Algoritmo ejeção-absorção metropolizado para segmentação de imagens
(Universidade Federal de São Carlos, 2014-12-19)
We proposed a new split-merge MCMC algorithm for image segmentation. We describe how an image can be subdivided into multiple disjoint regions, with each region having an associated latent indicator variable. The latent ...
Extensões dos modelos de sobrevivência referente a distribuição Weibull
(Universidade Federal de São Carlos, 2014-03-07)
In this dissertation, two models of probability distributions for the lifetimes until the occurrence of the event produced by a specific cause for elements in a population are reviewed. The first revised model is called ...
Distribuição de Poisson bivariada aplicada à previsão de resultados esportivos
(Universidade Federal de São Carlos, 2014-04-23)
The modelling of paired counts data is a topic that has been frequently discussed in several threads of research. In particular, we can cite bivariate counts, such as the analysis of sports scores. As a result, in this ...
Dependência entre perdas em risco operacional
(Universidade Federal de São Carlos, 2014-02-12)
In this work, we present and discuss the operational risk in the financial institutions, Basel Accord II, the structure of dependence between cumulative operational losses, a tool for modeling this dependence (theory of ...
Modelo de mistura com dependência Markoviana de primeira ordem
(Universidade Federal de São Carlos, 2014-09-12)
We present the mixture model with first order dependence, MMM(1). This model corresponds to a redefinition of the hidden Markov model (HMM) where a non observable variable is used to control the mixture. The usual mixture ...
