Merono-Penuela, A. et al. Extensional Concept Drift
MotivationStability of Meaning of Concepts
As the world changes continuously, concepts also change theirmeaning over time. We call this concept drift
We call this concept drift
Smooth transitions
Radical transitions (concept shift)
Merono-Penuela, A. et al. Extensional Concept Drift
