Recovering Latent Confounders from High-dimensional Proxy Variables

1 code implementation21 Mar 2024 Nathan Mankovich, Homer Durand, Emiliano Diaz, Gherardo Varando, Gustau Camps-Valls

Detecting latent confounders from proxy variables is an essential problem in causal effect estimation.

Improving generalisation via anchor multivariate analysis

no code implementations4 Mar 2024 Homer Durand, Gherardo Varando, Nathan Mankovich, Gustau Camps-Valls

We introduce a causal regularisation extension to anchor regression (AR) for improved out-of-distribution (OOD) generalisation.

Causal hybrid modeling with double machine learning

no code implementations20 Feb 2024 Kai-Hendrik Cohrs, Gherardo Varando, Nuno Carvalhais, Markus Reichstein, Gustau Camps-Valls

Hybrid modeling integrates machine learning with scientific knowledge to enhance interpretability, generalization, and adherence to natural laws.

Discovering Causal Relations and Equations from Data

no code implementations21 May 2023 Gustau Camps-Valls, Andreas Gerhardus, Urmi Ninad, Gherardo Varando, Georg Martius, Emili Balaguer-Ballester, Ricardo Vinuesa, Emiliano Diaz, Laure Zanna, Jakob Runge

Discovering equations, laws and principles that are invariant, robust and causal explanations of the world has been fundamental in physical sciences throughout the centuries.

Learning and interpreting asymmetry-labeled DAGs: a case study on COVID-19 fear

no code implementations2 Jan 2023 Manuele Leonelli, Gherardo Varando

Bayesian networks are widely used to learn and reason about the dependence structure of discrete variables.

Highly Efficient Structural Learning of Sparse Staged Trees

no code implementations14 Jun 2022 Manuele Leonelli, Gherardo Varando

Several structural learning algorithms for staged tree models, an asymmetric extension of Bayesian networks, have been defined.

Structural Learning of Simple Staged Trees

no code implementations8 Mar 2022 Manuele Leonelli, Gherardo Varando

Bayesian networks faithfully represent the symmetric conditional independences existing between the components of a random vector.

Staged trees and asymmetry-labeled DAGs

no code implementations4 Aug 2021 Gherardo Varando, Federico Carli, Manuele Leonelli

Bayesian networks are a widely-used class of probabilistic graphical models capable of representing symmetric conditional independence between variables of interest using the topology of the underlying graph.

A new class of generative classifiers based on staged tree models

no code implementations26 Dec 2020 Federico Carli, Manuele Leonelli, Gherardo Varando

Generative models for classification use the joint probability distribution of the class variable and the features to construct a decision rule.

Learning DAGs without imposing acyclicity

2 code implementations4 Jun 2020 Gherardo Varando

We explore if it is possible to learn a directed acyclic graph (DAG) from data without imposing explicitly the acyclicity constraint.

Sparse Cholesky covariance parametrization for recovering latent structure in ordered data

no code implementations2 Jun 2020 Irene Córdoba, Concha Bielza, Pedro Larrañaga, Gherardo Varando

The sparse Cholesky parametrization of the inverse covariance matrix can be interpreted as a Gaussian Bayesian network; however its counterpart, the covariance Cholesky factor, has received, with few notable exceptions, little attention so far, despite having a natural interpretation as a hidden variable model for ordered signal data.

Graphical continuous Lyapunov models

2 code implementations21 May 2020 Gherardo Varando, Niels Richard Hansen

The linear Lyapunov equation of a covariance matrix parametrizes the equilibrium covariance matrix of a stochastic process.

The R Package stagedtrees for Structural Learning of Stratified Staged Trees

1 code implementation14 Apr 2020 Federico Carli, Manuele Leonelli, Eva Riccomagno, Gherardo Varando

stagedtrees is an R package which includes several algorithms for learning the structure of staged trees and chain event graphs from data.

Causal structure learning from time series: Large regression coefficients may predict causal links better in practice than small p-values

1 code implementation21 Feb 2020 Sebastian Weichwald, Martin E Jakobsen, Phillip B Mogensen, Lasse Petersen, Nikolaj Thams, Gherardo Varando

In this article, we describe the algorithms for causal structure learning from time series data that won the Causality 4 Climate competition at the Conference on Neural Information Processing Systems 2019 (NeurIPS).

Markov Property in Generative Classifiers

no code implementations12 Nov 2018 Gherardo Varando, Concha Bielza, Pedro Larrañaga, Eva Riccomagno

We show that, for generative classifiers, conditional independence corresponds to linear constraints for the induced discrimination functions.
