WebInfrastructure Deterioration Prediction with a Poisson Hidden Markov Model on Time Series Data Nam Lethanh, Ph.D.1; Kiyoyuki Kaito, Ph.D.2; and Kiyoshi Kobayashi, Ph.D.3 Abstract: The deterioration of a pavement surface can be described in terms of the presence andseverityof distinct distresses,like potholes, cracking, and rutting. Web18 de ago. de 2010 · The theory of hidden Markov models is already well-developed [13]. On the other hand, very little research has been done into the extended model with multiple observation processes. The mainly algorithmic solutions in the theory of hidden Markov models with a single observation process cannot be
