Self: Learning to filter noisy labels with self-ensembling

DT Nguyen, CK Mummadi, TPN Ngo…�- arXiv preprint arXiv�…, 2019 - arxiv.org
Deep neural networks (DNNs) have been shown to over-fit a dataset when being trained
with noisy labels for a long enough time. To overcome this problem, we present a simple and …

Universal adversarial perturbations against semantic image segmentation

…, M Chaithanya Kumar…�- Proceedings of the�…, 2017 - openaccess.thecvf.com
While deep learning is remarkably successful on perceptual tasks, it was also shown to be
vulnerable to adversarial perturbations of the input. These perturbations denote noise added …

Defending against universal perturbations with shared adversarial training

CK Mummadi, T Brox…�- Proceedings of the IEEE�…, 2019 - openaccess.thecvf.com
Classifiers such as deep neural networks have been shown to be vulnerable against
adversarial perturbations on problems with high-dimensional input space. While adversarial …

Test-time adaptation to distribution shift by confidence maximization and input transformation

CK Mummadi, R Hutmacher, K Rambach…�- arXiv preprint arXiv�…, 2021 - arxiv.org
Deep neural networks often exhibit poor performance on data that is unlikely under the train-time
data distribution, for instance data affected by corruptions. Previous works demonstrate …

Does enhanced shape bias improve neural network robustness to common corruptions?

CK Mummadi, R Subramaniam, R Hutmacher…�- arXiv preprint arXiv�…, 2021 - arxiv.org
Convolutional neural networks (CNNs) learn to extract representations of complex features,
such as object shapes and textures to solve image recognition tasks. Recent work indicates …

[HTML][HTML] Real-time and embedded detection of hand gestures with an IMU-based glove

CK Mummadi, F Philips Peter Leo, K Deep Verma…�- Informatics, 2018 - mdpi.com
This article focuses on the use of data gloves for human-computer interaction concepts,
where external sensors cannot always fully observe the user’s hand. A good concept hereby …

Deepusps: Deep robust unsupervised saliency prediction via self-supervision

T Nguyen, M Dax, CK Mummadi…�- Advances in�…, 2019 - proceedings.neurips.cc
Deep neural network (DNN) based salient object detection in images based on high-quality
labels is expensive. Alternative unsupervised approaches rely on careful selection of …

Adversarial examples for semantic image segmentation

V Fischer, MC Kumar, JH Metzen, T Brox�- arXiv preprint arXiv:1703.01101, 2017 - arxiv.org
Machine learning methods in general and Deep Neural Networks in particular have shown
to be vulnerable to adversarial perturbations. So far this phenomenon has mainly been …

Give me your attention: Dot-product attention considered harmful for adversarial patch robustness

…, N Finnie, M Munoz, CK Mummadi…�- Proceedings of the�…, 2022 - openaccess.thecvf.com
Neural architectures based on attention such as vision transformers are revolutionizing image
recognition. Their main benefit is that attention allows reasoning about all parts of a scene …

Real-time embedded recognition of sign language alphabet fingerspelling in an IMU-based glove

CK Mummadi, FPP Leo, KD Verma…�- Proceedings of the 4th�…, 2017 - dl.acm.org
