On the Relation between Prediction and Imputation Accuracy under Missing Covariates

no code implementations9 Dec 2021 Burim Ramosaj, Justus Tulowietzki, Markus Pauly

In this work, we analyze through simulation the interaction between imputation accuracy and prediction accuracy in regression learning problems with missing covariates when Machine Learning based methods for both, imputation and prediction are used.

Universal Approximation Theorems of Fully Connected Binarized Neural Networks

no code implementations4 Feb 2021 Mikail Yayla, Mario Günzel, Burim Ramosaj, Jian-Jia Chen

Neural networks (NNs) are known for their high predictive accuracy in complex learning problems.

Asymptotic Unbiasedness of the Permutation Importance Measure in Random Forest Models

no code implementations5 Dec 2019 Burim Ramosaj, Markus Pauly

Due to its intuitive idea and flexible usage, it is important to explore circumstances, for which the permutation importance based on Random Forest correctly indicates informative covariates.

Who wins the Miss Contest for Imputation Methods? Our Vote for Miss BooPF

1 code implementation30 Nov 2017 Burim Ramosaj, Markus Pauly

In this paper we study whether this approach can even be enhanced by other methods such as the stochastic gradient tree boosting method, the C5. 0 algorithm or modified random forest procedures.
