    • Topics in unsupervised learning 

      McNicholas, Paul David (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)
      Two topics in unsupervised learning are reviewed and developed; namely, model-based clustering and association rule mining. A new family of Gaussian mixture models, with a parsim onious covariance structure, is introduced. ...

    • Tracking the distribution of bugs across software release versions 

      Ó Ríordáin, Seán (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)
      Real software systems always contain bugs and the question on every release manager’s mind coming up to a release centres around how many undiscovered bugs there still remain. This work looks at one model, (Goel and ...

    • Univariate time series modelling and forecasting using TSMARS 

      Keogh, Gerard (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)
      This thesis studies threshold nonlinearity in time series using TSMARS, a time series extension of the Multivariate Adaptive Regression Splines (MARS) procedure of Friedman (1991a). MARS is model free and can detect and ...

    • Utilisation of electronic fare collection data of urban bus operators with regard to transfer journeys and origin / destination estimation 

      Hofmann, Markus (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)
      The understanding of an urban public transport network from an operational point of view and the understanding of passenger’s travel patterns become increasingly important due to the growing complexity of most networks. ...

    • Variational Bayes approximation for inverse regression problems 

      Vatsa, Richa (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)
      Inverse regression is a tool to predict an unknown explanatory variable for given observations of a response variable in a regression problem. The prediction problem is usually carried out in two stages: firstly, to fit ...

    • Visual attention using 2D & 3D displays 

      Zdziarski, Zbigniew (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)
      In the past three decades, robotists and computer vision scientists, inspired by psychological and neurophysiological studies, have developed many computational models of attentions (CMAs) that mimic the behaviour of the ...
