    This paper describes the TALP–UPC system in the Spanish–English WMT 2016 biomedical shared task. Our system is a standard phrase-based system enhanced with vocabulary expansion using bilingual word embeddings and a ...
  • WMT 2016 Multimodal translation system description based on bidirectional recurrent neural networks with double-embeddings 

    Rodríguez Guasch, Sergio; Ruiz Costa-Jussà, Marta (0)
    Text en actes de congrés
    Accés obert
    Bidirectional Recurrent Neural Networks (BiRNNs) have shown outstanding results on sequence-to-sequence learning tasks. This architecture becomes specially interesting for multimodal machine translation task, since BiRNNs ...
  • Neural machine translation using bitmap fonts 

    Aldón Mínguez, David; Ruiz Costa-Jussà, Marta; Rodríguez Fonollosa, José Adrián (2016)
    Comunicació de congrés
    Accés obert
    Recently, translation systems based on neural networks are starting to compete with systems based on phrases. The systems which are based on neural networks use vectorial repre- sentations of words. However, one of the ...
  • High performance doa trackers derived from paralell low resolution detectors 

    Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (IEEE IEEE COMPUTER SOCIETY PRESS, 1996)
    Text en actes de congrés
    Accés obert
    Traditionally, high resolution spectral direction of arrival (DOA) estimation has been associated with algorithms rather than with a processing scheme or architecture. Motivated by previous work on feasible implementations ...
  • Partition coding using multi-grid chain code and motion compensation 

    Marqués Acosta, Fernando; Gasull Llampallas, Antoni (?, 1996)
    Text en actes de congrés
    Accés obert
    In this paper, a lossy partition coding technique is presented which leads to decoded partitions with unnoticeable losses. It uses a hexagonal grid for contour representation and it is based on the concept of multi-grid ...
  • Blind multiuser detection using hidden markov models theory 

    Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Rodríguez Fonollosa, Javier (BOB WERNER IEEE, 1996)
    Text en actes de congrés
    Accés obert
    We present an adaptive algorithm based on the theory of hidden Markov models (HMM) which is capable of jointly detecting the users in a DS-CDMA system. The proposed technique is near-far resistant and completely blind in ...
  • A segmentation-based coding system allowing manipulation of objects (sesame) 

    Marqués Acosta, Fernando; Salembier Clairon, Philippe Jean; Pardàs Feliu, Montse; Marcotegui Iturmendi, Beatriz (?, 1996)
    Text en actes de congrés
    Accés obert
    We present a coding scheme that achieves, for each image in the sequence, the best segmentation in terms of rate-distortion theory. It is obtained from a set of initial regions and a set of available coding techniques. The ...
  • A mobile controlled algorithm for improving the throughput in a s-aloha ds-cdma system 

    Sallent Roig, José Oriol; Agustí Comes, Ramon (Institute of Electrical and Electronics Engineers (IEEE), 1996)
    Text en actes de congrés
    Accés obert
    This paper presents a novel adaptive DS-CDMA slotted-ALOHA packet random access scheme with transmitter-based spreading codes for mobiles. It is aimed at improving the throughput and message delay delivery when traffic ...
  • Partition tree for a segmentation-based video coding system 

    Pardàs Feliu, Montse; Salembier Clairon, Philippe Jean; Marqués Acosta, Fernando; Morros, R (Institute of Electrical and Electronics Engineers (IEEE), 1996)
    Text en actes de congrés
    Accés obert
    In this paper we describe a very low bit rate video coding system that belongs to the class of object based coding systems. The system takes advantage of homogeneity in both gray level and motion, trying to use the most ...
  • Trapping of light beams and formation of spatial solitary waves in quadratic nonlinear media 

    Torner Sabata, Lluís; Torruellas, W; Stegeman, G; Menyuk, C; Wright, E (Institute of Electrical and Electronics Engineers (IEEE), 1996)
    Text en actes de congrés
    Accés obert
    Summary form only given. In this paper we report the outcome of our comprehensive investigations to study the dynamics of the beam trapping in both bulk crystals and optical planar waveguides made of quadratic nonlinear ...
