Measurement of the sensitivity of classifiers based on interacting faults

A non-transitory machine-readable data carrier on which is stored a computer program for measuring sensitivity of a classifier, the classifier being configured to assign image data to one or multiple classes of a predefined classification, to changes of the image data, the computer program, when executed by a computer, causing the computer to perform the following steps:

• providing at least one input data set including image data;
• ascertaining, using the classifier, an initial class assignment for the at least one input data set;
• ascertaining, from the input data set, a predefined number of different faults based on objectives, in that:
• a modification of the input data set formed by a joint application of all of the faults is mapped by the classifier to a class assignment, which differs from the initial class assignment according to a stipulation of a predefined criterion;
• and
• a modification of the input data set formed by applying only one of the faults is mapped by the classifier to a class assignment, which corresponds to the initial class assignment according to the stipulation of the predefined criterion.
