A Deep Dive into Dataset Imbalance and Bias in Face Identification

no code implementations15 Mar 2022 Valeriia Cherepanova, Steven Reich, Samuel Dooley, Hossein Souri, Micah Goldblum, Tom Goldstein

This is an unfortunate omission, as 'imbalance' is a more complex matter in identification; imbalance may arise in not only the training data, but also the testing data, and furthermore may affect the proportion of identities belonging to each demographic group or the number of images belonging to each identity.

Identification of Attack-Specific Signatures in Adversarial Examples

no code implementations13 Oct 2021 Hossein Souri, Pirazh Khorramshahi, Chun Pong Lau, Micah Goldblum, Rama Chellappa

The adversarial attack literature contains a myriad of algorithms for crafting perturbations which yield pathological behavior in neural networks.

Sleeper Agent: Scalable Hidden Trigger Backdoors for Neural Networks Trained from Scratch

1 code implementation16 Jun 2021 Hossein Souri, Liam Fowl, Rama Chellappa, Micah Goldblum, Tom Goldstein

In contrast, the Hidden Trigger Backdoor Attack achieves poisoning without placing a trigger into the training data at all.

Certified Watermarks for Neural Networks

no code implementations1 Jan 2021 Arpit Amit Bansal, Ping-Yeh Chiang, Michael Curry, Hossein Souri, Rama Chellappa, John P Dickerson, Rajiv Jain, Tom Goldstein

Watermarking is a commonly used strategy to protect creators' rights to digital images, videos and audio.

GANs with Variational Entropy Regularizers: Applications in Mitigating the Mode-Collapse Issue

no code implementations24 Sep 2020 Pirazh Khorramshahi, Hossein Souri, Rama Chellappa, Soheil Feizi

To tackle this issue, we take an information-theoretic approach and maximize a variational lower bound on the entropy of the generated samples to increase their diversity.

Towards Gender-Neutral Face Descriptors for Mitigating Bias in Face Recognition

no code implementations14 Jun 2020 Prithviraj Dhar, Joshua Gleason, Hossein Souri, Carlos D. Castillo, Rama Chellappa

Therefore, we present a novel `Adversarial Gender De-biasing algorithm (AGENDA)' to reduce the gender information present in face descriptors obtained from previously trained face recognition networks.

ATFaceGAN: Single Face Image Restoration and Recognition from Atmospheric Turbulence

no code implementations7 Oct 2019 Chun Pong Lau, Hossein Souri, Rama Chellappa

To mitigate the degradation due to turbulence which includes deformation and blur, we propose a generative single frame restoration algorithm which disentangles the blur and deformation due to turbulence and reconstructs a restored image.
