Independent Mechanism Analysis and the Manifold Hypothesis

no code implementations20 Dec 2023 Shubhangi Ghosh, Luigi Gresele, Julius von Kügelgen, Michel Besserve, Bernhard Schölkopf

As typical in ICA, previous work focused on the case with an equal number of latent components and observed mixtures.

CLadder: Assessing Causal Reasoning in Language Models

1 code implementation NeurIPS 2023 Zhijing Jin, Yuen Chen, Felix Leeb, Luigi Gresele, Ojasv Kamal, Zhiheng Lyu, Kevin Blin, Fernando Gonzalez Adauto, Max Kleiman-Weiner, Mrinmaya Sachan, Bernhard Schölkopf

Much of the existing work in natural language processing (NLP) focuses on evaluating commonsense causal reasoning in LLMs, thus failing to assess whether a model can perform causal inference in accordance with a set of well-defined formal rules.

Causal Component Analysis

1 code implementation NeurIPS 2023 Liang Wendong, Armin Kekić, Julius von Kügelgen, Simon Buchholz, Michel Besserve, Luigi Gresele, Bernhard Schölkopf

As a corollary, this interventional perspective also leads to new identifiability results for nonlinear ICA -- a special case of CauCA with an empty graph -- requiring strictly fewer datasets than previous results.

Probing the Robustness of Independent Mechanism Analysis for Representation Learning

no code implementations13 Jul 2022 Joanna Sliwa, Shubhangi Ghosh, Vincent Stimper, Luigi Gresele, Bernhard Schölkopf

One aim of representation learning is to recover the original latent code that generated the data, a task which requires additional information or inductive biases.

Learning explanations that are hard to vary

3 code implementations ICLR 2021 Giambattista Parascandolo, Alexander Neitz, Antonio Orvieto, Luigi Gresele, Bernhard Schölkopf

In this paper, we investigate the principle that `good explanations are hard to vary' in the context of deep learning.

Modeling Shared Responses in Neuroimaging Studies through MultiView ICA

1 code implementation NeurIPS 2020 Hugo Richard, Luigi Gresele, Aapo Hyvärinen, Bertrand Thirion, Alexandre Gramfort, Pierre Ablin

Group studies involving large cohorts of subjects are important to draw general conclusions about brain functional organization.

Simpson's paradox in Covid-19 case fatality rates: a mediation analysis of age-related causal effects

1 code implementation14 May 2020 Julius von Kügelgen, Luigi Gresele, Bernhard Schölkopf

We point out limitations and extensions for future work, and, finally, discuss the role of causal reasoning in the broader context of using AI to combat the Covid-19 pandemic.

Privacy-Preserving Causal Inference via Inverse Probability Weighting

no code implementations29 May 2019 Si Kai Lee, Luigi Gresele, Mijung Park, Krikamol Muandet

The use of inverse probability weighting (IPW) methods to estimate the causal effect of treatments from observational studies is widespread in econometrics, medicine and social sciences.

The Incomplete Rosetta Stone Problem: Identifiability Results for Multi-View Nonlinear ICA

no code implementations16 May 2019 Luigi Gresele, Paul K. Rubenstein, Arash Mehrjou, Francesco Locatello, Bernhard Schölkopf

In contrast to known identifiability results for nonlinear ICA, we prove that independent latent sources with arbitrary mixing can be recovered as long as multiple, sufficiently different noisy views are available.

Orthogonal Structure Search for Efficient Causal Discovery from Observational Data

no code implementations6 Mar 2019 Anant Raj, Luigi Gresele, Michel Besserve, Bernhard Schölkopf, Stefan Bauer

The problem of inferring the direct causal parents of a response variable among a large set of explanatory variables is of high practical importance in many disciplines.
