Limitations of Face Image Generation

1 code implementation13 Sep 2023 Harrison Rosenberg, Shimaa Ahmed, Guruprasad V Ramesh, Ramya Korlakai Vinayak, Kassem Fawaz

In particular, their ability to synthesize and modify human faces has spurred research into using generated face images in both training data augmentation and model performance assessments.

An Exploration of Multicalibration Uniform Convergence Bounds

no code implementations9 Feb 2022 Harrison Rosenberg, Robi Bhattacharjee, Kassem Fawaz, Somesh Jha

Given the prevalence of ERM sample complexity bounds, our proposed framework enables machine learning practitioners to easily understand the convergence behavior of multicalibration error for a myriad of classifier architectures.

Fairness Properties of Face Recognition and Obfuscation Systems

1 code implementation5 Aug 2021 Harrison Rosenberg, Brian Tang, Kassem Fawaz, Somesh Jha

We answer this question with an analytical and empirical exploration of recent face obfuscation systems.

Analyzing Accuracy Loss in Randomized Smoothing Defenses

no code implementations3 Mar 2020 Yue Gao, Harrison Rosenberg, Kassem Fawaz, Somesh Jha, Justin Hsu

In test-time attacks an adversary crafts adversarial examples, which are specially crafted perturbations imperceptible to humans which, when added to an input example, force a machine learning model to misclassify the given input example.

A Geometric Perspective on the Transferability of Adversarial Directions

no code implementations8 Nov 2018 Zachary Charles, Harrison Rosenberg, Dimitris Papailiopoulos

We show that these "transferable adversarial directions" are guaranteed to exist for linear separators of a given set, and will exist with high probability for linear classifiers trained on independent sets drawn from the same distribution.
