Parametric modeling of PDF using a convolution of one-sided exponentials: application to HMM
(European Association for Signal Processing (EURASIP), 1994)
Text en actes de congrés
Accés obert -
Performance evaluation of interference cancellation techniques using adaptive antennas
(IEEE Vehicular Technology Society, 1998)
Text en actes de congrés
Accés obertTwo array-based algorithms, which jointly exploit or compensate for the spatial and temporal characteristics of the propagation channel, are proposed for intercell interference suppression in UMTS scenarios. The first one ... -
Pitch analysis of noisy speech
(Elsevier, 1992)
Text en actes de congrés
Accés obert -
Pitch determination of noisy speech using higher order statistics
(. IEEE, 1992)
Text en actes de congrés
Accés obertThe use of third-order statistics to determine the pitch of a speech signal and how they can eliminate the effect of a wide range of noises, including those generated by periodic sources, are shown. The proposed algorithm ... -
Predictive SVD-transform coding of speech with adaptive vector quantization
(1991)
Text en actes de congrés
Accés obertA predictive transform coder using singular value decomposition (SVD) and adaptive vector quantization (AVQ) is presented. The linear predictive coding (LPC) excitation is obtained by a weighting VQ quantization of the SVD ... -
Probabilistic algorithms for blind adaptive multiuser detection
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-11-30)
Article
Accés obertIn this paper, two probabilistic adaptive algorithms for jointly detecting active users in a DS-CDMA system are reported. The first one, which is based on the theory of hidden Markov models (HMM’s) and the Baum–Wech ... -
Rational characteristic functions and markov chains
(. S.N., 1995)
Text en actes de congrés
Accés obertAbstract 1 We investigate in this paper how to estimate the density function of a random variable using a parametric ARMA model for its characteristic function. The choice of this model is motivated by the fact that this ... -
Robust LPC vector quantization based on kohonen's design algorithm
(Elsevier, 1990)
Text en actes de congrés
Accés obert -
Sample cumulants of stationary processes: asymptotic results
(1995-04)
Article
Accés obertIn this paper, we present the formulas of the covariances of the second-, third-, and fourth-order sample cumulants of stationary processes. These expressions are then used to obtain the analytic performance of FIR system ... -
Search engine for multilingual audiovisual contents
(2012)
Comunicació de congrés
Accés obertThis paper describes the BUCEADOR search engine, a web server that allows retrieving. multimedia documents (text, audio, video) in different languages. All the documents are translated into the user language and are ... -
Simplied gradient calculation in iir lattice adaptive filters
(1991-07)
Article
Accés obertA simplified algorithm is presented for computing the gradient in adaptive IIR (infinite impulse response) lattice filters. For a filter with N zeros and N poles, this algorithm requires only order N computations. Several ... -
Spectral sensitivity and convergence rate in adaptive IIR filtering
(IEEE IEEE PRESS, 1990)
Text en actes de congrés
Accés obert -
State-of-the-Art word reordering approaches in statistical machine translation: a survey
(2009-11-01)
Article
Accés obertThis paper surveys several state-of-the-art reordering techniques employed in Statistical Machine Translation systems. Reordering is understood as the word-order redistribution of the translated words. In original SMT ... -
Subband splitting, adaptive scalar prediction and vector quantization for speech coding
(1988)
Text en actes de congrés
Accés obertThis paper describes a new coding structure based on the combination of Vector Quantizati.on, Linear Prediction l)nd Subband Splitting that achieves high guality speech at rates below 10 Kbit/sec. In this scheme, a vector ... -
Syntax-based reordering for statistical machine translation
(Elsevier, 2011-10)
Article
Accés restringit per política de l'editorialIn this paper, we develop an approach called syntax-based reordering (SBR) to handling the fundamental problem of word ordering for statistical machine translation (SMT). We propose to alleviate the word order challenge ... -
Syntax-driven iterative expansion language models for controllable text generation
(Association for Computational Linguistics, 2020)
Comunicació de congrés
Accés obertThe dominant language modeling paradigm handles text as a sequence of discrete tokens. While that approach can capture the latent structure of the text, it is inherently constrained to sequential dynamics for text generation. ... -
System identification using a linear combination of cumulant slices
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1993-07-01)
Article
Accés obertIn this paper we develop a new linear approach to identify the parameters of a moving average (MA) model from the statistics of the output. First, we show that, under some constraints, the impulse response of the system ... -
Terminal digital para la transmisión de voz y datos sobre banda fónica
(Consejo Superior de Investigaciones Científicas (CSIC), 1986)
Text en actes de congrés
Accés obertThe development of a terminal for voice and data transmision based on the TMS 32010 one-chip microprocessor is described. Simple solutions are provided for the digital implementations of the filters, compandor, equalizer ... -
Terminology-aware segmentation and domain feature for the WMT19 biomedical translation task
(Association for Computational Linguistics, 2019)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work, we give a description of the TALP-UPC systems submitted for the WMT19 Biomedical Translation Task. Our proposed strategy is NMT model-independent and relies only on one ingredient, a biomedical terminology ... -
