    This brief paper addresses the problem of visually assessing the natural discriminability of the different subtypes that characterize class C G-Protein-Coupled Receptors, which are membrane proteins of interest in pharmacology, ...
  • Assessment of electrocardiograms with pretraining and shallow networks 

    Ribas Ripoll, Vicent; Wojdel, Anna; Ramos, Pablo; Romero Merino, Enrique; Brugada Terradellas, Josep (Computing in Cardiology, 2014)
    Conference report
    Open Access
    Objective: Clinical Decision Support Systems normally resort to annotated signals for the automatic assessment of ECG signals. In this paper we put forward a new method for the assessment of normal/abnormal heart function ...
  • Stopping criteria in contrastive divergence: Alternatives to the reconstruction error 

    Buchaca, David; Romero Merino, Enrique; Mazzanti Castrillejo, Fernando Pablo; Delgado Pin, Jordi (2014)
    Conference report
    Open Access
    Restricted Boltzmann Machines (RBMs) are general unsupervised learning devices to ascertain generative models of data distributions. RBMs are often trained using the Contrastive Divergence learning algorithm (CD), an ...
  • Developing professional skills at tertiary level: A model to integrate competencies across the curriculum

    The development of systems that allow multimodal interpretation of human-machine interaction is crucial to advance our understanding and validation of theoretical models of user behavior. In particular, a system capable ...
  • A MAP approach for convex non-negative matrix factorization in the diagnosis of brain tumors 

    Vilamala Muñoz, Albert; Belanche Muñoz, Luis Antonio; Vellido Alcacena, Alfredo (2014)
    Conference report
    Restricted access - publisher's policy
    Convex non-negative matrix factorization is a blind signal separation technique that has previously demonstrated to be well-suited for the task of human brain tumor diagnosis from magnetic resonance spectroscopy data. This ...
  • Classifying malignant brain tumours from 1H-MRS data using Breadth Ensemble Learning 

    Vilamala Muñoz, Albert; Belanche Muñoz, Luis Antonio; Vellido Alcacena, Alfredo (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report
    Open Access
    In neuro oncology, the accurate diagnostic identification and characterization of tumours is paramount for determining their prognosis and the adequate course of treatment. This is usually a difficult problem per se, due ...
  • Analysis of methods for playing human robot hide-and-seek in a simple real world urban environment 

    Goldhoorn, Alex; Sanfeliu Cortés, Alberto; Alquézar Mancho, René (Springer, 2013)
    Conference report
    Open Access
    The hide-and-seek game has many interesting aspects for studying cognitive functions in robots and the interactions between mobile robots and humans. Some MOMDP (Mixed Observable Markovian Decision Processes) models and a ...
  • Learning in networks of similarity processing neurons 

    Belanche Muñoz, Luis Antonio (2013)
    Conference report
    Open Access
    Similarity functions are a very flexible container under which to express knowledge about a problem as well as to capture the meaningful relations in input space. In this paper we describe ongoing research using similarity ...
  • Kernel functions for categorical variables with application to problems in the life sciences 

    Belanche Muñoz, Luis Antonio; Villegas, Marco (2013)
    Conference report
    Open Access
    We introduce a family of positive definite kernels specifically designed for problems described by categorical information. The kernels are based on the comparison of the probability mass function of the variables and have ...
