  • A methodology to develop answers to definitional questions 

    Kanaan Izquierdo, Samir (2005-06)
    External research report
    Open Access
    This report tries to give a general vision of the state of art of the task of definitional question answering, by describing the task, illustrating the current interest on it, pointing out its main evaluation methods and ...
  • An evaluation framework based on gold standard models for definition question answering 

    Kanaan Izquierdo, Samir; Turmo Borras, Jorge (2006-05)
    External research report
    Open Access
    This paper presents a weak supervised evaluation framework for definition question answering (DefQA) called Solon. It automatically evaluates a set of DefQA systems using existing human definitions as gold standard models. ...

    Recent studies in neuroscience suggest that sniffing, namely sampling odors actively, plays an important role in olfactory system, especially in certain scenarios such as novel odorant detection. While the computational ...
  • Synthetic benchmarks for machine olfaction: Classification, segmentation and sensor damage 

    Ziyatdinov, Andrey; Perera Lluna, Alexandre (Elsevier, 2015-06-30)
    Article
    Open Access
    The design of the signal and data processing algorithms requires a validation stage and some data relevant for a validation procedure. While the practice to share public data sets and make use of them is a recent and still ...

    Metabolomics GC-MS samples involve high complexity data that must be effectively resolved to produce chemically meaningful results. Multivariate curve resolution-alternating least squares (MCR-ALS) is the most frequently ...
  • Aberrant DNA methylation in non-small cell lung cancer-associated fibroblasts 

    Vizoso, Manuel; Puig, Marta; Carmona, Francisco Javier; Maqueda, María; Velásquez, Adriana; Gómez, Antonio; Labernadie, Anna; Lugo, Roberto; Gabasa, Marta; Rigat-Brugarolas, Luis G.; Trepat, Xavier; Ramírez, Josep; Moran, Sebastian; Vidal, Enrique; Reguart, Noemí; Perera Lluna, Alexandre; Esteller, Manel; Alcaraz, Jordi (2015-12-01)
