Abstract
Unsupervised ... es-
timation (MLE) of the model parameters.
We show using part- of- speech tagging that
a fully Bayesian approach can greatly im-
prove performance. Rather than estimating
a single set of parameters, ... optimal set of
parameter values, we seek to directly maximize the
probability of the hidden variables given the ob-
served data, integrating over all possible parame-
ter values. Using part- of- speech...
