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.

Conditional Random Field-Guided Multi-Focus Image Fusion

open access: yesJournal of Imaging, 2022
Multi-Focus image fusion is of great importance in order to cope with the limited Depth-of-Field of optical lenses. Since input images contain noise, multi-focus image fusion methods that support denoising are important.

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 ...
