Identifiability of latent-variable and structural-equation models: from linear to nonlinear

A Hyvärinen, I Khemakhem, R Monti - Annals of the Institute of Statistical …, 2024 - Springer
An old problem in multivariate statistics is that linear Gaussian models are often
unidentifiable. In factor analysis, an orthogonal rotation of the factors is unidentifiable, while …

Nonparametric identifiability of causal representations from unknown interventions

J von Kügelgen, M Besserve… - Advances in …, 2024 - proceedings.neurips.cc
We study causal representation learning, the task of inferring latent causal variables and
their causal relations from high-dimensional functions (“mixtures”) of the variables. Prior …

Effective Bayesian heteroscedastic regression with deep neural networks

A Immer, E Palumbo, A Marx… - Advances in Neural …, 2024 - proceedings.neurips.cc
Flexibly quantifying both irreducible aleatoric and model-dependent epistemic uncertainties
plays an important role for complex regression problems. While deep neural networks in …

Counterfactual identifiability of bijective causal models

A Nasr-Esfahany, M Alizadeh… - … Conference on Machine …, 2023 - proceedings.mlr.press
We study counterfactual identifiability in causal models with bijective generation
mechanisms (BGM), a class that generalizes several widely-used causal models in the …

Finding counterfactually optimal action sequences in continuous state spaces

S Tsirtsis, M Rodriguez - Advances in Neural Information …, 2024 - proceedings.neurips.cc
Whenever a clinician reflects on the efficacy of a sequence of treatment decisions for a
patient, they may try to identify critical time steps where, had they made different decisions …

Partial counterfactual identification of continuous outcomes with a curvature sensitivity model

V Melnychuk, D Frauen… - Advances in Neural …, 2023 - proceedings.neurips.cc
Counterfactual inference aims to answer retrospective" what if" questions and thus belongs
to the most fine-grained type of inference in Pearl's causality ladder. Existing methods for …

Scalable counterfactual distribution estimation in multivariate causal models

T Pham, S Shimizu, H Hino… - Causal Learning and …, 2024 - proceedings.mlr.press
We consider the problem of estimating the counterfactual joint distribution of multiple
quantities of interests (eg, outcomes) in a multivariate causal model extended from the …

Ocdaf: Ordered causal discovery with autoregressive flows

H Kamkari, V Zehtab, V Balazadeh… - arXiv preprint arXiv …, 2023 - arxiv.org
We propose OCDaf, a novel order-based method for learning causal graphs from
observational data. We establish the identifiability of causal graphs within multivariate …

Heteroscedastic Causal Structure Learning

B Duong, T Nguyen - ECAI 2023, 2023 - ebooks.iospress.nl
Heretofore, learning the directed acyclic graphs (DAGs) that encode the cause-effect
relationships embedded in observational data is a computationally challenging problem. A …

From Geometry to Causality-Ricci Curvature and the Reliability of Causal Inference on Networks

A Farzam, A Tannenbaum, G Sapiro - Forty-first International …, 2024 - openreview.net
Causal inference on networks faces challenges posed in part by violations of standard
identification assumptions due to dependencies between treatment units. Although graph …
