  journal={Pattern Recognition},
In this paper we consider two related problems in hidden Markov models (HMMs). One, how the various parameters of an HMM actually contribute to predictions of state sequences and spatio-temporal pattern recognition. Two, how the HMM parameters (and associated HMM topology) can be updated to improve performance. These issues are examined in the context of four di3erent experimental settings from pure simulations to observed data. Results clearly demonstrate the bene4ts of applying some critical… CONTINUE READING
