Simulator-based explanation and debugging of hazard-triggering events in DNN-based safety-critical systems

1 code implementation1 Apr 2022 Hazem Fahmy, Fabrizio Pastore, Lionel Briand, Thomas Stifter

When Deep Neural Networks (DNNs) are used in safety-critical systems, engineers should determine the safety risks associated with failures (i. e., erroneous outputs) observed during testing.

Autoencoder for Synthetic to Real Generalization: From Simple to More Complex Scenes

1 code implementation1 Apr 2022 Steve Dias Da Cruz, Bertram Taetz, Thomas Stifter, Didier Stricker

Learning on synthetic data and transferring the resulting properties to their real counterparts is an important challenge for reducing costs and increasing safety in machine learning.

Autoencoder Attractors for Uncertainty Estimation

1 code implementation1 Apr 2022 Steve Dias Da Cruz, Bertram Taetz, Thomas Stifter, Didier Stricker

While input images close to known samples will converge to the same or similar attractor, input samples containing unknown features are unstable and converge to different training samples by potentially removing or changing characteristic features.

Illumination Normalization by Partially Impossible Encoder-Decoder Cost Function

no code implementations6 Nov 2020 Steve Dias Da Cruz, Bertram Taetz, Thomas Stifter, Didier Stricker

Our method exploits the availability of identical sceneries under different illumination and environmental conditions for which we formulate a partially impossible reconstruction target: the input image will not convey enough information to reconstruct the target in its entirety.

SVIRO: Synthetic Vehicle Interior Rear Seat Occupancy Dataset and Benchmark

1 code implementation10 Jan 2020 Steve Dias Da Cruz, Oliver Wasenmüller, Hans-Peter Beise, Thomas Stifter, Didier Stricker

We release SVIRO, a synthetic dataset for sceneries in the passenger compartment of ten different vehicles, in order to analyze machine learning-based approaches for their generalization capacities and reliability when trained on a limited number of variations (e. g. identical backgrounds and textures, few instances per class).
