Zusammenfassung:	A computer-implemented method for classifying whether an input signal, which comprises image and/or audio data, is anomalous or not with respect to a second data distribution using an anomaly classifier. The method includes: providing the input signal to the anomaly classifier; in the anomaly classifier, providing the input signal to a reference detector and a second detector; obtaining a reference value from the reference detector based on the input signal, the reference value characterizing the likelihood of the input signal to belong to a reference data distribution; obtaining a second value from the second detector based on the input signal, the second value characterizing the likelihood of the input signal to belong to the second data distribution; and providing an output signal, which characterizes a classification of the input signal as anomalous or not based on a comparison of the reference value and the second value.
