Concept Drift
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Temporal variability: the meaning or boundaries of a concept change over time. Detection: monitor whether the concept has drifted. Adaptation: adjust the model or understanding to accommodate drift.
SCAFFOLDING EFFECT
Reduce cognitive load
Be wary of the temporal dependence of concepts. A definition that is valid today may become invalid tomorrow. For example, the meaning of "middle class" is constantly changing. Related variants: concept drift, concept drift curve
Anchor fast decisions
Over time, the data distribution or the meaning of the concept changes, causing the original model to fail on new data. The world changes, and models age.
