  • Data measures that characterise classification problems 
    Van der Walt, Christiaan Maarten (University of Pretoria, 2008-09-09)
    We have a wide-range of classifiers today that are employed in numerous applications, from credit scoring to speech-processing, with great technical and commercial success. No classifier, however, exists that will outperform ...
  • Eukaryotic RNA Polymerase II start site detection using artificial neural networks 
    Myburgh, Gerbert (University of Pretoria, 2007-01-24)
    An automated detection process for Eukaryotic ribonucleic acid (RNA) Polymerase II Promoter is presented in this dissertation. We employ an artificial neural network (ANN) in conjunction with features that were selected ...
  • Network configuration improvement and design aid using artificial intelligence 
    Van Graan, Sebastian Jan (University of Pretoria, 2008-09-09)
    This dissertation investigates the development of new Global system for mobile communications (GSM) improvement algorithms used to solve the nondeterministic polynomial-time hard (NP-hard) problem of assigning cells to ...
  • Phoneme duration modelling for speaker verification 
    Van Heerden, Charl Johannes (University of Pretoria, 2009-06-29)
    Higher-level features are considered to be a potential remedy against transmission line and cross-channel degradations, currently some of the biggest problems associated with speaker verification. Phoneme durations in ...
  • Pronunciation modelling and bootstrapping 
    Davel, Marelie Hattingh (University of Pretoria, 2006-10-11)
    Bootstrapping techniques have the potential to accelerate the development of language technology resources. This is of specific importance in the developing world where language technology resources are scarce and linguistic ...
  • Protein secondary structure prediction using amino acid regularities 
    Senekal, Frederick Petrus (University of Pretoria, 2009-04-08)
    The protein folding problem is examined. Specifically, the problem of predicting protein secondary structure from the amino acid sequence is investigated. A literature study is presented into the protein folding process ...
  • Sparse coding for speech recognition 
    Smit, Willem Jacobus (University of Pretoria, 2008-12-11)
    The brain is a complex organ that is computationally strong. Recent research in the field of neurobiology help scientists to better understand the working of the brain, especially how the brain represents or codes external ...
  • Text-based language identification for the South African languages 
    Botha, Gerrit Reinier (University of Pretoria, 2008-09-09)
    We investigate the factors that determine the performance of text-based language identification, with a particular focus on the 11 official languages of South Africa. Our study uses n-gram statistics as features for ...
