EML Online Speech Activity Detection for the Fearless Steps Challenge Phase-III

no code implementations21 Jun 2021 Omid Ghahabi, Volker Fischer

Speech Activity Detection (SAD), locating speech segments within an audio recording, is a main part of most speech technology applications.

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

no code implementations ICLR 2021 Chaithanya Kumar Mummadi, Ranjitha Subramaniam, Robin Hutmacher, Julien Vitay, Volker Fischer, Jan Hendrik Metzen

We conclude that the data augmentation caused by style-variation accounts for the improved corruption robustness and increased shape bias is only a byproduct.

SE(3)-Transformers: 3D Roto-Translation Equivariant Attention Networks

2 code implementations NeurIPS 2020 Fabian B. Fuchs, Daniel E. Worrall, Volker Fischer, Max Welling

We introduce the SE(3)-Transformer, a variant of the self-attention module for 3D point clouds and graphs, which is equivariant under continuous 3D roto-translations.

The streaming rollout of deep networks - towards fully model-parallel execution

1 code implementation NeurIPS 2018 Volker Fischer, Jan Köhler, Thomas Pfeil

Deep neural networks, and in particular recurrent networks, are promising candidates to control autonomous agents that interact in real-time with the physical world.

Statestream: A toolbox to explore layerwise-parallel deep neural networks

no code implementations ICLR 2018 Volker Fischer

Most artificial deep neural networks are partitioned into a directed graph of connected modules or layers and the layers themselves consist of elemental building blocks, such as single units.

Universal Adversarial Perturbations Against Semantic Image Segmentation

no code implementations ICCV 2017 Jan Hendrik Metzen, Mummadi Chaithanya Kumar, Thomas Brox, Volker Fischer

We show empirically that there exist barely perceptible universal noise patterns which result in nearly the same predicted segmentation for arbitrary inputs.

Adversarial Examples for Semantic Image Segmentation

no code implementations3 Mar 2017 Volker Fischer, Mummadi Chaithanya Kumar, Jan Hendrik Metzen, Thomas Brox

Machine learning methods in general and Deep Neural Networks in particular have shown to be vulnerable to adversarial perturbations.

On Detecting Adversarial Perturbations

1 code implementation14 Feb 2017 Jan Hendrik Metzen, Tim Genewein, Volker Fischer, Bastian Bischoff

In this work, we propose to augment deep neural networks with a small "detector" subnetwork which is trained on the binary classification task of distinguishing genuine data from data containing adversarial perturbations.
