Evaluating machine learning models in non-standard settings: An overview and new findings

no code implementations23 Oct 2023 Roman Hornung, Malte Nalenz, Lennart Schneider, Andreas Bender, Ludwig Bothmann, Bernd Bischl, Thomas Augustin, Anne-Laure Boulesteix

Our findings corroborate the concern that standard resampling methods often yield biased GE estimates in non-standard settings, underscoring the importance of tailored GE estimation.

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.

Tree Ensembles with Rule Structured Horseshoe Regularization

no code implementations16 Feb 2017 Malte Nalenz, Mattias Villani

The aggressive noise shrinkage of our prior also makes it possible to complement the rules from boosting in Friedman and Popescu (2008) with an additional set of trees from random forest, which brings a desirable diversity to the ensemble.
