Notes. Predicted labels are obtained from the class with the maximum posterior probability. The labels ‘original’ and ‘cleaned’ refer to the results evaluated on the full validation data set and the cleaned validation data set, respectively. Combmod-α is the parametric combination of the GDR3 DSC Allosmod and Specmod, where αglob = [1.0,0.6,0.5] and αvari = [0.6, 0.6, 0.5]. Results of the extragalactic classes are highlighted in boldface.
