    Article
    Accés restringit per política de l'editorial
    Support Vector Machine (SVM) learning from imbalanced datasets, as well as most learning machines, can show poor performance on the minority class because SVMs were designed to induce a model based on the overall error. ...
  • Guest editorial: sensorimotor contingencies for cognitive robotics 

    Alenyà Ribas, Guillem; Tellez Lara, Ricardo; O'Regan, Kevin; Angulo Bahón, Cecilio (Institute of Electrical and Electronics Engineers (IEEE), 2017-06-09)
    Article
    Accés obert
    The sensorimotor approach to cognition states, that the key to bring semantics to the world of a robot, requires making the robot learn the relation between the actions that the robot performs and the change it experiences ...
