Graphical Local Genetic Algorithm for High-Dimensional Log-Linear Models

open access: yesMathematics, 2023
Graphical log-linear models are effective for representing complex structures that emerge from high-dimensional data. It is challenging to fit an appropriate model in the high-dimensional setting and many existing methods rely on a convenient class of ...

Interactive analysis of high-dimensional association structures with graphical models [PDF]

open access: yes, 1998
Graphical chain models are a capable tool for analyzing multivariate data. However, their practical use may still be cumbersome in some respect since fitting the model requires the application of an intensive selection strategy based on the calculation ...

Inferring Gene Dependency Networks from Genomic Longitudinal Data: a Functional Data Approach

open access: yesRevstat Statistical Journal, 2006
A key aim of systems biology is to unravel the regulatory interactions among genes and gene products in a cell. Here we investigate a graphical model that treats the observed gene expression over time as realizations of random curves.

Partition-Merge: Distributed Inference and Modularity Optimization

open access: yesIEEE Access, 2021
This paper presents a novel meta-algorithm, Partition-Merge (PM), which takes existing centralized algorithms for graph computation and makes them distributed and faster. In a nutshell, PM divides the graph into small subgraphs using our novel randomized

Neural Graphical Models

open access: yes, 2023
Probabilistic Graphical Models are often used to understand dynamics of a system. They can model relationships between features (nodes) and the underlying distribution. Theoretically these models can represent very complex dependency functions, but in practice often simplifying assumptions are made due to computational limitations associated with graph

Using a Gaussian Graphical Model to Explore Relationships Between Items and Variables in Environmental Psychology Research

open access: yesFrontiers in Psychology, 2019
Exploratory analyses are an important first step in psychological research, particularly in problem-based research where various variables are often included from multiple theoretical perspectives not studied together in combination before.
