Abstract:This paper deals with the issue of concept drift in supervised machine learning. We make use of graphical models to elicit the visible structure of the data and we infer from there changes in the hidden context. Differently from previous concept-drift-detection methods, this application does not depend on the supervised machine learning model in use for a specific target variable, but it tries to assess the concept drift as independent characteristic of the evolution of a data set. Specifically we investigate … Show more
