To meet the increasing complexity of mobile multimedia applications, the System on Chip (SoC) equipping modern mobile devices integrate powerful heterogeneous processing elements among which General Purpose Processors (GPP), Digital Signal Processors (DSP), hardware accelerator are the most common ones. Due to the ever-growing gap between battery lifetime and hardware/software complexity in add...

This paper introduces a new open source, WFST-based toolkit for Grapheme-toPhoneme conversion. The toolkit is efficient, accurate and currently supports a range of features including EM sequence alignment and several decoding techniques novel in the context of G2P. Experimental results show that a combination RNNLM system outperforms all previous reported results on several standard G2P test se...

New efficient algorithm for maximum likelihood soft-decision decoding of the Leech lattice is presented. The superiority of this decoder with respect to both computational and memory complexities, compared to previously published decoding methods is demonstrated. Gain factors in the range of 2-10 are achieved. The Leech lattice has been recently suggested for practical implementation of block-c...

Aiming at bridging the gap between the maximum likelihood decoding (MLD) and the suboptimal iterative decodings for short or medium length LDPC codes, we present a generalized ordered statistic decoding (OSD) in the form of syndrome decoding, to cascade with the belief propagation (BP) or enhanced min-sum decoding. The OSD is invoked only when the decoding failures are obtained for the preceded...

Minimum risk estimation and decoding strategies based on lattice segmentation techniques can be used to refine large vocabulary continuous speech recognition systems through the estimation of the parameters of the underlying hidden Mark models and through the identification of smaller recognition tasks which provides the opportunity to incorporate novel modeling and decoding procedures in LVCSR...

The present study aims to explore whether an impairment in emotional facial expressions (EFE) decoding is specific to alcoholism compared with opiate dependence. An EFE decoding test consisting of 16 photographs of EFE portraying happiness, anger, sadness and disgust was administered to five different groups of 30 subjects each: recently detoxified alcoholics (RA); opiate addicts under methadon...

Hierarchical phrase-based translation (Hiero for short) models statistical machine translation (SMT) using a lexicalized synchronous context-free grammar (SCFG) extracted from word aligned bitexts. The standard decoding algorithm for Hiero uses a CKY-style dynamic programming algorithm with time complexity O(n3) for source input with n words. Scoring target language strings using a language mod...

This paper gives a new approach to decoding Hermite codes using the key equation, avoiding the use of majority voting. Our approach corrects up to (dmin − 1)/2 errors, and works up to some extent also beyond. We present an efficient implementation of our algorithm based on a Sugiyamatype iterative procedure for computing solutions of a key equation.
