Learning ising and potts models with latent variables

S Goel - … Conference on Artificial Intelligence and Statistics, 2020 - proceedings.mlr.press
We study the problem of learning graphical models with latent variables. We give the {\em
first} efficient algorithms for learning: 1) ferromagnetic Ising models with latent variables …

[HTML][HTML] Pairwise sparse+ low-rank models for variables of mixed type

F Nussbaum, J Giesen - Journal of Multivariate Analysis, 2020 - Elsevier
Factor models have been proposed for a broad range of observed variables such as binary,
Gaussian, and variables of mixed types. They typically model a pairwise interaction …

Learning restricted boltzmann machines with arbitrary external fields

S Goel - arXiv preprint arXiv:1906.06595, 2019 - arxiv.org
We study the problem of learning graphical models with latent variables. We give the first
algorithm for learning locally consistent (ferromagnetic or antiferromagnetic) Restricted …

Learning exponential family graphical models with latent variables using regularized conditional likelihood

A Taeb, P Shah, V Chandrasekaran - arXiv preprint arXiv:2010.09386, 2020 - arxiv.org
Fitting a graphical model to a collection of random variables given sample observations is a
challenging task if the observed variables are influenced by latent variables, which can …

[HTML][HTML] Learning Gaussian graphical models with latent confounders

K Wang, A Franks, SY Oh - Journal of Multivariate Analysis, 2023 - Elsevier
Gaussian Graphical models (GGM) are widely used to estimate network structure in domains
ranging from biology to finance. In practice, data is often corrupted by latent confounders …

[PDF][PDF] Disentangling direct and indirect interactions in polytomous item response theory models

F Nussbaum, J Giesen - Proceedings of the Twenty-Ninth International …, 2021 - ijcai.org
Measurement is at the core of scientific discovery. However, some quantities, such as
economic behavior or intelligence, do not allow for direct measurement. They represent …

Interaction estimations in high-dimensional statistical models

L Tao - 2020 - wrap.warwick.ac.uk
High-dimensional statistics, which focus on datasets with a relatively large number of
variables compared to the sample size, have seen a dramatic surge of research interest and …

Generalised temporal network inference

V Tozzo - 2020 - tesidottorato.depositolegale.it
Network inference is becoming increasingly central in the analysis of complex phenomena
