Approximating Counterfactual Bounds while Fusing Observational, Biased and Randomised Data Sources

no code implementations31 Jul 2023 Marco Zaffalon, Alessandro Antonucci, Rafael Cabañas, David Huber

We address the problem of integrating data from multiple, possibly biased, observational and interventional studies, to eventually compute counterfactuals in structural causal models.

Efficient Computation of Counterfactual Bounds

no code implementations17 Jul 2023 Marco Zaffalon, Alessandro Antonucci, Rafael Cabañas, David Huber, Dario Azzimonti

This allows us to compute exact counterfactual bounds via algorithms for credal nets on a subclass of structural causal models.

Bounding Counterfactuals under Selection Bias

1 code implementation26 Jul 2022 Marco Zaffalon, Alessandro Antonucci, Rafael Cabañas, David Huber, Dario Azzimonti

Causal analysis may be affected by selection bias, which is defined as the systematic exclusion of data from a certain subpopulation.

Diversity and Generalization in Neural Network Ensembles

1 code implementation26 Oct 2021 Luis A. Ortega, Rafael Cabañas, Andrés R. Masegosa

In this work, we combine and expand previously published results in a theoretically sound framework that describes the relationship between diversity and ensemble performance for a wide range of ensemble methods.

CREPO: An Open Repository to Benchmark Credal Network Algorithms

1 code implementation10 May 2021 Rafael Cabañas, Alessandro Antonucci

Credal networks are a popular class of imprecise probabilistic graphical models obtained as a Bayesian network generalization based on, so-called credal, sets of probability mass functions.

Causal Expectation-Maximisation

1 code implementation4 Nov 2020 Marco Zaffalon, Alessandro Antonucci, Rafael Cabañas

Structural causal models are the basic modelling unit in Pearl's causal theory; in principle they allow us to solve counterfactuals, which are at the top rung of the ladder of causation.

Structural Causal Models Are (Solvable by) Credal Networks

1 code implementation2 Aug 2020 Marco Zaffalon, Alessandro Antonucci, Rafael Cabañas

A structural causal model is made of endogenous (manifest) and exogenous (latent) variables.
