Abstract

Hidden Markov models are traditionally decoded by the Viterbi
algorithm which finds the highest probability state path in the
model. In recent years, several limitations of the Viterbi decoding
have been demonstrated, and new algorithms have been developed to
address them (Kall et al., 2005; Brejova et al., 2007; Gross et al.,
2007; Brown and Truszkowski, 2010). In this paper, we propose a new
efficient highest expected reward decoding algorithm (HERD) that
allows for uncertainty in boundaries of individual sequence
features. We demonstrate usefulness of our approach on jumping HMMs
for recombination detection in viral genomes.
