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
(North-Holland Pubs., Amsterdam, 1986) -
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 ... -
An evolutionary approach to automatic kernel construction
(2006)Abstract. Kernel-based learning presents a unified approach to machine learning problems such as classification and regression. The selection of a kernel and associated parameters is a critical step in the application of ... -
An evolutionary approach to formation control with mobile robots
(SciTePress Digital Library, 2016)The field of swarm robotics studies multi-robot systems, emphasising decentralised and self-organising behaviours that deal with limited individual abilities, local sensing and local communication. A robotic system needs ... -
Evolving collective behaviours in simulated kilobots
(Association for Computing Machinery, 2018-04-09)The field of Evolutionary Robotics has multiple common tasks and widely used benchmark activities such as navigation, obstacle avoidance, and phototaxis. We present an evolutionary approach to learning behaviours that ... -
Evolving Racetrack Knowledge in a Racing Game.
(21st National Conference on Artificial Intelligence and Cognitive Science, 2010-07-30)This paper discusses the use of a Genetic Algorithm (GA) to evolve waypoint-based racing lines for computer-controlled cars in an online game. One goal is the reduction of developer effort, in order to automatically produce ... -
Examining the impact of neutrality on genetic algorithm population evolution
(SciTePress Digital Library, 2015-11-12)This paper examines the introduction of neutrality as proposed by Kimura (Kimura, 1968) into the genotype-phenotype mapping of a Genetic Algorithm (GA). The paper looks at the evolution of both a simple GA (SGA) and a ... -
Examining the use of a non-trivial fixed genotype-phenotype mapping in genetic algorithms to induce phenotypic variability over deceptive uncertain landscapes
(IEEE, 2011-06-05)In nature, living organisms can be viewed as the product of their genotype-phenotype mapping (GP-map). This paper presents a GP-map loosely based on the biological phe- nomena of transcription and translation, to create a ... -
Experimental Assessment of an Emotion Tracking Software Agent (ETA) for Assisting Communicative Interactions of Multitasking Users in Groupware
(Eurosis, 2011-08-22)Interactions such as discussion and negotiation in face-to-face work contexts strongly rely on non-verbal feedback. Such feedback provides indications of important negotiation states such as agreement or disagreement and ... -
Follow flee: A contingent mobility strategy for the spatial prisoner's dilemma
(Springer Verlag, 2016-08-10)This paper presents results from a series of experimental simulations comparing the performances of mobile strategies of agents participating in the Spatial Prisoner's Dilemma game. The contingent movement strategies Walk ... -
A Framework for Digital Wide-Area Survey from Aerial Photographs
(Wordwell Ltd., 1998)Despite the potential offered by modern computer technology to the labour-intensive work of 'Aerial Archaeology', few applications have been published. Where developments have been made, they have tended to be carried out ...
