A Nonparametric Bayesian Approach to Acoustic Model Discovery
A Nonparametric Bayesian Approach Acoustic Model Discovery
2014/11/27
We investigate the problem of acoustic modeling in which prior language-specific knowledge and transcribed data are unavailable. We present an unsupervised model that simultaneously segments the speec...
An Efferent-Inspired Auditory Model Front-End for Speech Recognition
efferent auditory model feature extraction
2014/11/27
In this paper, we investigate a closed-loop auditory model and explore its potential as a feature representation for speech recognition. The closed-loop representation consists of an auditory-based, e...
A Markov Model of Machine Translation using Non-parametric Bayesian Inference
Markov Model Machine Translation Non-parametric Bayesian Inference
2014/3/20
Most modern machine translation systems use phrase pairs as translation units, allowing for accurate modelling of phraseinternal translation and reordering. However phrase-based approaches are much le...
A user-centric model of voting intention from Social Media
Vasileios Lampos Daniel Preot¸ iuc-Pietro Trevor Cohn
2014/3/20
Social Media contain a multitude of user opinions which can be used to predict realworld phenomena in many domains including politics, finance and health. Most existing methods treat these problems as...
A temporal model of text periodicities using Gaussian Processes
A temporal model of text periodicities Gaussian Processes
2014/3/20
Temporal variations of text are usually ignored in NLP applications. However, text use changes with time, which can affect many applications. In this paper we model periodic distributions of words ove...
Learning Bilingual Linguistic Reordering Model for Statistical Machine Translati
Learning Bilingual Linguistic Reordering Model Statistical Machine Translati
2013/4/22
In this paper, we propose a method for learning reordering model for BTG-based statistical machine translation (SMT). The model focuses on linguistic features from bilingual phrases. Our method involv...
A Syntax-Driven Bracketing Model for Phrase-Based Translation
A Syntax-Driven Bracketing Model Phrase-Based Translation
2013/4/22
in the formally syntaxbased MT, a hierarchical tree generated by synchronous CFG rules associates the source sentence with the target sentence. In this paper, we propose a source dependency model to e...
