Iteratively regularized Newton-type methods for general data misfit functionals and applications to Poisson data [PDF]
, 2012 We study Newton type methods for inverse problems described by nonlinear operator equations $F(u)=g$ in Banach spaces where the Newton equations $F'(u_n;u_{n+1}-u_n) = g-F(u_n)$ are regularized variationally using a general data misfit functional and a ...

A Software Development Model for the Automatic Generation of Classes
CLEI Electronic Journal, 2018 In this paper it is presented a software development model based on transformations that allows to derive, in an automatic way, classes in object-oriented programming languages (Ada 95, C++, Eiffel and Java) starting from formal specifications.

Bayesian nonparametric models for spatially indexed data of mixed type [PDF]
, 2014 We develop Bayesian nonparametric models for spatially indexed data of mixed type. Our work is motivated by challenges that occur in environmental epidemiology, where the usual presence of several confounding variables that exhibit complex interactions ...

Model Error Correction in Data Assimilation by Integrating Neural Networks
Big Data Mining and Analytics, 2019 In this paper, we suggest a new methodology which combines Neural Networks (NN) into Data Assimilation (DA). Focusing on the structural model uncertainty, we propose a framework for integration NN with the physical models by DA algorithms, to improve ...

Chain graph models of multivariate regression type for categorical data [PDF]
, 2011 We discuss a class of chain graph models for categorical variables defined by what we call a multivariate regression chain graph Markov property. First, the set of local independencies of these models is shown to be Markov equivalent to those of a chain ...

MissForest - nonparametric missing value imputation for mixed-type data
, 2011 Modern data acquisition based on high-throughput technology is often facing the problem of missing data. Algorithms commonly used in the analysis of such large-scale data often depend on a complete set.
