Estimate exponential memory decay in Hidden Markov Model and its applications

17 Oct 2017 Felix X. -F. Ye Yi-An Ma Hong Qian

Inference in hidden Markov model has been challenging in terms of scalability due to dependencies in the observation data. In this paper, we utilize the inherent memory decay in hidden Markov models, such that the forward and backward probabilities can be carried out with subsequences, enabling efficient inference over long sequences of observations...
