  • Random subspacing for regression ensembles 

    Tsymbal, Alexey (Trinity College Dublin, Department of Computer Science, 2004)
    In this work we present a novel approach to ensemble learning for regression models, by combining the ensemble generation technique of random subspace method with the ensemble integration methods of Stacked Regression ...

  • Re-using Implicit Knowledge in Short-term Information Profiles for Context-sensitive Tasks 

    Hayes, Conor; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2005-02-22)
    Typically, case-based recommender systems recommend single items to the on-line customer. In this paper we introduce the idea of recommending a user-defined collection of items where the user has implicitly encoded ...

  • A Reaction Diffusion Model for Wireless Indoor Propagation 

    Clarke, Andrew (Trinity College Dublin. Department of Computer Science, 2002-09)
    The biological pattern formation system known as the reaction-diffusion mechanism is used as a base for a simulator which will predict the propagation of RF signals in an indoor environment. The reaction diffusion system ...

  • A Real Time Implementation of TBMAC using IEEE 802.11b 

    Gleeson, Mark (Trinity College Dublin. Department of Computer Science, 2004-09)
    Emergency services, and automated vehicle platoons are frequently used examples of the need for real-time ad hoc communication, which demand that communication be time bounded overall. The medium access control protocol ...

  • Real-Time Communication in IEEE 802.11 Mobile Ad hoc Networks A Feasibility Study 

    CAHILL, VINNY; WEBER, STEFAN; GLEESON, MARK (2006)
    Achieving predictable communication latency in an ad hoc IEEE 802.11 wireless local area network necessitates an approach that overcomes the impact of the underlying non-deterministic contention-based medium access ...

  • Real-Time Display of Dublin Traffic Information on the Web 

    Dineen, Mark (Trinity College Dublin. Department of Computer Science, 2000-09)
    Many large-scale and highly specialised distributed systems such as Urban Traffic Control (UTC) systems produce considerable quantities of data on a real-time basis. This data is then frequently locked in a proprietary ...

  • Real-time Intrusion Detection for Ad hoc Networks 

    Stamouli, Ioanna (Trinity College Dublin. Department of Computer Science, 2003-09)
    In the recent years, wireless technology has enjoyed a tremendous rise in popularity and usage opening new fields of applications in the domain of networking. One such field concerns mobile ad hoc networks (MANETs) where ...

  • Removing Epistemological Bias From Empirical Observation of Neural Networks 

    Waldron, Ronan (Trinity College Dublin, Department of Computer Science, 1994-05-25)
    This paper addresses the application of neural network research to a theory of autonomous systems. Neural networks, while enjoying considerable success in autonomous systems applications, have failed to provide a firm ...

  • Representing Cases for CBR in XML 

    Coyle, Lorcan; Hayes, Conor; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2002-11)
    Case Based Reasoning has found increasing application on the Internet as a shopping assistant for e-commerce stores. The strength of CBR in this area stems from its reuse of the knowledge base associated with a particular ...

  • Representing Similarity for CBR in XML 

    Coyle, Lorcan; Doyle, Donal; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2004-07-26)
    As Case-Based Reasoning has matured as a discipline; the need for a standard means of representing case-based knowledge has come to the fore. While proposals exist for representing the vocabulary and the case-base ...

  • Research Directions for AI in Computer Games 

    Fairclough, Chris; Fagan, Michael; Mac Namee, Brian; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2001-10)
    The computer games industry is now bigger than the film industry. Until recently, technology in games was driven by a desire to achieve real-time, photo-realistic graphics. To a large extent, this has now been achieved. ...

  • Retrieval Issues in Real-World CBR Applications How far can we go with discrimination-nets? 

    Cunningham, Padraig; Smyth, Barry; Finn, Donal; Cahill, Eamonn (Trinity College Dublin, Department of Computer Science, 1993-06)
    We propose that analogical reasoning and case based reasoning (CBR) tasks can be usefully characterised as a continuum reflecting the remoteness of the remindings involved. Remindings in CBR are generally between semantically ...

  • Retrieval Issues in Real-World CBR Applications How far can we go with discrimination-nets? 

    Cunningham, Padraig; Smyth, Barry; Finn, Donal; Cahill, Eamonn (Trinity College Dublin, Department of Computer Science, 1992-10)
    In this paper we present a proposition and ponder a question. We propose that a useful perspective on analogical reasoning and CBR is to consider them on a continuum of abstraction of remindings. This is an alternative ...

  • Retrieving Reusable Design Cases: Exploiting Adaptation Knowledge in Design Reuse 

    Smyth, Barry; Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1994-11)
    Case-based reasoning has been identified as a potentially fruitful candidate technology with which to investigate the development of automated design systems. Two critical stages in case-based design are design retrieval ...

  • A Review of Active Learning and Co-Training in Text Classification 

    Davy, Michael (Trinity College Dublin, Department of Computer Science, 2005-11-04)
