When ML models are in production, one often needs to keep tabs on the data drift. The goal is to detect changes in the input data distributions to make sure the model still operates in a familiar environment. Applying statistical tests to compare the new data with the old is one way to do it. See more In other words, will the test give a different outcome if we compare datasets of different sizes? Yes, this is statistics! The results will be different when comparing the "same" distributions but taking a sample small or … See more In other words, will the test detect even a "small" change in the data, or does it only respond to a "large" one? In this experiment, we again artificially shifted the feature distribution in … See more We also evaluated whether the statistical tests would react to the drift in one dataset segment.
