... Joint Training of Token Roles
In our previous system, filtering is conducted by
training a separate SVM classifier for each of the
eight token-roles described in Section 1. Each clas-
sifier uses a training ... The
identity of the responsible classifier is modeled as
a latent variable, which is filled in during training
using a latent SVM (LSVM) formulation. Our use
of an LSVM to a...
