Bayesian factor analysis using Gaussian mixture sources, with applicatin to separation of the cosmic microwave background
WILSON, SIMON (2010)In this paper a fully Bayesian factor analysis model is developed that assumes a very general model for each factor, namely the Gaussian mixture. We discuss the cases where factors are both independent and dependent. ... -
Bayesian inference for reliability of systems and networks using the survival signature
WILSON, SIMON (2014)The concept of survival signature has recently been introduced as an alternative to the signature for reliability quantifcation of systems. While these two concepts are closely related for systems consisting of a single ... -
Brain activity detection by estimating the signal-to-noise ratio of fMRI time series using dynamic linear models
WILSON, SIMON (2015)This work shows an example of the application of Bayesian dynamic linear models in fMRI analysis. Estimating the error variances of such a model, we are able to obtain samples from the posterior distribution of the ... -
Considerations on the UK Re-Arrest Hazard Data Analysis (How Model Selection Can Alter Conclusions for Policy Development)
WILSON, SIMON; HOULDING, BRETT (2011)The offence risk posed by individuals who are arrested, but where subsequently no charge or caution is administered, has been used as an argument for justifying the retention of such individuals? DNA and identification ... -
Considerations on the UK re-arrest hazard rate analysis
WILSON, SIMON; HOULDING, BRETT (2011)The offence risk posed by individuals who are arrested, but where subsequently no charge or cau- tion is administered, has been used as an argument for justifying the retention of such individuals? DNA and identification ... -
Estimating production test properties from test measurement data
WILSON, SIMON (2011)A complex sequence of tests on components and the system is a part of many manufacturing processes. Statistical imperfect test and repair models can be used to derive the properties of such test sequences but require model ... -
Factors influencing when species are first named and estimating global species richness
WILSON, SIMON; HOULDING, BRETT (2015)Estimates of global species richness should consider what factors influence the rate of species discovery at global scales. However, past studies only considered regional scales and/or samples representing <0.4% of all ... -
Modeling and adapting production environmental stress testing
WILSON, SIMON (2009)This study describes the production sampling environmental stress test (PSEST) process and the offline analysis conducted. Some of the key characteristics and parameters of the test are outlined. The analytical process ... -
Predicting the number of known and unknown species in European seas using rates of description
WILSON, SIMON (2011)Aim? In this paper, we compare species description rates to predict the numbers of undescribed species. These data are used to discuss the merits of various attempts to estimate species richness in the oceans. Location? ... -
Predicting total global species richness using rates of species description and estimates of taxonomic effort
WILSON, SIMON; HOULDING, BRETT (2012)We found that trends in the rate of description of 580,000 marine and terrestrial species, in the taxonomically authoritative World Register of Marine Species and Catalogue of Life databases, were similar until the 1950s. ... -
A probability model of system downtime with implications for optimal warranty design
WILSON, SIMON; HOULDING, BRETT (2009)Traditional approaches to modeling the availability of a system often do not formally take into account uncertainty over the parameter values of the model. Such models are then frequently criticised because the ... -
Short-term traffic flow forecasting with A-SVARMA
WILSON, SIMON; GHOSH, BIDISHA (2013)Short-term Traffic Flow Forecasting (STFF), the process of predicting future traffic conditions based on historical and real-time observations, is an essential aspect of Intelligent Transportation Systems (ITS). The existing ... -
Using Storm for scaleable sequential statistical inference
WILSON, SIMON (2014)This article describes Storm, an environment for doing streaming data analysis. Two examples of sequential data analysis | computation of a running summary statistic and sequential updating of a posterior distribution | ... -
The variational Bayes method for inverse regression problems with an application to the palaeoclimate reconstruction
WILSON, SIMON (2010)The palaeoclimate reconstruction problem is described as an example of inverse regression problems. In the reconstruction problem, past climate is inferred using pollen data. Modern data is used to build a regression ...
