Manifold Restricted Interventional Shapley Values

1 code implementation10 Jan 2023 Muhammad Faaiz Taufiq, Patrick Blöbaum, Lenon Minorics

Shapley values are model-agnostic methods for explaining model predictions.

Unsupervised Model Selection for Time-series Anomaly Detection

1 code implementation3 Oct 2022 Mononito Goswami, Cristian Challu, Laurent Callot, Lenon Minorics, Andrey Kan

The practical problem of selecting the most accurate model for a given dataset without labels has received little attention in the literature.

Correcting Confounding via Random Selection of Background Variables

no code implementations4 Feb 2022 You-Lin Chen, Lenon Minorics, Dominik Janzing

We propose a method to distinguish causal influence from hidden confounding in the following scenario: given a target variable Y, potential causal drivers X, and a large number of background features, we propose a novel criterion for identifying causal relationship based on the stability of regression coefficients of X on Y with respect to selecting different background features.

Causal Forecasting:Generalization Bounds for Autoregressive Models

1 code implementation18 Nov 2021 Leena Chennuru Vankadara, Philipp Michael Faller, Michaela Hardt, Lenon Minorics, Debarghya Ghoshdastidar, Dominik Janzing

Under causal sufficiency, the problem of causal generalization amounts to learning under covariate shifts, albeit with additional structure (restriction to interventional distributions under the VAR model).

Quantifying intrinsic causal contributions via structure preserving interventions

no code implementations1 Jul 2020 Dominik Janzing, Patrick Blöbaum, Atalanti A. Mastakouri, Philipp M. Faller, Lenon Minorics, Kailash Budhathoki

We propose a notion of causal influence that describes the `intrinsic' part of the contribution of a node on a target node in a DAG.

Causal structure based root cause analysis of outliers

no code implementations5 Dec 2019 Dominik Janzing, Kailash Budhathoki, Lenon Minorics, Patrick Blöbaum

We describe a formal approach to identify 'root causes' of outliers observed in $n$ variables $X_1,\dots, X_n$ in a scenario where the causal relation between the variables is a known directed acyclic graph (DAG).

Feature relevance quantification in explainable AI: A causal problem

no code implementations29 Oct 2019 Dominik Janzing, Lenon Minorics, Patrick Blöbaum

We discuss promising recent contributions on quantifying feature relevance using Shapley values, where we observed some confusion on which probability distribution is the right one for dropped features.
