Fast and Efficient MMD-based Fair PCA via Optimization over Stiefel Manifold

2 code implementations23 Sep 2021 Junghyun Lee, Gwangsu Kim, Matt Olfat, Mark Hasegawa-Johnson, Chang D. Yoo

This paper defines fair principal component analysis (PCA) as minimizing the maximum mean discrepancy (MMD) between dimensionality-reduced conditional distributions of different protected classes.

Covariance-Robust Dynamic Watermarking

no code implementations31 Mar 2020 Matt Olfat, Stephen Sloan, Pedro Hespanhol, Matt Porter, Ram Vasudevan, Anil Aswani

Attack detection and mitigation strategies for cyberphysical systems (CPS) are an active area of research, and researchers have developed a variety of attack-detection tools such as dynamic watermarking.

Average Margin Regularization for Classifiers

no code implementations9 Oct 2018 Matt Olfat, Anil Aswani

We motivate this regularization by a novel generalization bound that shows a tradeoff in classifier accuracy between maximizing its margin and average margin.

Convex Formulations for Fair Principal Component Analysis

2 code implementations11 Feb 2018 Matt Olfat, Anil Aswani

We conclude by showing how our approach can be used to perform a fair (with respect to age) clustering of health data that may be used to set health insurance rates.

Spectral Algorithms for Computing Fair Support Vector Machines

no code implementations16 Oct 2017 Matt Olfat, Anil Aswani

Classifiers and rating scores are prone to implicitly codifying biases, which may be present in the training data, against protected classes (i. e., age, gender, or race).
