Structural Learning about Directed Acyclic Graphs from Multiple Databases

Abstract 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 ...

Constructing Structural VAR Models with Conditional Independence Graphs [PDF]

In this paper graphical modelling is used to select a sparse structure for a multivariate time series model of New Zealand interest rates. In particular, we consider a recursive structural vector autoregressions that can subsequently be described ...

Path Degeneracy and Applications

Journal of Graph Theory, EarlyView.
ABSTRACT In this work, we relate girth and path‐degeneracy in classes with sub‐exponential expansion, with explicit bounds for classes with polynomial expansion and proper minor‐closed classes that are tight up to a constant factor (and tight up to second order terms if a classical conjecture on existence of g $g$‐cages is verified). As an application,

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

Sensors, 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 ...

Saturated Partial Embeddings of Planar Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT In this work, we study how far one can deviate from optimal behavior when embedding a planar graph. For a planar graph G $G$, we say that a plane subgraph H ⊆ G $H\subseteq G$ is a plane‐saturated subgraph if adding any edge (possibly with new vertices) to H $H$ would either violate planarity or make the resulting graph no longer a subgraph of

Comparative analysis of course prerequisite networks for five Midwestern public institutions

Applied 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 ...

The association between sociodemographic and clinical factors and outcomes among inpatients with community‐acquired pneumonia

Journal of Hospital Medicine, EarlyView.
Abstract Background Community‐acquired pneumonia (CAP) is a leading cause of hospitalization and mortality. The influence of sociodemographic characteristics on adverse outcomes in adults hospitalized with CAP remains poorly understood, particularly for patients younger than 65.
