Simulating Lagrangian Subgrid‐Scale Dispersion on Neutral Surfaces in the Ocean

open access: yesJournal of Advances in Modeling Earth Systems, 2022
To capture the effects of mesoscale turbulent eddies, coarse‐resolution Eulerian ocean models resort to tracer diffusion parameterizations. Likewise, the effect of eddy dispersion needs to be parameterized when computing Lagrangian pathways using coarse ...

3D CLASSIFICATION OF CROSSROADS FROM MULTIPLE AERIAL IMAGES USING MARKOV RANDOM FIELDS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
The precise classification and reconstruction of crossroads from multiple aerial images is a challenging problem in remote sensing. We apply the Markov Random Fields (MRF) approach to this problem, a probabilistic model that can be used to consider ...

Outage Estimation in Electric Power Distribution Systems Using a Neural Network Ensemble

open access: yesEnergies, 2021
Outages in an overhead power distribution system are caused by multiple environmental factors, such as weather, trees, and animal activity. Since they form a major portion of the outages, the ability to accurately estimate these outages is a significant ...

Bayesian 2D Deconvolution: A Model for Diffuse Ultrasound Scattering [PDF]

open access: yesModeling, Identification and Control, 2001
Observed medical ultrasound images are degraded representations of the true acoustic tissue reflectance. The degradation is due to blur and speckle, and significantly reduces the diagnostic value of the images. In order to remove both blur and speckle we

Computing the Cramer-Rao bound of Markov random field parameters: Application to the Ising and the Potts models [PDF]

open access: yes, 2013
This report considers the problem of computing the Cramer-Rao bound for the parameters of a Markov random field. Computation of the exact bound is not feasible for most fields of interest because their likelihoods are intractable and have intractable ...

Collaborative filtering via sparse Markov random fields

open access: yes, 2016
Recommender systems play a central role in providing individualized access to information and services. This paper focuses on collaborative filtering, an approach that exploits the shared structure among mind-liked users and similar items. In particular,

Adaptive Gaussian Markov Random Fields with Applications in Human Brain Mapping [PDF]

open access: yes, 2005
Functional magnetic resonance imaging (fMRI) has become the standard technology in human brain mapping. Analyses of the massive spatio-temporal fMRI data sets often focus on parametric or nonparametric modeling of the temporal component, while spatial ...

High-Order Markov Random Fields and Their Applications in Cross-Language Speech Recognition

open access: yesCybernetics and Information Technologies, 2015
In this paper we study the cross-language speech emotion recognition using high-order Markov random fields, especially the application in Vietnamese speech emotion recognition.

Comparison of linear discriminant functions in image classification

open access: yesLietuvos Matematikos Rinkinys, 2010
In statistical image classification it is usually assumed that feature observations given labels are independently distributed. We have retracted this assumption by proposing stationary Gaussian random field (GRF) model for features observations ...
