    • On the Limitations of Memory Based Reasoning 

      Cunningham, Padraig; Smyth, Barry; Veale, Tony (Trinity College Dublin, Department of Computer Science, 1994-11)
      Memory-Based Reasoning (MBR) represents a radical new departure in AI research. Whereas work in symbolic AI is based on inference and knowledge representation MBR depends on using a large memory of examples as a reasoning ...

    • A Comparison of Incremental Case-Based Reasoning and Inductive Learning 

      Smyth, Barry; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 1994-11)
      This paper focuses on problems where the reuse of old solutions seems appropriate but the conventional CBR methodology is not adequate because a complete description of the new problem is not available to trigger ...

    • An Object-Oriented Approach for Replication Management 

      Gourhant, Yvon (Trinity College Dublin, Department of Computer Science, 1992-04-22)

    • Design Synthesis: A Model of Hierarchical Case-Based Reasoning 

      Smyth, Barry; Finn, Donal; Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1993-12)
      A variety of artificial intelligence techniques have been used in attempts to automate design synthesis tasks. Two common approaches are case-based and decompositional design. While powerful techniques in their own right, ...

    • Adaptation as a Selection Constraint On Analogical Mapping 

      Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1993-12)
      In any given analogy, there are potentially a large number of possible mapping interpretations. One of the key issues in analogy research is how one of these mappings comes to be selected as optimal and used as the basis ...

    • The Cognitive Processes Underlying Complex Analogies: Theoretical and Empirical Advances 

      Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1993-10)
      The psychological investigation of complex analogies (like the solar system / atom analogy) began in the late 1970s and in the intervening period has grown into a prototypical, area of Cognitive Science research. During ...

    • Constraints on Analogical Mapping: A Comparison of Three Models 

      Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1993-10)
      Three theories of analogy have been proposed which are supported by computational models and data from experiments on human analogical abilities. In this paper, we show how these theories can be unified within a common ...

    • Complexity of Adaptation in Real-World Case-Based Reasoning Systems 

      Smyth, Barry; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 1993-09)
      The essence of Case-Based Reasoning (CBR) as a problem solving paradigm is that solutions are generated by adapting the solutions of similar problems rather than solving the problem from first principles. In this paper ...

    • CBR in Scheduling: Reusing Solution Components 

      Cunningham, Padraig; Smyth, Barry (Trinity College Dublin, Department of Computer Science, 1995-06)
      In this paper we explore the reuse of components of known good schedules in new scheduling problems. This involves accumulating a case-base of good quality schedules, retrieving a case (or cases) similar to a new ...

    • Aontas: The CaberNet Technical Abstracts Service 

      Taylor, Paul (Trinity College Dublin, Department of Computer Science, 1995-10)
      CaberNet is the ESPRIT network of excellence in distributed systems consisting of several European research groups. CaberNet has industrial affiliates who receive regular information about the research activities of ...

    • An Improved Translation of SA/RT Specification Model to High-Level Timed Petri Nets 

      Nixon, Patrick (Trinity College Dublin, Department of Computer Science, 1995-10)
      Structured analysis methods for real-time systems (SA/RT) are widely accepted by the industrial world as a mature approach to real-time systems design. These methods use highly expressive graphical specification languages ...

    • On Adaptation in Analogy 

      Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1995-12)
      When people use analogies to solve problems they form an analogical mapping between two domains of knowledge. This mapping may support inferences by analogy that suggest a novel solution to a problem. Several factors ...

    • Epistemological Pitfalls in Metaphor Comprehension: A Comparison of Three Models and a New Theory of Metaphor 

      Veale, Tony; Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1995-12)
      [Introduction] If metaphor is to be viewed as a fundamental cognitive agency, as recent work suggests, what ramifications does this view have for a model of semantic memory? This paper presents a computational treatment ...

    • Physical Model Generation in PDE Analysis using Model-based Case-based Reasoning 

      Finn, Donal; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 1994-11)
      Model generation has emerged as a key task in engineering design and analysis. AI research in this area has focused on model based reasoning emphasising qualitative models in attempting to automate this process. In this ...

    • A Review of the Resource Management Task in ATM Networks 

      Naughton, Shane (Trinity College Dublin, Department of Computer Science, 1995-04)
      [Introduction] An ATM network is a connection-oriented, packet-switched network with the ability to transport heterogeneous services irrespective of characteristics across the same underlying physical network. ATM networks ...

    • Transfer Between Analogies: How Solving One Analogy Problem Helps to Solve Another 

      Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1995-04)
      This paper deals with transfer between analogies; with what people acquire from one analogy problem-solving episode that can be re-applied to a subsequent analogy, problem-solving episode. This issue must be resolved if ...

    • On Order Effects in Analogical Mapping: Predicting Human Error Using IAM 

      Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1995-04)
      The Incremental Analogy Machine (IAM) predicts that the order in which parts of an analogy are processed can affect the ease of analogical mapping. In this paper, the predictions of this model are tested in two ...

    • On the Automatic Generation of Case Libraries by Chunking Chess Games 

      Flinter, Stephen; Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1995-05)
