1. A method for determining at least one process variable of a medium, including the following method steps:
recording a first value for the process variable by means of a first method for determining the process variable;
recording a second value for the process variable by means of a second method for determining the process variable;
selecting at least one of the recorded values for the process variable using a classifier, wherein the classifier selects the at least one of the recorded values for the process variable based on process parameters, medium parameters and/or environmental parameters;
outputting the selected value for the process variable;
determining a feature vector;
designing the classifier to select the selected value for the process variable based on the feature vector; and
further including using a first and a second classifier, wherein the first classifier performs a feature extraction and/or creates the feature vector, and wherein the second classifier selects the selected value for the process variable based on the feature vector.
