Exploiting the Layered Intrinsic Dimensionality of Deep Models for Practical Adversarial Training

no code implementations27 May 2024 Enes Altinisik, Safa Messaoud, Husrev Taha Sencar, Hassan Sajjad, Sanjay Chawla

Despite being a heavily researched topic, Adversarial Training (AT) is rarely, if ever, deployed in practical AI systems for two primary reasons: (i) the gained robustness is frequently accompanied by a drop in generalization and (ii) generating adversarial examples (AEs) is computationally prohibitively expensive.

A3T: Accuracy Aware Adversarial Training

no code implementations29 Nov 2022 Enes Altinisik, Safa Messaoud, Husrev Taha Sencar, Sanjay Chawla

Adversarial training has been empirically shown to be more prone to overfitting than standard training.

GREENER: Graph Neural Networks for News Media Profiling

no code implementations10 Nov 2022 Panayot Panayotov, Utsav Shukla, Husrev Taha Sencar, Mohamed Nabeel, Preslav Nakov

We study the problem of profiling news media on the Web with respect to their factuality of reporting and bias.

Impact of Adversarial Training on Robustness and Generalizability of Language Models

no code implementations10 Nov 2022 Enes Altinisik, Hassan Sajjad, Husrev Taha Sencar, Safa Messaoud, Sanjay Chawla

Specifically, we study the effect of pre-training data augmentation as well as training time input perturbations vs. embedding space perturbations on the robustness and generalization of transformer-based language models.

A Survey on Predicting the Factuality and the Bias of News Media

no code implementations16 Mar 2021 Preslav Nakov, Husrev Taha Sencar, Jisun An, Haewoon Kwak

The present level of proliferation of fake, biased, and propagandistic content online has made it impossible to fact-check every single suspicious claim or article, either manually or automatically.

PRNU Estimation from Encoded Videos Using Block-Based Weighting

2 code implementations18 Aug 2020 Enes Altinisik, Kasim Tasdemir, Husrev Taha Sencar

Estimating the photo-response non-uniformity (PRNU) of an imaging sensor from videos is a challenging task due to complications created by several processing steps in the camera imaging pipeline.
