Abstract Interpretation-Based Feature Importance for SVMs

no code implementations22 Oct 2022 Abhinandan Pal, Francesco Ranzato, Caterina Urban, Marco Zanella

We leverage this abstraction in two ways: (1) to enhance the interpretability of SVMs by deriving a novel feature importance measure, called abstract feature importance (AFI), that does not depend in any way on a given dataset of the accuracy of the SVM and is very fast to compute, and (2) for verifying stability, notably individual fairness, of SVMs and producing concrete counterexamples when the verification fails.

Fair Training of Decision Tree Classifiers

no code implementations4 Jan 2021 Francesco Ranzato, Caterina Urban, Marco Zanella

We study the problem of formally verifying individual fairness of decision tree ensembles, as well as training tree models which maximize both accuracy and individual fairness.

Perfectly Parallel Fairness Certification of Neural Networks

1 code implementation5 Dec 2019 Caterina Urban, Maria Christakis, Valentin Wüstholz, Fuyuan Zhang

Recently, there is growing concern that machine-learning models, which currently assist or even automate decision making, reproduce, and in the worst case reinforce, bias of the training data.
