Data drift refers to the phenomenon where the distribution of live, real-world data differs or “drifts” from the distribution of data used to train a machine learning model. When data drift occurs, the performance of machine learning models in production degrades, resulting in inaccurate predictions. This reduction in the model’s predictive power can adversely impact the expected business value from the investment in training. If data drift is not identified in time, the machine learning model may become stale and eventually useless.
In this article, you’ll learn more about data drift, exploring why and in what ways it occurs, its impact, and how it can be mitigated and prevented.
