"A Rigorous Information-Theoretic Definition of Redundancy and Relevancy in Feature Selection Based on (Partial) Information Decomposition",
Journal of Machine Learning Research, vol. 24, no. 131, pp. 1-44, 2023.
Abstract
Selecting a minimal feature set that is maximally informative about a target variable is a central task in machine learning and statistics. Information theory provides a powerful framework for formulating feature selection algorithms---yet, a rigorous, information-theoretic definition of feature relevancy, which accounts for feature interactions such as redundant and synergistic contributions, is still missing. We argue that this lack is inherent...

"Adaptive Assistive Robotics: A Framework For Triadic Collaboration Between Humans and Robots",
Royal Society Open Science, 2023.
Abstract
Robots and other assistive technologies have a
huge potential to help society in domains ranging
from factory work to healthcare. However, safe
and eff ective control of robotic agents in these
environments is complex, especially when it involves
close interactions and multiple actors. We propose an
eff ective framework for optimising the behaviour of
robots and complementary assistive technologies in
systems comprising a mix of human and...

"Understanding the Uncertainty Loop of Human-Robot Interaction",
Workshop paper of CHI 23, 2023.
Abstract
Recently the field of Human-Robot Interaction gained popularity, due to the wide range of possibilities of how robots can support humans during daily tasks. One form of supportive robots are socially assistive robots which are specifically built for communicating with humans, e.g., as service robots or personal companions. As they understand humans through artificial intelligence, these robots will at some point make wrong assumptions about the h...

"Uncovering CWE-CVE-CPE Relations with Threat Knowledge Graphs",
arXiv, 2023.
Abstract
Security assessment relies on public information about products, vulnerabilities, and weaknesses. So far, databases in these categories have rarely been analyzed in combination. Yet, doing so could help predict unreported vulnerabilities and identify common threat patterns. In this paper, we propose a methodology for producing and optimizing a knowledge graph that aggregates knowledge from common threat databases (CVE, CWE, and CPE). We apply the...

"Gaze-based intention estimation: principles, methodologies, and applications in HRI",
arxiv, 2023.
Abstract
Intention prediction has become a relevant field of research in Human-Machine and Human-Robot Interaction. Indeed, any artificial
system (co)-operating with and along humans, designed to assist and coordinate its actions with a human partner, would benefit from
first inferring the human’s current intention. To spare the user the cognitive burden of explicitly uttering their goals, this inference
relies mostly on behavioral cues deemed indica...

"A Glimpse in ChatGPT Capabilities and its impact for AI research",
arXiv, 2023.
Abstract
Large language models (LLMs) have recently become a popular topic in the field of Artificial Intelligence (AI) research, with companies such as Google, Amazon, Facebook, and Apple (GAFA) investing heavily in their development. These models are trained on massive amounts of data and can be used for a wide range of tasks, including language translation, text generation, and question answering. However, the computational resources required to train ...

"Coordinated Adaptation of Reference Vectors and Scalarizing Functions in Evolutionary Many-objective Optimization",
IEEE Transactions on Systems, Man and Cybernetics: Systems, vol. 53, no. 2, pp. 763-775, 2023.
Abstract
It is highly desirable to adapt the reference vectors to unknown Pareto fronts in decomposition based evolutionary many-objective optimization. While adapting the reference vectors enhances the diversity of the achieved solutions, it often decelerates the convergence performance. To address this dilemma, we propose to adapt the reference vectors and the scalarizing functions in a coordinated way. On the one hand, the adaptation of the reference v...

"What Could a Social Mediator Robot Do? Lessons from Real-World Mediation Scenarios",
40th IEEE Conference on Robotics and Automation (ICRA 2023) Workshop: Towards a Balanced Cyberphysical Society: A Focus on Group Social Dynamics, 2023.
Abstract
The use of social robots as instruments for social mediation has been gaining traction in the field of Human-Robot Interaction (HRI).
The design of such robots and their behaviors is often driven by technological platforms and experimental set-ups which can be created in a laboratory.
To gain relevance for changing social relations of people in the real world however, it is also important to incorporate existing needs and implications of every...
