Comparing Machine Learning Algorithms by Union-Free Generic Depth

1 code implementation20 Dec 2023 Hannah Blocher, Georg Schollmeyer, Malte Nalenz, Christoph Jansen

We propose a framework for descriptively analyzing sets of partial orders based on the concept of depth functions.

Robust Statistical Comparison of Random Variables with Locally Varying Scale of Measurement

1 code implementation22 Jun 2023 Christoph Jansen, Georg Schollmeyer, Hannah Blocher, Julian Rodemann, Thomas Augustin

Spaces with locally varying scale of measurement, like multidimensional structures with differently scaled dimensions, are pretty common in statistics and machine learning.

In all LikelihoodS: How to Reliably Select Pseudo-Labeled Data for Self-Training in Semi-Supervised Learning

1 code implementation2 Mar 2023 Julian Rodemann, Christoph Jansen, Georg Schollmeyer, Thomas Augustin

As a practical proof of concept, we spotlight the application of three of our robust extensions on simulated and real-world data.

Multi-Target Decision Making under Conditions of Severe Uncertainty

no code implementations13 Dec 2022 Christoph Jansen, Georg Schollmeyer, Thomas Augustin

The quality of consequences in a decision making problem under (severe) uncertainty must often be compared among different targets (goals, objectives) simultaneously.

Statistical Comparisons of Classifiers by Generalized Stochastic Dominance

no code implementations5 Sep 2022 Christoph Jansen, Malte Nalenz, Georg Schollmeyer, Thomas Augustin

This yields indeed a powerful framework for the statistical comparison of classifiers over multiple data sets with respect to multiple quality criteria simultaneously.

Information efficient learning of complexly structured preferences: Elicitation procedures and their application to decision making under uncertainty

no code implementations19 Oct 2021 Christoph Jansen, Hannah Blocher, Thomas Augustin, Georg Schollmeyer

The first approach directly utilizes the collected ranking data for obtaining the ordinal part of the preferences, while their cardinal part is constructed implicitly by measuring meta data on the decision maker's consideration times.
