Structural Learning about Directed Acyclic Graphs from Multiple Databases

open access: yesAbstract and Applied Analysis, 2012
We propose an approach for structural learning of directed acyclic graphs from multiple databases. We first learn a local structure from each database separately, and then we combine these local structures together to construct a global graph over all ...

Dynamic Economic Relationships Among U.S. Soy Product Markets: Using a Cointegrated Vector Autoregression Approach with Directed Acyclic Graphs [PDF]

open access: yes
This paper applies a combined methodology of a recently developed directed acyclic graph (DAG) analysis with Johansen and Juselius' methods of the cointegrated vector autoregression (VAR) model to a monthly U.S.

Comparative analysis of course prerequisite networks for five Midwestern public institutions

open access: yesApplied Network Science
We present the first formal network analysis of curricular networks for public institutions, focusing around five midwestern universities. As a first such study of public institutions, our analyses are primarily macroscopic in nature, observing patterns ...

Induced Acyclic Tournaments in Random Digraphs: Sharp Concentration, Thresholds and Algorithms

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Given a simple directed graph D = (V,A), let the size of the largest induced acyclic tournament be denoted by mat(D). Let D ∈ D(n, p) (with p = p(n)) be a random instance, obtained by randomly orienting each edge of a random graph drawn from Ϟ(n, 2p). We

Classification of Fruits Using Computer Vision and a Multiclass Support Vector Machine

open access: yesSensors, 2012
Automatic classification of fruits via computer vision is still a complicated task due to the various properties of numerous types of fruits. We propose a novel classification method based on a multi-class kernel support vector machine (kSVM) with the ...
