Performance improvement of models using dual functioning TFs. Each panel shows for six representative CRMs the observed output of the CRM (solid grey) compared to the normalized predicted shape using different TF roles in the Reinitz model. The grey dashed line shows the prediction for the best role assignment and individual training on the CRM. In dashed red is shown the performance when using the literature configuration and trained simultaneously on all 44 CRMs. The solid coloured lines show the prediction of HbDual KrDual and HbKrDual, respectively, trained simultaneously. The model with the best over-all performance is displayed from the five independent repeats.
