Visual Transformers for Primates Classification and Covid Detection

no code implementations20 Dec 2022 Steffen Illium, Robert Müller, Andreas Sedlmeier, Claudia-Linnhoff Popien

We apply the vision transformer, a deep machine learning model build around the attention mechanism, on mel-spectrogram representations of raw audio recordings.

Capturing Dependencies within Machine Learning via a Formal Process Model

no code implementations10 Aug 2022 Fabian Ritz, Thomy Phan, Andreas Sedlmeier, Philipp Altmann, Jan Wieghardt, Reiner Schmid, Horst Sauer, Cornel Klein, Claudia Linnhoff-Popien, Thomas Gabor

We define a comprehensive SD process model for ML that encompasses most tasks and artifacts described in the literature in a consistent way.

Quantifying Multimodality in World Models

no code implementations14 Dec 2021 Andreas Sedlmeier, Michael Kölle, Robert Müller, Leo Baudrexel, Claudia Linnhoff-Popien

In this work, we analyze existing and propose new metrics for the detection and quantification of multimodal uncertainty in RL based World Models.

Policy Entropy for Out-of-Distribution Classification

no code implementations25 May 2020 Andreas Sedlmeier, Robert Müller, Steffen Illium, Claudia Linnhoff-Popien

One critical prerequisite for the deployment of reinforcement learning systems in the real world is the ability to reliably detect situations on which the agent was not trained.

Bayesian Surprise in Indoor Environments

no code implementations11 Apr 2020 Sebastian Feld, Andreas Sedlmeier, Markus Friedrich, Jan Franz, Lenz Belzner

Agents of LBS, such as mobile robots or non-player characters in computer games, may use the context surprise to focus more on important regions of a map for a better use or understanding of the floor plan.

Trajectory annotation using sequences of spatial perception

no code implementations11 Apr 2020 Sebastian Feld, Steffen Illium, Andreas Sedlmeier, Lenz Belzner

In the near future, more and more machines will perform tasks in the vicinity of human spaces or support them directly in their spatially bound activities.

Uncertainty-Based Out-of-Distribution Classification in Deep Reinforcement Learning

no code implementations31 Dec 2019 Andreas Sedlmeier, Thomas Gabor, Thomy Phan, Lenz Belzner, Claudia Linnhoff-Popien

We further present a first viable solution for calculating a dynamic classification threshold, based on the uncertainty distribution of the training data.

Uncertainty-Based Out-of-Distribution Detection in Deep Reinforcement Learning

no code implementations8 Jan 2019 Andreas Sedlmeier, Thomas Gabor, Thomy Phan, Lenz Belzner, Claudia Linnhoff-Popien

Although prior work has shown that dropout-based variational inference techniques and bootstrap-based approaches can be used to model epistemic uncertainty, the suitability for detecting OOD samples in deep reinforcement learning remains an open question.
