    • An Evaluation of the Usefulness of Case-Based Explanation 

      Cunningham, Padraig; Doyle, Donal; Loughrey, John (Trinity College Dublin, Department of Computer Science, 2003)
      One of the perceived benefits of Case-Based Reasoning (CBR) is the potential to use retrieved cases to explain predictions. Surprisingly, this aspect of CBR has not been much researched. There has been some early work on ...

    • Case-Based Plan Recognition in Computer Games 

      Fagan, Michael; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2003)
      In this paper we explore the use of case-based plan recognition to predict a player?s actions in a computer game. The game we work with is the classic Space Invaders game and we show that case-based plan recognition ...

    • Discovering genome expression patterns with self-organizing neural networks 

      Azuaje, Francisco (Trinity College Dublin, Department of Computer Science, 2002)
      Self-organizing neural networks represent a family of useful clusteringbased classification methods in several application domains. One such technique is the Kohonen Self-Organizing Feature Map ...

    • Simulation Frameworks for the Teaching and Learning of Distributed Algorithms 

      O'Donnell, Fionnuala (University of Dublin, Trinity College. Department of Computer Science, 2006-02)
      Teaching and learning about distributed algorithms is difficult. This is because distributed algorithms are made up of multiple independent elements, each with their own state and control, who interact through the exchange ...

    • SOAP in a mobile Environment 

      Dolan, Liam (Trinity College Dublin. Department of Computer Science, 2004-09)
      Recent years has seen a dramatic rise in the number of mobile devices in use. These devices include PDAs, mobile phones and embedded devices such as those found in cars for satellite tracking. As the use of these devices ...

    • Automated Web Service Composition 

      Murtagh, Donal (Trinity College Dublin. Department of Computer Science, 2004-09)
      Web content has traditionally been dominated by documents intended for human interpretation. However, the recent advent of Web Services has played a key role in evolving the Web from a mere document repository to a provider ...

    • SourceWeave.Net: Cross Language Source Code Weaving 

      Jackson, Andrew (Trinity College Dublin. Department of Computer Science, 2003-09)
      A well modularised software system reduces complexity and supports change. Separating concerns as a means of achieving good modularisation, is therefore one of the primary principles in software engineering. In general, ...
