Tsallis Entropy, Likelihood, and the Robust Seismic Inversion
Entropy, 2020 The nonextensive statistical mechanics proposed by Tsallis have been successfully used to model and analyze many complex phenomena. Here, we study the role of the generalized Tsallis statistics on the inverse problem theory.

Efficient Gaussian Sampling for Solving Large-Scale Inverse Problems using MCMC Methods [PDF]
, 2014 The resolution of many large-scale inverse problems using MCMC methods requires a step of drawing samples from a high dimensional Gaussian distribution.

International Journal of Mathematics and Mathematical Sciences, 2003 We give a new characterization of inverse Gaussian distributions using the regression of a suitable statistic based on a given random sample. A corollary of this result is a characterization of inverse Gaussian distribution based on a conditional joint ...

Mixtures of Shifted Asymmetric Laplace Distributions [PDF]
, 2012 A mixture of shifted asymmetric Laplace distributions is introduced and used for clustering and classification. A variant of the EM algorithm is developed for parameter estimation by exploiting the relationship with the general inverse Gaussian ...

The New Odd Log-Logistic Generalized Inverse Gaussian Regression Model
Journal of Probability and Statistics, 2019 We define a new four-parameter model called the odd log-logistic generalized inverse Gaussian distribution which extends the generalized inverse Gaussian and inverse Gaussian distributions. We obtain some structural properties of the new distribution. We

Elementary integrate-and-fire process underlies pulse amplitudes in Electrodermal activity.
PLoS Computational Biology, 2021 Electrodermal activity (EDA) is a direct read-out of sweat-induced changes in the skin's electrical conductance. Sympathetically-mediated pulsatile changes in skin sweat measured as EDA resemble an integrate-and-fire process, which yields an inverse ...

Higher order approximations to coal pyrolysis distribution
Journal of Sustainable Mining, 2018 Coal pyrolysis is a complex process involving a large number of chemical reactions. Pyrolysis is a key step in all coal conversion processes. The Distributed Activation Energy Model (DAEM) is a state-of-the art approach to the problem of predicting the ...

The density in the density of states method
, 2013 It has been suggested that for QCD at finite baryon density the distribution of the phase angle, i.e. the angle defined as the imaginary part of the logarithm of the fermion determinant, has a simple Gaussian form.

Structure estimation for discrete graphical models: Generalized covariance matrices and their inverses [PDF]
, 2013 We investigate the relationship between the structure of a discrete graphical model and the support of the inverse of a generalized covariance matrix. We show that for certain graph structures, the support of the inverse covariance matrix of indicator ...
