Non-Contact Surface Geometry Measurement Techniques
(Trinity College Dublin, Department of Computer Science, 1999-09)It is often necessary to be able to create computer models from physical objects. This is often done for the purposes of reverse engineering, or archival. Many of the contact methods, such as callipers or Coordinate Measuring ... -
Object Recognition and Active Learning in Microscope Images
(Trinity College Dublin, Department of Computer Science, 2006-07-26)Microscopic analysis forms an integral part of many scientific studies. It is a task which requires great expertise and care. However, it can often be an extremely repetitive and laborious task. In some cases many ... -
An Object-Oriented Approach for Replication Management
(Trinity College Dublin, Department of Computer Science, 1992-04-22) -
Objects, Components and the Virtual Enterprise
(Trinity College Dublin, Department of Computer Science, 1999-02)We are currently witnessing a convergence of several threads of technology and business imperatives. The idea of a virtual enterprise (VE) ? a business built from both organizationally and geographically distributed units ... -
On Adaptation in Analogy
(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 ... -
On balancing client - server load in intelligent web-based applications involving dialog
(Trinity College Dublin, Department of Computer Science, 1999-04)With the explosive growth of the Internet have come problems of increased server load and network latency. This means that systems that require interchange of data between server and client over the network can be slow to ... -
On Order Effects in Analogical Mapping: Predicting Human Error Using IAM
(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
(Trinity College Dublin, Department of Computer Science, 1995-05)As a research topic computer game playing has contributed problems to AI that manifest exponential growth in the problem space. For the most part, in games such as chess and checkers these problems have been surmounted ... -
On the Limitations of Memory Based Reasoning
(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 ... -
On the use of CBR in optimisation problems such as the TSP
(Trinity College Dublin, Department of Computer Science, 1995-06)The particular strength of CBR is normally considered to be its use in weak theory domains where solution quality is compiled into cases and is reusable. In this paper we explore an alternative use of CBR in optimisati ... -
On the use of Information Systems Research Methods in Data Mining
(Trinity College Dublin, Department of Computer Science, 2005) -
An on-line evaluation framework for recommender systems
(Trinity College Dublin, Department of Computer Science, 2002-04)Several techniques are currently used to evaluate recommender systems. These techniques involve off-line analysis using evaluation methods from machine learning and information retrieval. We argue that while off-line ... -
Ontology Discovery for the Semantic Web Using Hierarchical Clustering
(Trinity College Dublin, Department of Computer Science, 2002-04)According to a proposal by Tim Berners-Lee, the World Wide Web should be extended to make a Semantic Web where human understandable content is structured in such a way as to make it machine processable. Central ... -
Overfitting and Diversity in Classification Ensembles based on Feature Selection
(Trinity College Dublin, Department of Computer Science, 2000-02)This paper addresses Wrapper-like approaches to feature subset selection and the production of classifier ensembles based on members with different feature subsets. The paper starts with the observation that if an ... -
Overfitting in Wrapper-Based Feature Subset Selection: The Harder You Try the Worse it Gets
(Trinity College Dublin, Department of Computer Science, 2005-01-28)In Wrapper based feature selection, the more states that are visited during the search phase of the algorithm the greater the likelihood of finding a feature subset that has a high internal accuracy while generalizing ... -
Overview of Appearance Based Methods in Computer Vision
(Trinity College Dublin, Department of Computer Science, 1999-10-06)Appearance based methods turned traditional computer vision approaches to object recognition upside down. Instead of going from image to 3D model and matching that model to models of know objects, appearance based methods ... -
Overview of the Amadeus Project
(Trinity College Dublin, Department of Computer Science, 1992-02)An introduction to the Amadeus v1.0 environment for distributed and persistent programming in C++ is described. -
Partial Outsourcing: A New Paradigm for Access Control
(Trinity College Dublin, Department of Computer Science, 2003-04-28)Various security models have been proposed in recent years for different purposes. Each of these aims to ease administration by introducing new types of security policies and models. This increases the complexity a system ... -
Partition Anticipation for Wireless Local Area Networks
(Trinity College Dublin. Department of Computer Science, 2002-09)Wireless networks introduce new possibilities for computer networking. They also bring some new problems, while enhancing some already established ones. One new problem is a network's increased sensitivity to its environment, ...
