TL;DR

This work proposes TagProp, a discriminatively trained nearest neighbor model that allows the integration of metric learning by directly maximizing the log-likelihood of the tag predictions in the training set, and introduces a word specific sigmoidal modulation of the weighted neighbor tag predictions to boost the recall of rare words.
