USE OF BAYESIAN NETWORKS AS JUDGEMENT CALCULUS IN A KNOWLEDGE BASED IMAGE INTERPRETATION SYSTEM
Image Interpretation Semantic Net Bayesian Network Multitemporal Analysis
2014/12/31
The increasing amount of remotely sensed imagery from multiple platforms requires efficient analysis techniques. The presented image interpretation system tries to automate the analysis of multisensor...
A Bayesian approach to the semi-analytic model of galaxy formation: methodology
galaxy formation methodology
2014/12/22
We believe that a wide range of physical processes conspire to shape the observed galaxy population but we remain unsure of their detailed interactions. The semi-analytic model (SAM) of galaxy formati...
FLEXINVERT: an atmospheric Bayesian inversion framework for determining surface fluxes of trace species using an optimized grid
atmospheric Bayesian inversion framework optimized grid
2014/12/19
We present a new modular Bayesian inversion
framework, called FLEXINVERT, for estimating the surface
fluxes of atmospheric trace species. FLEXINVERT can be
applied to determine the spatio-tem...
Simultaneously assimilating multivariate data sets into the two-source evapotranspiration model by Bayesian approach: application to spring maize in an arid region of northwestern China
Simultaneously assimilating multivariate data sets two-source evapotranspiration model Bayesian approach spring maize in an arid region of northwestern China
2014/12/19
Based on direct measurements of half-hourly canopy evapotranspiration (ET; W m−2) using the eddy covariance (EC) system and daily soil evaporation (E; mm day−1) using microlysimeters over ...
Learning the Structure of Bayesian Networks with Constraint Satisfaction
Bayesian networks Constraint satisfaction Constraint-based Structure learning
2014/12/18
A Bayesian network is graphical representation of the probabilistic relationships among set of variables and can be used to encode expert knowledge about uncertain domains. The structure of this model...
A Bayesian approach to the semi-analytic model of galaxy formation
Pure sciences Galaxy population Diverse data sources Galaxy evolution Galaxy formation
2014/12/9
It is believed that a wide range of physical processes conspire to shape the observed galaxy population but it remains unsure of their detailed interactions. The semi-analytic model (SAM) of galaxy fo...
Bayesian Anatomy of Galaxy Structure
Bayesian Statistics Galaxy Markov chain Monte Carlo Morphology
2014/12/9
In this thesis I develop Bayesian approach to model galaxy surface brightness and apply it to a bulge-disc decomposition analysis of galaxies in near-infrared band, from Two Micron All Sky Survey (2MA...
Bayesian Distance Metric Learning on i-vector for Speaker Verification
i-vector score normalization distance metric learning channel compensation limited training utterances
2014/11/27
This paper presents a new speaker verification system based on i-vector modeling as a feature extractor. In this modeling, we explore the distance constraints between i-vector pairs from the same spea...
A Nonparametric Bayesian Approach to Acoustic Model Discovery
A Nonparametric Bayesian Approach Acoustic Model Discovery
2014/11/27
We investigate the problem of acoustic modeling in which prior language-specific knowledge and transcribed data are unavailable. We present an unsupervised model that simultaneously segments the speec...
Hidden Feature Models for Speech Recognition Using Dynamic Bayesian Networks
Hidden Feature Models Speech Recognition Dynamic Bayesian Networks
2014/11/27
In this paper, we investigate the use of dynamic Bayesian networks (DBNs) to explicitly represent models of hidden features,such as articulatory or other phonological features, for automatic speech re...

A Bayesian analysis of the spatial concentration of individual wealth in the US North during the nineteenth century
Bayesian historical wealth
2014/11/26
Background: Kin effects can be difficult to distinguish from those of spatial proximity, since kin tend to live close to each other. Thus, past research showing correlations between the wealth of rela...
The age pattern of increases in mortality affected by HIV: Bayesian fit of the Heligman-Pollard Model to data from the Agincourt HDSS field site in rural northeast South Africa
AIDS/HIV Bayesian inference life expectancy South AfricaAIDS/HIV Bayesian inference life expectancy South Africa
2014/11/25
Background: We investigate the sex-age-specific changes in the mortality of a prospectively monitored rural population in South Africa. We quantify changes in the age pattern of mortality efficiently ...

childbearing age fertility first birth geo-additive models Nigeria prior and posterior distributions spatial analysis
2014/11/24
Background: The age at which childbearing begins influences the total number of children a woman bears throughout her reproductive period, in the absence of any active fertility control. For countries...
