  • Boosted Random ferns for object detection 

    Villamizar Vergel, Michael Alejandro; Andrade-Cetto, Juan; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2018-02-01)
    Article
    Accés obert
    In this paper we introduce the Boosted Random Ferns (BRFs) to rapidly build discriminative classifiers for learning and detecting object categories. At the core of our approach we use standard random ferns, but we introduce ...
  • TED: a tolerant edit distance for segmentation evaluation 

    Funke, Jan; Klein, J.; Moreno-Noguer, Francesc; Cardona, A.; Cook, Matthew (2017-02-15)
    Article
    Accés obert
    In this paper, we present a novel error measure to compare a computer-generated segmentation of images or volumes against ground truth. This measure, which we call Tolerant Edit Distance (TED), is motivated by two observations ...
  • A cognitive architecture for automatic gardening 

    Agostini, Alejandro Gabriel; Alenyà Ribas, Guillem; Fischbach, Andreas; Scharr, Hanno; Woergoetter, Florentin; Torras, Carme (2017-06-01)
    Article
    Accés obert
    In large industrial greenhouses, plants are usually treated following well established protocols for watering, nutrients, and shading/light. While this is practical for the automation of the process, it does not tap the ...
  • Relational reinforcement learning for planning with exogenous effects 

    Martinez Martinez, David; Alenyà Ribas, Guillem; Ribeiro, Tony; Inoue, Katsumi; Torras, Carme (2017)
    Article
    Accés obert
    Probabilistic planners have improved recently to the point that they can solve difficult tasks with complex and expressive models. In contrast, learners cannot tackle yet the expressive models that planners do, which forces ...
  • Relational reinforcement learning with guided demonstrations 

    Martínez Martínez, David; Alenyà Ribas, Guillem; Torras, Carme (2017)
    Article
    Accés obert
    Model-based reinforcement learning is a powerful paradigm for learning tasks in robotics. However, in-depth exploration is usually required and the actions have to be known in advance. Thus, we propose a novel algorithm ...
  • Visual grasp point localization, classification and state recognition in robotic manipulation of cloth: an overview 

    Jimenez Schlegl, Pablo (2017)
    Article
    Accés obert
    Cloth manipulation by robots is gaining popularity among researchers because of its relevance, mainly (but not only) in domestic and assistive robotics. The required science and technologies begin to be ripe for the ...
  • Random clustering ferns for multimodal object recognition 

    Villamizar Vergel, Michael Alejandro; Garrell Zulueta, Anais; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2017-09-01)
    Article
    Accés obert
    We propose an efficient and robust method for the recognition of objects exhibiting multiple intra-class modes, where each one is associated with a particular object appearance. The proposed method, called random clustering ...
  • 3D human pose tracking priors using geodesic mixture models 

    Simo Serra, Edgar; Torras, Carme; Moreno-Noguer, Francesc (2017-04-01)
    Article
    Accés obert
    We present a novel approach for learning a finite mixture model on a Riemannian manifold in which Euclidean metrics are not applicable and one needs to resort to geodesic distances consistent with the manifold geometry. ...
  • Dual REPS: a generalization of relative entropy policy search exploiting bad experiences 

    Colomé Figueras, Adrià; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2017-08-01)
    Article
    Accés obert
    Policy search (PS) algorithms are widely used for their simplicity and effectiveness in finding solutions for robotic problems. However, most current PS algorithms derive policies by statistically fitting the data from the ...
  • Teaching robot’s proactive behavior using human assistance 

    Garrell Zulueta, Anais; Villamizar Vergel, Michael Alejandro; Moreno-Noguer, Francesc; Sanfeliu Cortés, Alberto (2017)
    Article
    Accés obert
    In recent years, there has been a growing interest in enabling autonomous social robots to interact with people. However, many questions remain unresolved regarding the social capabilities robots should have in order to ...
  • Assistent(e)s robòtiqu(e)s: un punt de confluència entre tecnociència i humanitats 

    Torras, Carme (2017)
    Article
    Accés obert
    La robòtica industrial està donant pas a una robòtica de caire més social i assistencial. Simplificant, podríem dir que mentre els robots industrials han ocupat llocs de treball que requereixen manipular materials rígids ...
  • 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 ...
