Brunner L. and Sippel S. (2023): Identifying climate models based on their daily output using machine learning, Env. Data Sci., PDF, Supplement
Confusion matrix showing the frequency of predicted versus true labels. The main diagonal shows correct predictions using green shading, purple shading indicates misclassifications within a model family, and red shading indicates other misclassifications. Two cases are singled out: assignments within the HadGEM family and confusions between models and the two reanalyses ERA5 and MERRA2.
