Hossein Souri

I am a PhD student in Computer Science at Johns Hopkins University. I'm pleased to be advised by Dr. Rama Chellappa. I'm a Graduate Reseach Assistant at Artificial Intelligence for Engineering and Medicine Lab (AIEM).

Before joining JHU, I obtained my M.S. and B.S. in Electrical and Computer Engineering at University of Maryland, College Park and University of Tehran respectively. During my Masters studies I was a reseach assistant at University of Maryland Institute for Advanced Computer Studies(UMIACS).

I'm a machine learning and computer vision researcher working on various topics including adversarial attacks and defenses, GANs, face recognition, image restoration, segmentation, and activity detection.

GANs with Variational Entropy Regularizers: Applications in Mitigating the Mode-Collapse Issue
Pirazh Khorramshahi*, Hossein Souri*, Rama Chellappa, Soheil Feizi
arXiv, 2020
PDF / arXiv / bibtex

GANs often suffer from the mode collapse issue where the generator fails to capture all existing modes of the input distribution. 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. We call this approach GANs with Variational Entropy Regularizers (GAN+VER).

An adversarial learning algorithm for mitigating gender bias in face recognition

A novel approach called `Adversarial Gender De-biasing (AGD)' to reduce the strength of gender information in face recognition features.

ATFaceGAN: Single Face Image Restoration and Recognition from Atmospheric Turbulence
Chun Pong Lau, Hossein Souri, Rama Chellappa

PDF / arXiv / bibtex

In this work we propose a generative single frame restoration algorithm which disentangles the blur and deformation due to turbulence and reconstructs a restored image.
