... Bayesian approach allows us to automatically select values for the hyperparameters by treating them as addi- tional variables in the model. We augment the model with priors over the hyperparameters ... we achieve average tagging accuracy of 86.8%. This far surpasses the MLHMM performance of 74.5%, and is closer to the 90.1% accuracy of CRF/CE on the same data set u...
