International audienceWhile switching Markov state-space models arise in many applied science applications like signal processing, bioinformatics, etc., it is often difficult to establish their identifiability which is essential for parameters estimation. This paper discusses the simple case in which the unknown continuous state and the observations are scalars. We demonstrate that if a prior information relating the observations to the unknown continuous state at a time t0 is available, and if the Markov chain is irreducible and aperiodic, the set of the model parameters will be " globally structurally identifiable ". In addition, we show that under these constraints, the model parameters can be efficiently estimated by an EM algorithm.Les...
