  • A unified framework for resource-bounded autonomous agents interacting with unknown environments 

    Ortega, Pedro Alejandro Jr (University of CambridgeDepartment of Engineering, 2011-07-12)
    The aim of this thesis is to present a mathematical framework for conceptualizing and constructing adaptive autonomous systems under resource constraints. The first part of this thesis contains a concise presentation of ...

  • Gaussian processes for state space models and change point detection 

    Turner, Ryan Darby (University of CambridgeDepartment of Engineering, 2012-02-07)
    This thesis details several applications of Gaussian processes (GPs) for enhanced time series modeling. We first cover different approaches for using Gaussian processes in time series problems. These are extended to the ...

  • Generalised Bayesian matrix factorisation models 

    Mohamed, Shakir (University of CambridgeDepartment of EngineeringSt John's College, 2011-03-15)
    Factor analysis and related models for probabilistic matrix factorisation are of central importance to the unsupervised analysis of data, with a colourful history more than a century long. Probabilistic models for matrix ...

  • R/BHC: fast Bayesian hierarchical clustering for microarray data 

    Savage, R; Heller, Katherine Ann; Xu, Y; Ghahramani, Zoubin; Truman, W; Grant, M; Denby, K; Wild, DL (BMC Bioinformatics 2009, 2009-08-06)
    Abstract Background Although the use of clustering methods has rapidly become one of the standard computational approaches in the literature of microarray gene expression data analysis, little attention has been paid to ...
