This paper presents an alternative identification approach for the Markov m
odel studied in [3]. Our approach estimates the state sequence and model pa
rameters with the help of a clustering analysis by the rival penalized comp
etitive learning (RPCL) algorithm [4]. Compared to the method in [3], this
new approach not only extends the model from scalar states to multi-dimensi
onal ones, but also makes the model identification with the correct number
of states decided automatically. The experiments have shown that it works w
ell.
