Developing an Unsupervised Real-time Anomaly Detection Scheme for Time Series with Multi-seasonality

no code implementations3 Aug 2019 Wentai Wu, Ligang He, Weiwei Lin, Yi Su, Yuhua Cui, Carsten Maple, Stephen Jarvis

In light of this, we have developed a prediction-driven, unsupervised anomaly detection scheme, which adopts a backbone model combining the decomposition and the inference of time series data.
