Bayesian ANN Classifier for ECG Arrhythmia Diagnostic System: A Comparison Study
(2005)Abstract¿This paper outlines a system for detection of cardiac arrhythmias within ECG signals, based on a Bayesian Artificial Neural Network (ANN) classifier. The Bayesian (or Probabilistic) ANN Classifier is built by the ... -
The benefits of system dynamics simulation for sustainability education
(System Dynamics Society, 2021-07-26)Education for Sustainable Development (ESD) is vital to the success of the United Nation¿s Sustainable Development Goals, yet it has so far proved difficult to implement. One reason for this is the systemic understanding ... -
Business Modelling to Support the Development of Integrated Process Support Systems in the Extended Enterprise
(1999)Recent years have witnessed rapid advances in the areas of Business Process Reengineering(BPR) and Software Engineering. In order for BPR to work, successful deployment of Information Technology is imperative, with the ... -
Classification of a Target Analyte in Solid Mixtures using Principal Component Analysis, Support Vector Machines and Raman Spectroscopy
(2005)The quantitative analysis of illicit materials using Raman spectroscopy is of widespread interest for law enforcement and healthcare applications. One of the difficulties faced when analysing illicit mixtures is the ... -
Co-evolutionary analysis: a policy exploration method for system dynamics models
(System Dynamics Society / Wiley, 2012-10-22)In system dynamics (SD), complex nonlinear systems can generate a wide range of possible behaviours that frequently require search and optimization algorithms in order to explore optimal policies. Within the SD literature, ... -
Collaborative Virtual Environments to Support Communication and Community in Internet-Based Distance Education
(jite.org, 2002)In this paper we discuss the use of modern information and communication technologies for distance education (DE) purposes. We argue that current technologies and implementations do not adequately support the key concepts ... -
A comparison of automatic labelling approaches for sentiment analysis
(SciTePress, 2022-07-11)Labelling a large quantity of social media data for the task of supervised machine learning is not only time-consuming but also difficult and expensive. On the other hand, the accuracy of supervised machine learning models ... -
A Comparison of Petri Net and System Dynamics Approaches for Modelling Dynamic Feedback Systems
(2006)Petri nets are a valuable tool that can be used to simulate workflow systems. They are based on a state-transition approach, and in common with discrete event simulation, events can be scheduled to fire at different time ... -
Cyclic dominance in the spatial coevolutionary optional prisoner's dilemma game
(CEUR-WS.org, 2016-09-20)This paper studies scenarios of cyclic dominance in a coevolutionary spatial model in which game strategies and links between agents adaptively evolve over time. The Optional Prisoner’s Dilemma (OPD) game is employed. ... -
A Data-Driven Exploration of Factors Affecting Student Performance in a Third-Level Institution
(2008)This paper describes an application of data mining techniques to the analysis of student academic records, collected at Limerick Institute of Technology, with the goal of acquiring clearer, evidence-based ... -
Digital elevation modelling of individual monuments from aerial photographs
(John Wiley & Sons, 1999)Digital elevation models (DEM) are crucial data products for a variety of geographic applications, and their generation directly from digitized stereopairs of vertical aerial photographs has recently been accomplished. ... -
Diversifying techniques and neutrality in genetic algorithms
(SciTePress Digital Library, 2016)This paper examines the implicit maintenance of diversity within a population through the inclusion of a layered genotype-phenotype map (GP-map) in a Genetic Algorithm (GA), based on the principal of Neutral theory. The ... -
Economic analysis of short-rotation forests for energy in Ireland

The Effect of Principal Component Analysis on Machine Learning Accuracy with High Dimensional Spectral Data
(2005)The classi¿cation of high dimensional data, such as images, gene-expression data and spectral data, poses an interesting challenge to machine learning, as the presence of high numbers of redundant or highly correlated ... -
Emotion Tracking for Remote Conferencing Applications using Neural Networks.
(The 21st National Conference on Artificial Intelligence and Cognitive Science, 2010-08-31)In face-to-face work, discussion and negotiation relies strongly on non-verbal feedback, which provides important clues to negotiation states such as agreement/disagreement and understanding/confusion, as well as indicating ... -
An empirical study of the impact of systems thinking and simulation on sustainability education
(MDPI, 2021-12-30)Education for sustainable development (ESD) is considered vital to the success of the United Nations¿ sustainable development goals. Systems thinking has been identified as a core competency that must be included in ESD. ... -
Equation-based policy optimization for agent-oriented system dynamics models
(Wiley Blackwell, 2008-01-01)Within system dynamics, optimization has played an important role in identifying the best range of parameter values for policies in any given model. Optimal solutions focus on discovering the best combination of model ... -
The Evolution of a Kernel-Based Distance Metric for k-NN Regression
(2007)k-Nearest Neighbours (k-NN) is a well understood and widely-used approach to classification and regression problems. In many cases, such applications of k-NN employ the standard Euclidean distance metric for the determination ... -
Evolution of cooperation in N-player social dilemmas: The importance of being mobile
(SciTePress Digital Library, 2016)This paper addresses issues regarding the emergence of cooperation in evolutionary, spatial game-theoretic simulations. In the model considered, agents participate in a social dilemma with their neighbours and have the ... -
