      Bound on the probability of HMM misclassification 

      Keroglou, C.; Hadjicostis, Christoforos N. (2011)
      In this paper we consider the problem of classifying a sequence of observations among two known hidden Markov models (HMMs). We use a classifier that minimizes the probability of error (i.e., the probability of misclassification), ...
