Log-concave density estimation in undirected graphical models

1 code implementation10 Jun 2022 Kaie Kubjas, Olga Kuznetsova, Elina Robeva, Pardis Semnani, Luca Sodomaco

We study the problem of maximum likelihood estimation of densities that are log-concave and lie in the graphical model corresponding to a given undirected graph $G$.

Ultra-marginal Feature Importance: Learning from Data with Causal Guarantees

1 code implementation21 Apr 2022 Joseph Janssen, Vincent Guan, Elina Robeva

Scientists frequently prioritize learning from data rather than training the best possible model; however, research in machine learning often prioritizes the latter.

Learning Linear Non-Gaussian Graphical Models with Multidirected Edges

no code implementations11 Oct 2020 Yiheng Liu, Elina Robeva, Huanqing Wang

In this paper we propose a new method to learn the underlying acyclic mixed graph of a linear non-Gaussian structural equation model given observational data.

Estimation of Monge Matrices

no code implementations5 Apr 2019 Jan-Christian Hütter, Cheng Mao, Philippe Rigollet, Elina Robeva

Monge matrices and their permuted versions known as pre-Monge matrices naturally appear in many domains across science and engineering.

Duality of Graphical Models and Tensor Networks

no code implementations4 Oct 2017 Elina Robeva, Anna Seigal

For example, marginalization in a graphical model is dual to contraction in the tensor network.
