    We present a three-level cognitive system in a learning by demonstration context. The system allows for learn- ing and transfer on the sensorimotor level as well as the planning level. The fundamentally different data ...
  • Multi–layer health–aware economic predictive control of a pasteurization pilot plant 

    Karimi Pour, Fatemeh; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos (2018)
    Article
    Accés obert
    This paper proposes two different health-aware economic predictive control strategies that aim at minimizing the damage of components in a pasteurization plant. The damage is assessed with a rainflow-counting algorithm ...
  • A scalable, efficient, and accurate solution to non-rigid structure from motion 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc (2018)
    Article
    Accés obert
    Most Non-Rigid Structure from Motion (NRSfM) solutions are based on factorization approaches that allow reconstructing objects parameterized by a sparse set of 3D points. These solutions, however, are low resolution and ...
  • Robot motion adaptation through user intervention and reinforcement learning 

    Jevtic, Aleksandar; Colomé Figueras, Adrià; Alenyà Ribas, Guillem; Torras, Carme (Elsevier, 2018-04-01)
    Article
    Accés obert
    Assistant robots are designed to perform specific tasks for the user, but their performance is rarely optimal, hence they are required to adapt to user preferences or new task requirements. In the previous work, the potential ...
  • Task-driven active sensing framework applied to leaf probing 

    Foix Salmerón, Sergi; Alenyà Ribas, Guillem; Torras, Carme (2018-04-01)
    Article
    Accés obert
    This article presents a new method for actively exploring a 3D workspace with the aim of localizing relevant regions for a given task. Our method encodes the exploration route in a multi-layer occupancy grid map. This map, ...
  • Graph SLAM sparsification with populated topologies using factor descent optimization 

    Vallvé Navarro, Joan; Solà Ortega, Joan; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Article
    Accés obert
    Current solutions to the simultaneous localization and mapping (SLAM) problem approach it as the optimization of a graph of geometric constraints. Scalability is achieved by reducing the size of the graph, usually in two ...
