Learning the distribution of latent variables in paired comparison models with round-robin scheduling

open access: yes, 2020
Paired comparison data considered in this paper originate from the comparison of a large number N of individuals in couples. The dataset is a collection of results of contests between two individuals when each of them has faced n opponents, where n is ...

Sparse Cholesky Covariance Parametrization for Recovering Latent Structure in Ordered Data

open access: yesIEEE Access, 2020
The sparse Cholesky parametrization of the inverse covariance matrix is directly related to Gaussian Bayesian networks. Its counterpart, the covariance Cholesky factorization model, has a natural interpretation as a hidden variable model for ordered ...

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.

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 ...
