Discretization of numerical data is one of the most influential data preprocessing tasks in knowledge discovery and data mining. The purpose of attribute discretization is to find concise data representations as categories which are adequate for the learning task retaining as much information in the original continuous attribute as possible. In this article, we present an updated overview of di...

Student learning style differences have been widely researched in both traditional face-to-face and online learning environments (Irani, Scherler & Harrington, 2003; Steinbronn, 2007; Williamson & Watson, 2007; Ugur, Akkoyunlu & Kurbanoglu, 2001). After conducting a literature review of adult student learning styles and teaching method analysis, it became apparent that there was not a significa...

Though competitive analysis has been a very useful performance measure for the quality of online algorithms, it is recognized that it sometimes fails to distinguish between algorithms of different quality in practice. A number of alternative measures have been proposed, but, with a few exceptions, these have generally been applied only to the online problem they were developed in connection wit...

This document is dedicated to my parents who persuaded me to do my masters' and funded my education. iv ACKNOWLEDGMENTS I would like to take this opportunity to thank everyone who, directly or indirectly, helped me complete this thesis. First, I would like to thank my committee chair, Dr. Debra Harris, for all the encouragement and guidance rendered to me during my course of study. I would also...

This paper looks at factors affecting student satisfaction with and perceived learning from asynchronous online learning. It reports on an empirical investigation that explored relationships between student perceptions and course design factors in seventythree SUNY Learning Network courses in the spring, 1999 semester. The study found that three, and only three, general factors – clarity of des...

This thesis explores the use of invariant features for learning sprites from image sequences, and for recognising object categories in images. A popular framework for the interpretation of image sequences is the layers or sprite model of e.g. Wang and Adelson (1994), Irani et al. (1994). Jojic and Frey (2001) provide a generative probabilistic model framework for this task, but their algorithm ...
