Computer-implemented method for classifying a data chunk

Abstract

According to an embodiment, a computer-implemented method (100) for classifying a data chunk comprises: obtaining (101) information about a plurality of classes; forming (102) a plurality of subsets of classes based on the plurality of classes, wherein each subset of classes in the plurality of subsets of classes comprises at least two classes from the plurality of classes; obtaining (103) a data chunk; performing (104) a plurality of subclassifications of the data chunk according to the plurality of subsets of classes using a generative artificial intelligence, GAI, model, wherein each subclassification in the plurality of subclassifications assigns the data chunk to a subresult class in a corresponding subset of classes of the plurality of subsets of classes, thus obtaining a plurality of subresult classes; and classifying (105) the data chunk to a result class in the plurality of subresult classes using the GAI model.
