Research Type Experimental 6 Experiments We start with a simulated comparison of the oracle bounds and then present an empirical evaluation on real data. and Empirical evaluation on real datasets We studied the empirical performance of the bounds using standard random forest [Breiman, 2001] and a combination of heterogeneous classifiers on a subset of data sets from UCI and Lib SVM repositories [Dua and Graff, 2019, Chang and Lin, 2011].

Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code Yes The python source code for replicating the experiments is available at Github2. 2https://github.com/StephanLorenzen/MajorityVoteBounds
Open Datasets Yes We studied the empirical performance of the bounds using standard random forest [Breiman, 2001] and a combination of heterogeneous classifiers on a subset of data sets from UCI and Lib SVM repositories [Dua and Graff, 2019, Chang and Lin, 2011].
Dataset Splits Yes For each data set, we set aside 20% of the data for the test set Stest and used the remaining data S for ensemble construction, weight optimization and bound evaluation. and the empirical losses ˆL(h, S) in the bounds are replaced by the validation losses ˆL(h, Sh), and the sample size n is replaced by the minimal validation size minh |Sh|. and we generate these splits by bagging, where out-of-bag (OOB) samples Sh provide unbiased estimates of expected losses of individual hypotheses h.
Hardware Specification No No specific hardware details (like GPU/CPU models, memory) are provided for the experimental setup.
Software Dependencies No The paper mentions 'The python source code' but does not specify Python version or any library/solver names with their version numbers.
Experiment Setup Yes We take 100 fully grown trees, use the Gini criterion for splitting, and consider d features in each split.
