UQGAN: A Unified Model for Uncertainty Quantification of Deep Classifiers trained via Conditional GANs

1 code implementation31 Jan 2022 Philipp Oberdiek, Gernot A. Fink, Matthias Rottmann

We present an approach to quantifying both aleatoric and epistemic uncertainty for deep neural networks in image classification, based on generative adversarial networks (GANs).

Detection and Retrieval of Out-of-Distribution Objects in Semantic Segmentation

1 code implementation14 May 2020 Philipp Oberdiek, Matthias Rottmann, Gernot A. Fink

When deploying deep learning technology in self-driving cars, deep neural networks are constantly exposed to domain shifts.

Exploring Confidence Measures for Word Spotting in Heterogeneous Datasets

no code implementations26 Mar 2019 Fabian Wolf, Philipp Oberdiek, Gernot A. Fink

In recent years, convolutional neural networks (CNNs) took over the field of document analysis and they became the predominant model for word spotting.

Attribute Retrieval

Classification Uncertainty of Deep Neural Networks Based on Gradient Information

no code implementations22 May 2018 Philipp Oberdiek, Matthias Rottmann, Hanno Gottschalk

If we however allow the meta classifier to be trained on uncertainty metrics for some out-of-distribution samples, meta classification for concepts remote from EMNIST digits (then termed known unknowns) can be improved considerably.
