Hidden-Variable Models for Discriminative Reranking.
Hidden–Variable Models for Discriminative Reranking Terry Koo MIT CSAIL firstname.lastname@example.org Michael Collins MIT CSAIL email@example.com Abstract We describe a new method for the representation of NLP structures within reranking approaches. We make use of a conditional log–linear model, with hidden variables representing the assignment of lexical items to word clusters or word senses. The model learns to automatically make these assignments based on a discriminative training criterion. Trainin
