(Thesis, Master of Science, 2013)Vocabulary mismatch is an impediment to responding to user queries with relevant results. Stemmers solve this problem by conflating terms with similar spellings. In this thesis we use machine learning to create a stemmer ... -
(Thesis, Master of Science, 1999)

(Thesis, Master of Science, 2006)Disambiguating an utterance occurring in a dialogue context is a complex task, which requires input from many different sources of information -- some syntactic, some semantic, and some pragmatic. The central question ... -
(Thesis, Master of Science, 2012)Various researchers have used one hidden layer neural networks (weighted sums of sigmoids) to find the unknown solutions of partial differential equations. They are embedded within an energy function that describes the ... -
(Thesis, Master of Science, 2012)A common problem in computer vision is to match corresponding points between images. The success of computer vision has usually relied on having good feature representations, which are usually hand-crafted and thus require ... -
(Thesis, Doctor of Philosophy, 2012)This thesis presents a study in the area of computer assisted language learning systems. The study focusses on the topic of automatic correction of student errors. In the thesis, I will describe a novel statistical model ... -
(Thesis, Doctor of Philosophy, 2012)With the development of deep belief nets, the empirical evidence supporting a link between deep architecture neural networks and generalisation with respect to classification has been mounting. An analytical proof of this ... -
(Thesis, Doctor of Philosophy, 2012)This thesis presents the design and implementation of our novel hybrid software DSM system. We call our system hybrid home-based EAC (HHEAC) since the system implements our novel exclusive access consistency model (EAC) ... -
(Thesis, Master of Science, 2011)The automatic generation of useful hyperlinks has been a topic of interest in the field of information retrieval for several years, but no existing method for evaluating the quality of the generated hyperlinks has yet been ... -
(Thesis, Master of Science, 2011)The new user problem is a problem that all collaborative filtering systems will face. How do we make recommendations when we do not know what the user likes? This thesis provides an overview of collaborative filtering ... -
(Thesis, Doctor of Philosophy, 2011)For most animals, locomotion is essential for survival, and it is advantageous to do this efficiently and with minimal neural control. Research has shown that efficient walking is possible without control, resulting purely ... -
(Thesis, Master of Science, 2011)Reinforcement learning (RL) problems are a fundamental part of machine learning theory, and neural networks are one of the best known and most successful general tools for solving machine learning problems. Despite this, ... -
(Thesis, Master of Science, 2009)Human infants begin to produce speech at the beginning of the second year of life. Some theories propose that language is acquired by simply recognising statistical properties in linguistic input. Other hypotheses consider ... -
(Dissertation, Master of Science, 1991)Most modern companies probably could not function without a database management system (DBMS). Although current DBMSs are becoming increasingly sophisticated, they are still deficient in several areas. One of these areas ... -
(Dissertation, Master of Science, 1997)Alliance Textiles in collaboration with the Department of Computer Science at the University of Otago developed a computer based knitwear design program that enables a member of the public to easily and quickly design a ... -
(Discussion Paper, 2001)This paper proposes a novel View-based Consistency model for Distributed Shared Memory. A view is a set of ordinary data objects that a processor has the right to access in a data-race-free program. The View-based Consistency ... -
(Discussion Paper, 1995)The concept of an intelligent software agent has emerged from its origins in artificial intelligence laboratories to become an important basis for the development of distributed systems in the mainstream computer science ...
