Feature Relevance Analysis to Explain Concept Drift -- A Case Study in Human Activity Recognition

no code implementations20 Jan 2023 Pekka Siirtola, Juha Röning

As a main result of this article, it is shown that feature relevance analysis cannot only be used to detect the concept drift but also to explain the reason for the drift when a limited number of typical reasons for the concept drift are predefined.
