Activity theory: another perspective on task analysis. (2003)
Book Chapter
Turner, P., & McEwan, T. (2003). Activity theory: another perspective on task analysis. In D. Diaper, & N. Stanton (Eds.), The Handbook of Task Analysis for Human-Computer Interaction (423-444). CRC Press

In this chapter, we introduce activity theory, describing its origins and its principal researchers and thinkers. We stress its descriptive power and its usefulness in defining uniquely a unit of analysis for work. We contrast its development with th...

Learning technology research in practice: Reflections from the field. (2003)
Presentation / Conference Contribution
Cairncross, S., Mannion, M., & McEwan, T. (2003, September). Learning technology research in practice: Reflections from the field

Research into the effectiveness of new learning technologies is needed. However education research is complex and challenging. In this paper we explore problems associated with different methodological approaches. In particular the value of controll...

A comparison of the performance of different metaheuristics on the timetabling problem. (2003)
Presentation / Conference Contribution
Rossi-Doria, O., Sampels, M., Birattari, M., Chiarandini, M., Dorigo, M., Gambardella, L. M., Knowles, J., Manfrin, M., Mastrolilli, M., Paechter, B., Paquete, L., & Stutzle, T. (2002, August). A comparison of the performance of different metaheuristics on the timetabling problem

The main goal of this paper is to attempt an unbiased comparison of the performance of straightforward implementations of five different metaheuristics on a university course timetabling problem. In particular, the metaheuristics under consideration... Read More about A comparison of the performance of different metaheuristics on the timetabling problem..

Understanding neural computation in terms of pattern languages (2003)
Presentation / Conference Contribution
András, P. (2003). Understanding neural computation in terms of pattern languages. In Proceedings of the International Joint Conference on Neural Networks, 2003 (1385-1390)

There is some experimental evidence that the neural information processing in some small neural systems with complex behaviour (e.g., olfactory bulb, crab stomatogastric ganglion) can be best described in terms of activity patterns. Recently the patt... Read More about Understanding neural computation in terms of pattern languages.

Attempting to Reduce the Vanishing Gradient Effect through a novel Recurrent Multiscale Architecture (2003)
Presentation / Conference Contribution
Squartini, S., Hussain, A., & Piazza, F. (2003, July). Attempting to Reduce the Vanishing Gradient Effect through a novel Recurrent Multiscale Architecture. Presented at International Joint Conference on Neural Networks, 2003, Portland, OR, US

This paper proposes a possible solution to the vanishing gradient problem in recurrent neural networks, occurring when such networks are applied to solving tasks where detection of long term dependencies is required. The main idea consists of pre-pro... Read More about Attempting to Reduce the Vanishing Gradient Effect through a novel Recurrent Multiscale Architecture.

Using curves to enhance parallel coordinate visualisations (2003)
Presentation / Conference Contribution
Graham, M., & Kennedy, J. (2003, July). Using curves to enhance parallel coordinate visualisations. Presented at Seventh International Conference on Information Visualization, 2003. IV 2003., London, UK

This paper introduces a number of refinements to the Parallel Coordinates visualisation metaphor for multi-dimensional data. Firstly, the traditional set of poly-lines are replaced with a collection of smooth curves across the attribute axes, allowin...

Learning a procedure that can solve hard bin-packing problems: a new GA-based approach to hyperheuristics. (2003)
Presentation / Conference Contribution
Ross, P., Marin-Blazquez, J. G., Schulenburg, S., & Hart, E. (2003). Learning a procedure that can solve hard bin-packing problems: a new GA-based approach to hyperheuristics.

The idea underlying hyper-heuristics is to discover some combination of familiar, straightforward heuristics that performs very well across a whole range of problems. To be worthwhile, such a combination should outperform all of the constituent heur...
