In addition, the calculation cost for estimating parameters of embedded joint PMs (HMMs) is independent of the number of HMMs, J, that we used (Suzuki et al., 2007).
the cost for calculating the JESS-CM parameters, λ and Θ, is essentially the same as executing T iterations of the MML estimation for a single HMM using the EM algorithm plus T + 1 time optimizations of the MAP estimation for a conventional supervised CRF if it converged when t = T .
