DISBELIEVE: Distance Between Client Models is Very Essential for Effective Local Model Poisoning Attacks

no code implementations14 Aug 2023 Indu Joshi, Priyank Upadhya, Gaurav Kumar Nayak, Peter Schüffler, Nassir Navab

Leveraging this, we introduce DISBELIEVE, a local model poisoning attack that creates malicious parameters or gradients such that their distance to benign clients' parameters or gradients is low respectively but at the same time their adverse effect on the global model's performance is high.

Improved Techniques for the Conditional Generative Augmentation of Clinical Audio Data

no code implementations5 Nov 2022 Mane Margaryan, Matthias Seibold, Indu Joshi, Mazda Farshad, Philipp Fürnstahl, Nassir Navab

In contrast to previously proposed fully convolutional models, the proposed model implements residual Squeeze and Excitation modules in the generator architecture.

DILF-EN framework for Class-Incremental Learning

no code implementations23 Dec 2021 Mohammed Asad Karim, Indu Joshi, Pratik Mazumder, Pravendra Singh

We apply our proposed approach to state-of-the-art class-incremental learning methods and empirically show that our framework significantly improves the performance of these methods.

Sensor-invariant Fingerprint ROI Segmentation Using Recurrent Adversarial Learning

no code implementations3 Jul 2021 Indu Joshi, Ayush Utkarsh, Riya Kothari, Vinod K Kurmi, Antitza Dantcheva, Sumantra Dutta Roy, Prem Kumar Kalra

In order to save the human effort in generating annotations required by state-of-the-art, we propose a fingerprint roi segmentation model which aligns the features of fingerprint images derived from the unseen sensor such that they are similar to the ones obtained from the fingerprints whose ground truth roi masks are available for training.
