We see that most of the differences between the methods appear as differences among rare words, with the contribution of more common words being negligible.
the contributions of this paper are threefold: in proposing a langauge model with excellent performance and the accompanying advantages of Bayesian probabilistic models, in proposing a novel and efficient inference scheme for the model, and in establishing the direct correspondence between interpolated Kneser-Ney and the Bayesian approach.
