Abstract
A new principle for performing polychotomous classification with pairwise classifiers is introduced: if pairwise classifier \( \mathcal{N}_{ij} \), trained to discriminate between classes i and j, responds āiā for an input x from an unknown class (not necessarily i or j), one can at best conclude that x ā j. Thus, the output of pairwise classifier \( \mathcal{N}_{ij} \) can be interpreted as a vote against the losing class j, and not, as existing methods propose, as a vote for the winning class i. Both a discrete and a continuous classification model derived from this principle are introduced.
