Code for paper: “What Data Benefits My Classifier?” Enhancing Model Performance and Interpretability through Influence-Based Data Selection (ICLR 2024 ORAL)

Requirements

numpy
sklearn
pytorch
dtreeviz
pickle
matplotlib
argparse
modAL
typing

Section 4.1 (Toy Data)

• Please run python SEC-4-1.py and all experiments will run.

Section 4.2 (Algorithmic Performance)

• Please run python SEC-4-2.py and all experiments will run.
• Results will be stored as pickle files in the folder sec-4-2-outputs.
• Note that this also runs results for the MLP neural network which are actually presented in Appendix D.2 in the paper.

Section 5.1 (Distribution Shift - Fairness)

• Please run python SEC-5-1.py and all experiments for influence based trimming will run.
• Other baselines will be later added in a separate repository.

Section 5.2 (Fairness Poisoning Attacks)

• There are multiple datasets and attack types to choose: <choice> = nraa_attack_drug, nraa_attack_compas, nraa_attack_german, raa_attack_drug, raa_attack_compas, raa_attack_german
• Please run python SEC-5-2.py --dataset <choice> to run the experiments of your choice.

Section 5.3 (Adaptive Evasion Attacks)

• There are multiple datasets to choose from: <choice> = adult, bank, celeba, nlp
• Please run python SEC-5-3.py --dataset <choice> to run experiments on the dataset of your choice.

Section 5.4 (Online Learning)

• There are multiple datasets to choose from: <choice> = adult, bank, celeba, nlp
• Please run python SEC-5-4.py --dataset <choice> to run experiments on the dataset of your choice.

Section 5.5 (Active Learning)

• Please run python SEC-5-5.py and all experiments will run.
• Results will be stored as pickle files in the folder sec-5-5-outputs.

Appendix D.2 (EOP Results)

• Please run python APPENDIX-D.py and all experiments will run.
• Results will be stored as pickle files in the folder appendix-d-outputs.
• Note that these are the EOP results for both Logistic Regression and MLP, and the Appendix D.1 results are run as part of Section 4.2 experiments.

Appendix F (Visualizing Trees)

• Please run python APPENDIX-F.py <choice> where <choice> = adult, bank, celeba, nlp.
• Three trees will be generated for utility, fairness, and robustness.

Notes

• For fairness experiments, it is important to note that excessive trimming can actually lead to unfairness in the opposite direction. For keeping the code generic, we do not stop removing samples when fairness values (DP or EOP) start going below 0. However, for results, we consider all values below 0 to be 0 as it is trivial to put a threshold on the value. If you would like, it is easy to amend the code by stopping influence trimming when fairness value on the validation set < 0.
• Since the paper has multiple experiments, each has its own individual code files. There is no interdependence.
• Current datasets give desirable functionality with height reduced regular decision tree regressors. If you wish to use hierarchical shrinkage, please refer to the imodels python package, it is simple to replace the sklearn tree with these.
• The file acs_data_generator.py is custom code based on the folktables package and used to generate the distribution shift datasets-- it is provided here for reference.
