Chapter 11 – Avoiding and Detecting Data and Concept Drifts
- Magnitude: We might face different magnitudes of difference in the data distribution resulting in drift in our machine learning models. Small changes in the data distribution may be difficult to detect, while large changes may be more noticeable.
Frequency: Drifts might occur in different frequencies.
- The Kolmogorov–Smirnov test can be used for data drift detection.
