Fig. 1From: New graphical models for sequential data and the improved state estimations by data-conditioned driving noisesA diagrammatic representation of the hidden Markov model, for which the underlying process \(x_n\) forms a Markov chain and emits a discrete time series of observation \(y_n\). The dashed arrows are used to emphasize that, in the graph model associated with the classical algorithms, the independent system noises \(w_n\) influencing \(x_n\) are not shownBack to article page
