Anomaly detection is a method used to detect something that doesn’t fit the normal behavior of a dataset. In other words, anomaly detection finds data points in a dataset that deviates from the rest of the data. Those unusual things are called outliers, peculiarities, exceptions, surprise and etc. For example: Anomaly detection is a technique used in data analysis to identify patterns that deviate significantly from expected behavior.
