  • A new approach to fitting linear models in high dimensional spaces

    Wang, Yong (The University of Waikato, 2000)
    This thesis presents a new approach to fitting linear models, called “pace regression”, which also overcomes the dimensionality determination problem. Its optimality in minimizing the expected prediction loss is theoretically ...

  • A Predictive Model for the Parallel Processing of Digital Libraries

    Thompson, John Matthew (University of Waikato, 2015)
    The computing world is facing the problem of a seemingly exponential increase in the amount of raw digital data, and the speed at which it is being collected, is eclipsing our ability to manage it manually. Combine this ...

  • Applying Wikipedia to Interactive Information Retrieval

    Milne, David N. (University of Waikato, 2010)
    There are many opportunities to improve the interactivity of information retrieval systems beyond the ubiquitous search box. One idea is to use knowledge bases—e.g. controlled vocabularies, classification schemes, thesauri ...

  • Augmenting Autobiographical Memory: An Approach Based on Cognitive Psychology

    Schweer, Andrea (University of Waikato, 2011)
    This thesis investigates how an interactive software system can support a person in remembering their past experiences and information related to these experiences. It proposes design recommendations for augmented ...

  • Automating vocabulary tests and enriching online courses for language learners

    König, Jemma Lynette (The University of Waikato, 2019)
    The past decade has seen a massive growth in online academic courses, most of which are offered in the English language. However, although more people speak English as their second language than as their first, online ...

  • Computing the fast Fourier transform on SIMD microprocessors

    Blake, Anthony Martin (University of Waikato, 2012)
    This thesis describes how to compute the fast Fourier transform (FFT) of a power-of-two length signal on single-instruction, multiple-data (SIMD) microprocessors faster than or very close to the speed of state of the art ...

  • Concept-based Text Clustering

    Huang, Lan (University of Waikato, 2011)
    Thematic organization of text is a natural practice of humans and a crucial task for today's vast repositories. Clustering automates this by assessing the similarity between texts and organizing them accordingly, grouping ...

  • Coordinating knowledge to improve optical music recognition

    McPherson, John (The University of Waikato, 2006)
    Optical Music Recognition (OMR) is the process of automatically processing and understanding an image of a music score. This process involves various distinct phases to transform the image into primitive shapes, musical ...

  • Learner Modelling for Individualised Reading in a Second Language

    Walmsley, Michael (University of Waikato, 2015)
    Extensive reading is an effective language learning technique that involves fast reading of large quantities of easy and interesting second language (L2) text. However, graded readers used by beginner learners are expensive ...

  • Lossless document image compression

    Inglis, Stuart J. (The University of Waikato, 1999)
    Document image compression reduces the storage requirements for digitised books or documents by using characters as the fundamental unit of compression. Compression gains can be achieved by identifying regions that contain ...

  • N-gram models of agreement in language

    Smith, Anthony Clive (The University of Waikato, 2000)
    Conventional n-gram language models are well-established as powerful yet simple mechanisms for characterising language structure when low data complexity is the primary objective. Much of their predictive power can be ...

  • Patterns of Change: Can modifiable software have high coupling?

    Taube-Schock, Craig (University of Waikato, 2012)
    There are few aspects of modern life that remain unaffected by software, and as our day-to-day challenges change, so too must our software. Software systems are complex, and as they grow larger and more interconnected, ...

  • Privacy-preserving encoding for cloud computing

    Will, Mark Antony (The University of Waikato, 2019)
    Information in the cloud is under constant attack from cyber criminals as profitability increases; user privacy is also at risk with data being mined for monetary value – the new gold. A single leak could have devastating ...

  • Pruning decision trees and lists

    Frank, Eibe (The University of Waikato, 2000)
    Machine learning algorithms are techniques that automatically build models describing the structure at the heart of a set of data. Ideally, such models can be used to predict properties of future data points and people can ...

  • Realistic electronic books

    Liesaputra, Veronica (University of Waikato, 2010)
    People like books. They are convenient and can be accessed easily and enjoyably. In contrast, many view the experience of accessing and exploring electronic documents as dull, cumbersome and disorientating. This thesis ...

  • Scalable Text Mining with Sparse Generative Models

    Puurula, Antti (University of Waikato, 2015)
    The information age has brought a deluge of data. Much of this is in text form, insurmountable in scope for humans and incomprehensible in structure for computers. Text mining is an expanding field of research that seeks ...

  • Supporting Collocation Learning

    Wu, Shaoqun (University of Waikato, 2010)
    Collocations are of great importance for second language learners. Knowledge of them plays a key role in producing language accurately and fluently. But such knowledge is difficult to acquire, simply because there is so ...
