FashionFail: Addressing Failure Cases in Fashion Object Detection and Segmentation

no code implementations12 Apr 2024 Riza Velioglu, Robin Chan, Barbara Hammer

In the realm of fashion object detection and segmentation for online shopping images, existing state-of-the-art fashion parsing models encounter limitations, particularly when exposed to non-model-worn apparel and close-up shots.

Have We Ever Encountered This Before? Retrieving Out-of-Distribution Road Obstacles from Driving Scenes

no code implementations8 Sep 2023 Youssef Shoeb, Robin Chan, Gesina Schwalbe, Azarm Nowzard, Fatma Güney, Hanno Gottschalk

In this work, we extend beyond identifying OoD road obstacles in video streams and offer a comprehensive approach to extract sequences of OoD road obstacles using text queries, thereby proposing a way of curating a collection of OoD data for subsequent analysis.

Which Spurious Correlations Impact Reasoning in NLI Models? A Visual Interactive Diagnosis through Data-Constrained Counterfactuals

no code implementations21 Jun 2023 Robin Chan, Afra Amini, Mennatallah El-Assady

We present a human-in-the-loop dashboard tailored to diagnosing potential spurious features that NLI models rely on for predictions.

LU-Net: Invertible Neural Networks Based on Matrix Factorization

1 code implementation21 Feb 2023 Robin Chan, Sarina Penquitt, Hanno Gottschalk

Also, the computation of the determinant of the Jacobian matrix of such layers is cheap.

Two Video Data Sets for Tracking and Retrieval of Out of Distribution Objects

1 code implementation5 Oct 2022 Kira Maag, Robin Chan, Svenja Uhlemeyer, Kamil Kowol, Hanno Gottschalk

We present the SOS data set containing 20 video sequences of street scenes and more than 1000 labeled frames with up to two OOD objects.

What should AI see? Using the Public's Opinion to Determine the Perception of an AI

no code implementations9 Jun 2022 Robin Chan, Radin Dardashti, Meike Osinski, Matthias Rottmann, Dominik Brüggemann, Cilia Rücker, Peter Schlicht, Fabian Hüger, Nikol Rummel, Hanno Gottschalk

Finally, we include comments from industry leaders in the field of AI safety on the applicability of survey based elements in the design of AI functionalities in automated driving.

Detecting and Learning the Unknown in Semantic Segmentation

no code implementations17 Feb 2022 Robin Chan, Svenja Uhlemeyer, Matthias Rottmann, Hanno Gottschalk

However, this is in contrast to the open world assumption in automated driving that DNNs are deployed to.

SegmentMeIfYouCan: A Benchmark for Anomaly Segmentation

2 code implementations30 Apr 2021 Robin Chan, Krzysztof Lis, Svenja Uhlemeyer, Hermann Blum, Sina Honari, Roland Siegwart, Pascal Fua, Mathieu Salzmann, Matthias Rottmann

State-of-the-art semantic or instance segmentation deep neural networks (DNNs) are usually trained on a closed set of semantic classes.

Entropy Maximization and Meta Classification for Out-Of-Distribution Detection in Semantic Segmentation

1 code implementation ICCV 2021 Robin Chan, Matthias Rottmann, Hanno Gottschalk

In our experiments we consistently observe a clear additional gain in OoD detection performance, cutting down the number of detection errors by up to 52% when comparing the best baseline with our results.

MetaFusion: Controlled False-Negative Reduction of Minority Classes in Semantic Segmentation

no code implementations16 Dec 2019 Robin Chan, Matthias Rottmann, Fabian Hüger, Peter Schlicht, Hanno Gottschalk

We present proof-of-concept results for CIFAR-10, and prove the efficiency of our method for the semantic segmentation of street scenes on the Cityscapes dataset based on predicted instances of the 'human' class.

The Ethical Dilemma when (not) Setting up Cost-based Decision Rules in Semantic Segmentation

no code implementations2 Jul 2019 Robin Chan, Matthias Rottmann, Radin Dardashti, Fabian Hüger, Peter Schlicht, Hanno Gottschalk

Neural networks for semantic segmentation can be seen as statistical models that provide for each pixel of one image a probability distribution on predefined classes.

Application of Decision Rules for Handling Class Imbalance in Semantic Segmentation

1 code implementation24 Jan 2019 Robin Chan, Matthias Rottmann, Fabian Hüger, Peter Schlicht, Hanno Gottschalk

We approach such potential misclassifications by weighting the posterior class probabilities with the prior class probabilities which in our case are the inverse frequencies of the corresponding classes in the training dataset.
