    © 2017 Elsevier B.V. A post-processing technique for Support Vector Machine (SVM) algorithms for binary classification problems is introduced in order to obtain adequate accuracy on a priority class (labelled as a positive ...
  • Improving SVM classification on imbalanced datasets by introducing a new bias 

    Núñez Castro, Haydemar; Gonzalez Abril, Luis; Angulo Bahón, Cecilio (2017-10-14)
    Article
    Restricted access - publisher's policy
    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
    Open Access
    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 ...

    Assigning papers to reviewers is a large, long and difficult task for conference chairs and scientific committees. The paper reviewer assignment problem is a multi-agent problem which requires understanding reviewer expertise ...
  • Obstacle avoidance based-visual navigation for micro aerial vehicles 

    Aguilar Castillo, Wilbert Geovanny; Casaliglla, Veronica P.; Polit, Jose L. (2017-03-01)
    Article
    Open Access
    This paper describes an obstacle avoidance system for low-cost Unmanned Aerial Vehicles (UAVs) using vision as the principal source of information through the monocular onboard camera. For detecting obstacles, the proposed ...
  • 3D environment mapping using the Kinect V2 and path planning based on RRT algorithms
