A Guide to Feature Importance Methods for Scientific Inference

1 code implementation19 Apr 2024 Fiona Katharina Ewald, Ludwig Bothmann, Marvin N. Wright, Bernd Bischl, Giuseppe Casalicchio, Gunnar König

Understanding the DGP requires insights into feature-target associations, which many ML models cannot directly provide, due to their opaque internal mechanisms.

Toward Understanding the Disagreement Problem in Neural Network Feature Attribution

1 code implementation17 Apr 2024 Niklas Koenen, Marvin N. Wright

In recent years, neural networks have demonstrated their remarkable ability to discern intricate patterns and relationships from raw data.

Interpretable Machine Learning for Survival Analysis

1 code implementation15 Mar 2024 Sophie Hanna Langbein, Mateusz Krzyziński, Mikołaj Spytek, Hubert Baniecki, Przemysław Biecek, Marvin N. Wright

With the spread and rapid advancement of black box machine learning models, the field of interpretable machine learning (IML) or explainable artificial intelligence (XAI) has become increasingly important over the last decade.

arfpy: A python package for density estimation and generative modeling with adversarial random forests

1 code implementation13 Nov 2023 Kristin Blesch, Marvin N. Wright

This paper introduces $\textit{arfpy}$, a python implementation of Adversarial Random Forests (ARF) (Watson et al., 2023), which is a lightweight procedure for synthesizing new data that resembles some given data.

survex: an R package for explaining machine learning survival models

1 code implementation30 Aug 2023 Mikołaj Spytek, Mateusz Krzyziński, Sophie Hanna Langbein, Hubert Baniecki, Marvin N. Wright, Przemysław Biecek

Due to their flexibility and superior performance, machine learning models frequently complement and outperform traditional statistical survival models.

Interpreting Deep Neural Networks with the Package innsight

1 code implementation19 Jun 2023 Niklas Koenen, Marvin N. Wright

The R package innsight offers a general toolbox for revealing variable-wise interpretations of deep neural networks' predictions with so-called feature attribution methods.

Conditional Feature Importance for Mixed Data

1 code implementation6 Oct 2022 Kristin Blesch, David S. Watson, Marvin N. Wright

The CPI enables conditional FI measurement that controls for any feature dependencies by sampling valid knockoffs - hence, generating synthetic data with similar statistical properties - for the data to be analyzed.

Unifying local and global model explanations by functional decomposition of low dimensional structures

2 code implementations12 Aug 2022 Munir Hiabu, Joseph T. Meyer, Marvin N. Wright

The interventional SHAP value of feature $k$ is a weighted sum of the main component and all interaction components that include $k$, with the weights given by the reciprocal of the component's dimension.

Testing Conditional Independence in Supervised Learning Algorithms

3 code implementations28 Jan 2019 David S. Watson, Marvin N. Wright

We propose the conditional predictive impact (CPI), a consistent and unbiased estimator of the association between one or several features and a given outcome, conditional on a reduced feature set.

Unbiased split variable selection for random survival forests using maximally selected rank statistics

no code implementations11 May 2016 Marvin N. Wright, Theresa Dankowski, Andreas Ziegler

However, instead of the conditional Monte-Carlo approach used in conditional inference forests, p-value approximations are employed.
