Data Drift vs Concept Drift
Tell apart shifting inputs and shifting targets.
Two Ways the World Shifts
Your model was trained on a snapshot of the past. When reality moves on, it can quietly go stale. There are two distinct ways this happens: data drift and concept drift. 🌍
What Data Drift Means
Data drift happens when the input data changes shape over time. The features your model sees now no longer look like the features it learned from.
