3D object reconstruction using multiple views
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)3D object modelling from multiple view images has recently been of increasing interest in computer vision. Two techniques, Visual Hull and Photo Hull, have been extensively studied in the hope of developing 3D shape ... 
A diagnostic for the general linear model : an application to Time Series
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)An outlier is an observation which is thought to be unusual. The detection of such extreme values is an important issue. Developing a model based on data containing even a single outlier can seriously bias population ... 
A new method to implement Bayesian inference on stochastic differential equation models
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)Stochastic differential equations (SDEs) are widely used to model numerous reallife phenomena. However, transition densities of most of the SDE models used in practice are not known, making both likelihood based and ... 
A risk assessment tool for highly energetic breakup events during the atmospheric reentry
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)Most unmanned space missions end up with a destructive atmospheric reentry. From ten to forty percent of a reentering satellite’s mass may survive reentry and hit the Earth’s surface. This has the potential to be a ... 
Advances in Bayesian model development and inversion in multivariate inverse inference problems : with application to palaeoclimate reconstruction
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)An extremely challenging example of a multivariate inverse inference problem is the statistical reconstruction of palaeoclimate from fossil pollen data, which represents the motivating research problem considered in this ... 
An exploratory study of gender segregation in investment management in Ireland
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Despite the entry of women in recent years, Investment Management remains a male domain. The absence of women is most notable in the fund management suite and on the trading floor (the most lucrative sub sectors of the ... 
Bayesian approaches to contentbased image retrieval
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)This thesis addresses some issues in the relatively new field of ContentBased Image Retrieval. Contentbased image retrieval is a technique that uses the visual content of images to aid searches from large scale image ... 
Bayesian inference for misaligned irregular time series with application to palaeoclimate reconstruction
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)This thesis proposes new Bayesian methods to jointly analyse misaligned irregular time series. Temporal misalignment occurs wdien multiple irregularly spaced time series are considered together, or when the time periods ... 
Bayesian inference for short term traffic forecasting
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)In intelligent transport systems, short term traffic forecasting is one of the most important problems, reflecting the network state in the near future and feeding information to other application modules. Even though ... 
Bayesian kernel classification for high dimensional data with variable selection
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)High dimensional data sets, where the dimension of the measurements exceeds the number of samples, arise in many application domains. In particular, the development of genomic and proteomic technologies in the last decade ... 
Fast approximate inverse Bayesian inference in nonparametric multivariate regression with application to palaeoclimate reconstruction
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)Bayesian statistical methods often involve computationally intensive inference procedures. Sampling algorithms represent the current standard for fitting and testing models. Such methods, while flexible, are computationally ... 
Fast sequential parameter inference for dynamic state space models
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Many problems in science require estimation and inference on systems that generate data over time. Such systems, quite common in statistical signal processing, time series analysis and econometrics, can be stated in a ... 
L_ Inference for shape parameter estimation
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)In this thesis, we propose a method to robustly estimate the parameters that controls the mapping of a shape (model shape) onto another (target shape). The shapes of interest are contours in the 2D space, surfaces in the ... 
MCMC for inference on phasetype and masked system lifetime models
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Common reliability data consist of lifetimes (of censoring information) on all components and systems under examination. However, masked system lifetime data represents an important class of problems where the information ... 
Reliability updating in linear opinion pooling for multiple decision makers
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)Accurate information sources are vital prerequisites for good decision making. In this thesis we consider a multiple participant setting, where all decision makers (DMs) have a collection of neighbours with whom they share ... 
Statistical framework for multi sensor fusion and 3D reconstruction
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Multiview 3D reconstruction is an area of computer vision where multiple images are taken of an object and information in those images is used to generate a 3D model describing the shape and size of that object. The ... 
Statistical models for food authenticity
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)The authentication of food samples pose a particular problem for regulators. The routine testing of premium food products, most likely to be subject to manipulation for commercial gain, is only feasible if the testing ... 
Tracking the distribution of bugs across software release versions
(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 ... 
Utilisation of electronic fare collection data of urban bus operators with regard to transfer journeys and origin / destination estimation
(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
(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.
