  • A machine learning pipeline for supporting differentiation of glioblastomas from single brain metastases 

    Mocioiu, Victor; de Barros, Nuno M. Pedrosa; Ortega Martorell, Sandra; Slotboom, Johannes; Knecht, Urspeter; Arús, Carles; Vellido Alcacena, Alfredo; Julià Sapé, Margarida (I6doc.com, 2016)

    Accés obert
    Machine learning has provided, over the last decades, tools for knowledge extraction in complex medical domains. Most of these tools, though, are ad hoc solutions and lack the systematic approach that would be required to ...
  • Instance and feature weighted k-nearest-neighbors algorithm 

    Prat, Gabriel; Belanche Muñoz, Luis Antonio (I6doc.com, 2016)
    Text en actes de congrés
    Accés obert
    We present a novel method that aims at providing a more stable selection of feature subsets when variations in the training process occur. This is accomplished by using an instance-weighting process -assigning different ...
  • Physics and machine learning: Emerging paradigms 

    Martín Guerrero, José; Lisboa, Paulo J G; Vellido Alcacena, Alfredo (I6doc.com, 2016)
    Text en actes de congrés
    Accés obert
    Current research in Machine Learning (ML) combines the study of variations on well-established methods with cutting-edge breakthroughs based on completely new approaches. Among the latter, emerging paradigms from Physics ...
  • Look-ahead with mini-bucket heuristics for MPE 

    Dechter, Rina; Kask, Kalev; Lam, William; Larrosa Bondia, Francisco Javier (AAAI Press (Association for the Advancement of Artificial Intelligence), 2016)
    Comunicació de congrés
    Accés obert
    The paper investigates the potential of look-ahead in the con-text of AND/OR search in graphical models using the Mini-Bucket heuristic for combinatorial optimization tasks (e.g., MAP/MPE or weighted CSPs). We present and ...
  • Limited discrepancy AND/OR search and its application to optimization tasks in graphical models 

    Larrosa Bondia, Francisco Javier; Rollón Rico, Emma; Dechter, Rina (AAAI Press (Association for the Advancement of Artificial Intelligence), 2016)
    Text en actes de congrés
    Accés obert
    Many combinatorial problems are solved with a Depth-First search (DFS) guided by a heuristic and it is well-known that this method is very fragile with respect to heuristic mistakes. One standard way to make DFS more robust ...
  • A methodology for maintaining consistency between conceptual interpretations of nested partitions 

    Sevilla-Villanueva, Beatriz; Gibert, Karina; Sànchez-Marrè, Miquel (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The relationship between interpretations of nested partitions is analyzed in this work, since there are multiple situations where a refinement of the original partition arises. As a result, a new methodology NCI-IMS is ...
  • A Framework for animation in global illumination environments 

    Martín Campos, Ignacio Clemente; Pueyo, X; Tost Pardell, Daniela (1998-06)
    Text en actes de congrés
    Accés obert
    This paper proposes a framework for the production of animations of high quality radiosity environments which makes use of the a-priori knowledge of the dynamic properties of the scene in order to exploit temporal ...
  • Detecting which teaching competences should be reinforced in an engineering lecturer training program 

    López Álvarez, David; Pérez Poch, Antoni (European Society for Engineering Education (SEFI), 2016)
    Text en actes de congrés
    Accés obert
    In Catalonia (Spain), each university is required by law to offer lecturers a learning framework. This requirement is met by specialized centers: at our technical university, Universitat Politècnica de Catalunya (UPC) this ...
  • Ring oscillator clocks and margins 

    Cortadella Fortuny, Jordi; Lupon Navazo, Marc; Moreno Vega, Alberto; Roca Pérez, Antoni; Sapatnekar, Sachin (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés obert
    How much margin do we have to add to the delay lines of a bundled-data circuit? This paper is an attempt to give a methodical answer to this question, taking into account all sources of variability and the existing EDA ...
  • Kauffman's adjacent possible in word order evolution 

    Ferrer Cancho, Ramon (2016)
    Text en actes de congrés
    Accés obert
    Word order evolution has been hypothesized to be constrained by a word order permutation ring: transitions involving orders that are closer in the permutation ring are more likely. The hypothesis can be seen as a particular ...
