      Markovian models with hidden state are widely-used formalisms for modeling sequential phenomena. Learnability of these models has been well studied when the sample is given in batch mode, and algorithms with PAC-like ...

      This paper proposes a hybrid algorithm, combining Biased-Randomized (BR) processes with an Iterated Local Search (ILS) meta-heuristic, to solve the Multi-Depot Vehicle Routing Problem (MDVRP). Our approach assumes a ...
    • Communication requirements for team automata 

      Carmona Vargas, Josep; Beek, Maurice ter; Hennicker, Rolf; Kleijn, Jetty (Springer, 2017)
      Conference report
      Open Access
      Compatibility of components is an important issue in the quest for systems of systems that guarantee successful communications, free from message loss and indefinite waiting for inputs. In this paper, we investigate ...

      Conference report
      Open Access
      We consider systems composed of reactive components that collaborate through synchronised execution of common actions. These multi-component systems are formally represented as team automata, a model that allows a wide ...

      Article
      Open Access
      This paper presents a condition-based monitoring methodology based on novelty detection applied to industrial machinery. The proposed approach includes both, the classical classification of multiple a priori known scenarios, ...
    • Improving learning automata-based routing in Wireless Sensor Networks 

      Ahvar, Ehsan; Yannuzzi, Marcelo; Serral Gracià, René; Marín Tordera, Eva; Masip Bruin, Xavier; Ahvar, Shohreh (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Conference report
      Open Access
      Recent research in the field of Wireless Sensor Networks (WSNs) has demonstrated the advantages of using learning automata theory to steer the routing decisions made by the sensors in the network. These advantages include ...
    • Introducing reluctance motors in electric machines and drives courses:a new approach 

      Andrada Gascón, Pedro; Torrent Burgués, Marcel; Martínez Garcia, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Restricted access - publisher's policy
      The teaching of electrical machines and drives requires a new approach to make them more attractive to students, to address and overcome the limitations of time and resources that are usual in electrical engineering programs. ...
    • Learning probability distributions generated by finite-state machines 

      Castro Rabal, Jorge; Gavaldà Mestre, Ricard (Springer, 2016)
      Part of book or chapter of book
      Open Access
      We review methods for inference of probability distributions generated by probabilistic automata and related models for sequence generation. We focus on methods that can be proved to learn in the inference in the limit ...
    • Maquetas didácticas para la enseñanza de Teoría de Máquinas y Mecanismos: análisis comparativo del diseño, la fabricación, el control y el coste 

      Ponsa Banús, David (Universitat Politècnica de Catalunya, 2020-11-16)
      Bachelor thesis
      Open Access
      El presente Trabajo Final de Grado tiene dos objetivos principales, el primero es analizar las características constructivas, funcionales y el coste de adquisición de maquetas comercializadas para la enseñanza de la materia ...
    • Motor adaptation as a greedy optimization of error and effort 

      Emken, Jeremy L.; Benítez Iglesias, Raúl; Sideris, Athanasios; Bobrow, James E.; Reinkensmeyer, David J. (The American Physiological Society, 2007-03-31)
      Article
      Restricted access - publisher's policy
      thought of as a process in which the nervous system learns to anticipate the environmental forces to eliminate kinematic error. Here we show that motor adaptation can more generally be modeled as a process in which the ...
    • Programació de peces en màquines en paral·lel a múltiples nivells amb temps de preparació 

      Miquel Marcó, David (Universitat Politècnica de Catalunya, 2013-05)

      Open Access
      El problema tractat en el present projecte és una variant del problema de programació del taller mecànic. En aquesta variant hi ha una disposició de les màquines en paral·lel. A més, no tots els tipus de peces es poden ...
    • Proof complexity meets algebra 

      Atserias, Albert; Ochremiak, Joanna (Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2017)
      Conference report
