Pseudocode No The paper describes methods and theoretical findings but does not include any clearly labeled pseudocode or algorithm blocks.
Open Source Code Yes code available at https://github.com/osu-srml/Unforeseeable-SC/tree/main
Open Datasets Yes We conduct experiments on both synthetic Gaussian data and FICO score data (Hardt et al., 2016b).
Dataset Splits No The paper mentions using FICO data and synthetic Gaussian data, and describes some preprocessing (normalization, estimating distributions) but does not provide specific training/test/validation splits for any dataset.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory) used for running its experiments.
Software Dependencies No The paper does not provide specific software dependencies or library versions used in the experiments.
Experiment Setup Yes We use the preprocessed dataset containing the CDF of scores FX|S(x|s), qualification likelihoods PY |XS(1|x, s), and qualification rates αs for four racial groups (Caucasian, African American, Hispanic, Asian). All scores are normalized to [0, 1]. Similar to Zhang et al. (2022), we use these to estimate the conditional feature distributions PX|Y S(x|y, s) using beta distribution Beta(ays, bys). The results are shown in Fig. 9. We assume the improved feature distribution P I(x) Beta a1s+a0s 2 , b1s+b0s 2 and CM CI N(0, 0.25) for all groups, under which Assumption 2.2 and 2.1 are satisfied (see Fig. 8). We also considered other feature/cost distributions and observed similar results. Note that for each group s, the decision-maker finds its own optimal threshold θ s or θ s(ki) or bθ s by maximizing the utility associated with that group, i.e., maxθs E[R(D, Y )|S = s].
