We are trying to use anomaly detection from Machine Learning. But very little information is available on the internet regarding it. Can you please help us with the following? Details of anomaly detection algorithm, which algorithm is getting used, how does it work etc? 1. Also how is the severity calculated? 2. What are the typical values in the anomalies displayed? 3. Which algorithm gets used for detecting anomalies in univariate time series? Any document throwing light on the above documents will help. ---
