Classification multi-labels graduée: Apprendre les relations entre les labels ou limiter la propagation d'erreur ?
Abstract
Graded multi-label classification is the task of associating to each data a set of
labels according to an ordinal scale of membership degrees. Therefore labels can have
both order and co-occurrence relations. On the one hand, ignoring label relations may
lead to inconsistent predictions, and on the other hand, considering those relations may
spread the prediction error of a label to all related labels.
Unlike state of art approaches which can learn only relations fitting a predefined
dependency structure, our proposed approach doesn't set any predefined structure. The
idea is to learn all possible relations, then resolve cyclic dependencies using appropriate
measures. Those measures allow managing the compromise between considering label
relations for a consistent prediction, and ignoring them to minimize the prediction error
propagation.
