Integrating Transformations in Probabilistic Circuits

no code implementations6 Oct 2023 Tom Schierenbeck, Vladimir Vutov, Thorsten Dickhaus, Michael Beetz

This study addresses the predictive limitation of probabilistic circuits and introduces transformations as a remedy to overcome it.

Towards a Neuronally Consistent Ontology for Robotic Agents

no code implementations26 Sep 2023 Florian Ahrens, Mihai Pomarlan, Daniel Beßler, Thorsten Fehr, Michael Beetz, Manfred Herrmann

It therefore employs a shared ontology to model the activity of both kinds of agents, empowering robots to learn from human experiences.

From Interactive to Co-Constructive Task Learning

no code implementations24 May 2023 Anna-Lisa Vollmer, Daniel Leidner, Michael Beetz, Britta Wrede

Humans have developed the capability to teach relevant aspects of new or adapted tasks to a social peer with very few task demonstrations by making use of scaffolding strategies that leverage prior knowledge and importantly prior joint experience to yield a joint understanding and a joint execution of the required steps to solve the task.

Joint Probability Trees

no code implementations14 Feb 2023 Daniel Nyga, Mareike Picklum, Tom Schierenbeck, Michael Beetz

We introduce Joint Probability Trees (JPT), a novel approach that makes learning of and reasoning about joint probability distributions tractable for practical applications.

Heuristic-free Optimization of Force-Controlled Robot Search Strategies in Stochastic Environments

Empirical Estimates on Hand Manipulation are Recoverable: A Step Towards Individualized and Explainable Robotic Support in Everyday Activities

no code implementations27 Jan 2022 Alexander Wich, Holger Schultheis, Michael Beetz

Specifically, we propose and explore the feasibility of structural causal models with non-parametric estimators to derive empirical estimates on hand behavior in the context of object manipulation in a virtual kitchen scenario.

Robot Program Parameter Inference via Differentiable Shadow Program Inversion

1 code implementation26 Mar 2021 Benjamin Alt, Darko Katic, Rainer Jäkel, Asil Kaan Bozcuoglu, Michael Beetz

Amortized Object and Scene Perception for Long-term Robot Manipulation

no code implementations28 Mar 2019 Ferenc Balint-Benczedi, Michael Beetz

Mobile robots, performing long-term manipulation activities in human environments, have to perceive a wide variety of objects possessing very different visual characteristics and need to reliably keep track of these throughout the execution of a task.
