Title: POST-PROCESSING OUTPUT DATA OF A CLASSIFIER
Abstract: The invention is directed to a computer-implemented method for post-processing output data of a classifier, comprising the steps:a. Providing a validation data set with a plurality of labelled sample pairs, wherein each labelled sample pair comprises a model input and a corresponding model output (S1) ;b. Providing a plurality of perturbation levels (S2);c. Generating at least one perturbated sample pair for each labelled sample pair of the plurality of labelled sample pairs using a perturbation method based on the respective labelled sample pair and at least one perturbation level of the plurality of perturbation levels (S3);d. Determining a post-processing model based on the plurality of perturbated sample pairs (S4);e. Applying the determined post-processing model on testing data to post-process the output data of the classifier (S5); andf. Providing the post-processed output data of the classifier (S6). Further, the invention relates to a corresponding technical unit and computer program product.
