Pseudocode No The paper does not contain any clearly labeled pseudocode or algorithm blocks.
Open Source Code No The paper does not provide an explicit statement or link for the open-source code of the described methodology.
Open Datasets Yes For the BLBF setting... for several multiclass classification datasets from the UCI repository (Asuncion & Newman, 2007). In the LTR setting... on the YAHOO! LTR Challenge corpus (set 1)...
Dataset Splits Yes For the LTR setting, we follow the experiment setup of Joachims et al. (2017) and conduct experiments on the YAHOO! LTR Challenge corpus (set 1), which comes with a train/validation/test split.
Hardware Specification No The paper does not provide specific details about the hardware used for running the experiments.
Software Dependencies No The paper does not provide specific software dependency details, such as library names with version numbers, needed to replicate the experiment.
Experiment Setup Yes For the BLBF learning experiments, we use POEM (Swaminathan & Joachims, 2015a) to learn stochastic linear policies. For LTR, Appendix C.2 derives a generalized version of propensity SVM-Rank (Joachims et al., 2017)... To avoid biases from the regression model, we adopt 90 percentile c IPS to conduct hyperparameter selection for M(or τ for SB) and regularization parameter on the partial feedback data simulated from the validation set. The experiments are run for 10 and 5 times on BLBF and LTR respectively and the average is reported. Details are shown in Appendix C.
