Terminology of Combining the Sentences of Farsi Language with the Viterbi Algorithm and BI-GRAM Labeling
This paper, based on the Viterbi algorithm, selects the most likely combination of different wording from a variety of scenarios. In this regard, the Bi-gram and Unigram tags of each word, based on the letters forming the words, as well as the bigram and unigram labels After the breakdown into the composition or moment of transition from the decomposition to the combination obtained from th...
متن کاملGeneralized Baum-Welch and Viterbi Algorithms Based on the Direct Dependency among Observations
The parameters of a Hidden Markov Model (HMM) are transition and emission probabilities‎. ‎Both can be estimated using the Baum-Welch algorithm‎. ‎The process of discovering the sequence of hidden states‎, ‎given the sequence of observations‎, ‎is performed by the Viterbi algorithm‎. ‎In both Baum-Welch and Viterbi algorithms‎, ‎it is assumed that...
متن کاملUsing robust viterbi algorithm and HMM-modeling in unit selection TTS to replace units of poor quality
In hidden Markov model-based unit selection synthesis, the benefits of both unit selection and statistical parametric speech synthesis are combined. However, conventional Viterbi algorithm is forced to do a selection also when no suitable units are available. This can drift the search and decrease the overall quality. Consequently, we propose to use robust Viterbi algorithm that can simultaneou...
متن کاملEfficient Staggered Decoding for Sequence Labeling
The Viterbi algorithm is the conventional decoding algorithm most widely adopted for sequence labeling. Viterbi decoding is, however, prohibitively slow when the label set is large, because its time complexity is quadratic in the number of labels. This paper proposes an exact decoding algorithm that overcomes this problem. A novel property of our algorithm is that it efficiently reduces the lab...
متن کاملA Baseband Signal Processing Scheme for Joint Data Frame Synchronization and Symbol Decoding for RFID Systems
We proposed a novel Viterbi-based algorithm using jiggling substates for joint data sequence detection, symbol boundary selfcalibration, and signal frame synchronization for the EPC-Global Gen-2 system. The proposed algorithm first represents the dataencoded scheme as a trellis diagram, and then, as a consequence; the data sequence estimation can be carried out through the Viterbi algorithm. Mo...
