Abstract
Methods and systems are described herein for determining data shifts using change point detection in time series datasets. The system receives, from a change point modelling system, a first model and a plurality of change points detected within a time series dataset using the first model. The system generates, for each change point, a second corresponding model that fails to detect a corresponding change point and inputs the time series dataset into the first model and into each second corresponding model. The system determines a performance difference between the first model and each second corresponding model and assigns severity metrics to the change points based on the corresponding performance difference. The system selects a subset of change points based on the severity metrics and determines a cause of each change point of the subset of change points.
