Understanding Data Drift in Machine Learning Systems
Introduction Understanding data drift in machine learning systems is critical for building reliable and long-lasting AI solutions. When a machine learning model is trained, it learns patterns from historical data. However, real-world data never stays the same. User behavior changes, market conditions shift, and external factors influence incoming data. Data drift occurs when the data used in production becomes different from the data used during training. If this change goes unnoticed, model predictions slowly become inaccurate. In modern AI systems, data drift is one of the main reasons models fail in production. Understanding Data Drift in Machine Learning Systems To understand how data drift impacts deployed models, many engineers begin with MLOps Training , which focuses on monitoring and maintaining real-world ML systems. What Is Data Drift? Data drift happens when the statistical properties of input data change over time. The model itself does not change, ...
