The Illusion of Competence: Evaluating the Effect of Explanations on Users' Mental Models of Visual Question Answering Systems

1 code implementation27 Jun 2024 Judith Sieker, Simeon Junker, Ronja Utescher, Nazia Attari, Heiko Wersing, Hendrik Buschmeier, Sina Zarrieß

We examine how users perceive the limitations of an AI system when it encounters a task that it cannot perform perfectly and whether providing explanations alongside its answers aids users in constructing an appropriate mental model of the system's capabilities and limitations.

To Help or Not to Help: LLM-based Attentive Support for Human-Robot Group Interactions

no code implementations19 Mar 2024 Daniel Tanneberg, Felix Ocker, Stephan Hasler, Joerg Deigmoeller, Anna Belardinelli, Chao Wang, Heiko Wersing, Bernhard Sendhoff, Michael Gienger

In addition to following user instructions, Attentive Support is capable of deciding when and how to support the humans, and when to remain silent to not disturb the group.

Addressing Data Scarcity in Multimodal User State Recognition by Combining Semi-Supervised and Supervised Learning

no code implementations8 Feb 2022 Hendric Voß, Heiko Wersing, Stefan Kopp

Detecting mental states of human users is crucial for the development of cooperative and intelligent robots, as it enables the robot to understand the user's intentions and desires.

Intuitiveness in Active Teaching

no code implementations25 Dec 2020 Jan Philip Göpfert, Ulrike Kuhl, Lukas Hindemith, Heiko Wersing, Barbara Hammer

After developing a theoretical framework of intuitiveness as a property of algorithms, we introduce an active teaching paradigm involving a prototypical two-dimensional spatial learning task as a method to judge the efficacy of human-machine interactions.

Interpretable Locally Adaptive Nearest Neighbors

no code implementations8 Nov 2020 Jan Philip Göpfert, Heiko Wersing, Barbara Hammer

When training automated systems, it has been shown to be beneficial to adapt the representation of data by learning a problem-specific metric.

Recovering Localized Adversarial Attacks

no code implementations21 Oct 2019 Jan Philip Göpfert, Heiko Wersing, Barbara Hammer

In this contribution, we focus on the capabilities of explainers for convolutional deep neural networks in an extreme situation: a setting in which humans and networks fundamentally disagree.

Adversarial attacks hidden in plain sight

1 code implementation25 Feb 2019 Jan Philip Göpfert, André Artelt, Heiko Wersing, Barbara Hammer

Convolutional neural networks have been used to achieve a string of successes during recent years, but their lack of interpretability remains a serious issue.

Optimum Reject Options for Prototype-based Classification

no code implementations23 Mar 2015 Lydia Fischer, Barbara Hammer, Heiko Wersing

We analyse optimum reject strategies for prototype-based classifiers and real-valued rejection measures, using the distance of a data point to the closest prototype or probabilistic counterparts.
