Optimality of the quasi-score estimator in a mean-variance model with applications to measurement error models [PDF]
, 2006 We consider a regression of $y$ on $x$ given by a pair of mean and variance functions with a parameter vector $\theta$ to be estimated that also appears in the distribution of the regressor variable $x$. The estimation of $\theta$ is based on an extended

Keys to successful scientific VGI projects [PDF]
, 2016 Scientific projects are increasingly using volunteered geographic information (VGI) in order to collect and validate geographic data. This concept relies on the three challenges that first of all users can be found and second be convinced to collaborate and contribute and that scientists finally are able to gather high quality data for their projects ...

OSMDeepOD - Object Detection on Orthophotos with and for VGI [PDF]
GI_Forum, 2017 A great deal of the interesting information captured by aerial imagery is as yet unused, even though it could help to enrich maps and improve navigation. For this information to be made available, objects such as buildings or roads need to be recognized on images. This is laborious to do entirely manually, but non-trivial to perform computationally. In

BMEMat, EarlyView.The expertise‐inspired AI pipeline demonstrates significant clinical utility for rapid and precise analysis of dento‐maxillofafcial CBCT and benefits for intelligent oral health management. Abstract Owing to the tooth‐centered nature of most oral diseases, the tooth‐centric radial plane of cone‐beam computed tomography (CBCT) depicts the anatomical and

A characterization of Volunteered Geographic Information [PDF]
, 2010 This paper characterizes the Volunteered Geographic Information (VGI) phenomenon and explores comprehensively its relation with SDI. The SDI component view is used as common framework for describing the main characteristics of VGI and as framework for

Estimation of Laplacian spectra of direct and strong product graphs
, 2015 Calculating a product of multiple graphs has been studied in mathematics, engineering, computer science, and more recently in network science, particularly in the context of multilayer networks. One of the important questions to be addressed in this area
