Concept drift

Last revised by Candace Makeda Moore on 10 Mar 2020

Concept drift refers to a phenomenon in the practical application of AI in which some underlying statistics or characteristics of one or more variables changes after the deployment of a model such that a specific AI model's predictive accuracy changes. Concept drift is a problem that can be managed by periodically testing and updating the models or in some cases deploying models that take the possibility of concept drift into account.
