 Time series anomaly detection is the process of detecting time-series data outliers; points on a given input time-series where the behavior isn't what was expected, or "weird". These anomalies are typically indicative of some events of interest in the problem domain: a cyber-attack on user accounts, power outage, bursting RPS on a server, memory leak, etc.
 
-To find anomaly on time series, you should first determine the period of the series. Then, the time series can be decomposed into several components as `Y = T + S + R`, where `Y` is the original series, `T` is the trend component, `S` is the seasonal componnent and `R` is the residual component of the series. This step is called [decomposition](https://en.wikipedia.org/wiki/Decomposition_of_time_series). Finally, detection is performed on the residual component to find the anomalies. In ML.NET, The SR-CNN algorithm is an advanced and novel algorithm that is based on Spectral Residual (SR) and Convolutional Neural Network(CNN) to detect anomaly on time-series( Refer to the [Time-Series Anomaly Detection Service at Microsoft](https://arxiv.org/pdf/1906.03821.pdf) paper for more details on this algorithm).
