WebNormalizing flow is a transformation process (a network) so that the data in the transformed space has Gaussian distribution. The use case is detecting anomaly in a power grid. RNN is used to... Webmodel normal/anomaly event patterns [16], such as hy-pothesis testing [17], wavelet analysis [18], SVD [19] and ARIMA [20]. Recently, Netflix has released a scalable anomaly detection solution based on robust principal com-ponent analysis [6], which has been proven successful in some real scenarios. Twitter has also published a seasonality-
