Validity problems in clinical machine learning by indirect data labeling using consensus definitions

1 code implementation6 Nov 2023 Michael Hagmann, Shigehiko Schamoni, Stefan Riezler

We demonstrate a validity problem of machine learning in the vital application area of disease diagnosis in medicine.

Towards Inferential Reproducibility of Machine Learning Research

no code implementations8 Feb 2023 Michael Hagmann, Philipp Meier, Stefan Riezler

Instead of removing noise, we propose to incorporate several sources of variance, including their interaction with data properties, into an analysis of significance and reliability of machine learning evaluation, with the aim to draw inferences beyond particular instances of trained models.

Ensembling Neural Networks for Improved Prediction and Privacy in Early Diagnosis of Sepsis

1 code implementation1 Sep 2022 Shigehiko Schamoni, Michael Hagmann, Stefan Riezler

Ensembling neural networks is a long-standing technique for improving the generalization error of neural networks by combining networks with orthogonal properties via a committee decision.
