  • CBR and MBR techniques: review for an application in the emergencies domain 

    Merida-Campos, Carlos; Rollón Rico, Emma (2003-06-01)
    External research report
    Open Access
    The purpose of this document is to provide an in-depth analysis of current reasoning engine practice and the integration strategies of Case Based Reasoning and Model Based Reasoning that will be used in the design and ...
  • Database design and administration 

    Abelló Gamazo, Alberto; Rodríguez González, María Elena; Rollón Rico, Emma (Edicions UPC, 2010)
    Restricted access to the UPC academic community
    It is assumed that the reader has previous knowledge on a conceptual modeling language as well as on relational databases.<br>This book is thought as a tool to make easy to follow a specific course on database design and ...
  • Decomposing utility functions in Bounded Max-Sum for distributed constraint optimization 

    Rollón Rico, Emma; Larrosa Bondia, Francisco Javier (Springer, 2014)
    Conference report
    Open Access
    Bounded Max-Sum is a message-passing algorithm for solving distributed Constraint Optimization Problems (DCOP) able to compute solutions with a guaranteed approximation ratio. In this paper we show that the introduction ...
  • Diseño y administración de bases de datos 

    Abelló Gamazo, Alberto; Rodríguez González, María Elena; Rollón Rico, Emma (Edicions UPC, 2006)

    Se asume que el lector ya tiene conocimientos previos de un lenguaje de modelado conceptual y de bases de datos relacionales. En este libro se aborda la problemática y la multiplicidad que supone obtener un esquema relacional ...
  • Introducció de tècniques d’aprenentatge col•laboratiu i semi-presencial en l’àmbit de bases de dades 

    Abelló Gamazo, Alberto; Urpí Tubella, Antoni; Rollón Rico, Emma; Rodríguez, M. Elena; Casany Guerrero, María José; Quer, Carme; Burgués Illa, Xavier; Martí, Carme (Universitat Politècnica de Catalunya. Institut de Ciències de l'Educació, 2008-02-07)

    Podem classificar les àrees d’actuació del projecte en tres grups diferents: 1) S'han reestructurat els temaris de les assignatures de tota la branca de “bases de dades” de la FIB. 2) S’han introduït activitats participatives ...
  • Limited discrepancy AND/OR search and its application to optimization tasks in graphical models 

    Larrosa Bondia, Francisco Javier; Rollón Rico, Emma; Dechter, Rina (AAAI Press (Association for the Advancement of Artificial Intelligence), 2016)
    Conference report
    Open Access
    Many combinatorial problems are solved with a Depth-First search (DFS) guided by a heuristic and it is well-known that this method is very fragile with respect to heuristic mistakes. One standard way to make DFS more robust ...
  • Multi-objective optimization in graphical models 

    Rollón Rico, Emma (Universitat Politècnica de Catalunya, 2008-11-03)
    Doctoral thesis
    Open Access
    Many real-life optimization problems are combinatorial, i.e. they concern a choice of the best solution from a finite but exponentially large set of alternatives. Besides, the solution quality of many of these problems ...
  • New mini-bucket partitioning heuristics for bounding the probability of evidence 

    Rollón Rico, Emma; Dechter, Rina (2009)
    Conference report
    Open Access
    Mini-Bucket Elimination (MBE) is a well-known approximation algorithm deriving lower and upper bounds on quantities of interest over graphical models. It relies on a procedure that partitions a set of functions, called ...
  • Semiring-based mini-bucket partitioning schemes 

    Rollón Rico, Emma; Larrosa Bondia, Francisco Javier; Dechter, Rina (AAAI Press. Association for the Advancement of Artificial Intelligence, 2013)
    Conference report
    Restricted access - publisher's policy
    Graphical models are one of the most prominent frameworks to model complex systems and efficiently query them. Their underlying algebraic properties are captured by a valuation structure that, most usually, is a semiring. ...
