Unlike traditional prediction methods, the presented approach does not require structural knowledge of the compounds in the considered mixtures. It is shown that this new approach outperforms the state-of-the-art prediction method for this property.enProperty modellingActivity coefficientsMatrix completionPrediction methodBinary mixturesDDC::500 Naturwissenschaften und Mathematik::540 Chemie::541 Physikalische ChemieDDC::500 Naturwissenschaften und Mathematik::510 Mathematik::519 Wahrscheinlichkeiten, angewandte Mathematikdoctoral thesis
