalies detection on the test set. All you need to do is to run the code, make sure the NAB_config.json is prepared so that the right trained model will be ...
Anomaly detection using the trained model After the model has been trained, we also prepare an iPython-notebook in NAB-anomaly-detection.ipynb for you to detect some anomalies detection on the test set. All you need to do is to run the code, make sure the NAB_config.json is prepared so...
In this work, we propose a VAE-LSTM hybrid model as an unsupervised approach for anomaly detection in time series. Our model utilizes both a VAE module for forming robust local features over short windows and a LSTM module for estimating the long term correlation in the series on top of the...
Time series anomaly detection is widely used to monitor the equipment sates through the data collected in the form of time series. At present, the deep learning method based on generative adversarial networks (GAN) has emerged for time series anomaly detection. However, this method needs to find...
