Congratulations to (now Dr.) Jannis Walk, who has successfully defended his PhD thesis on “Image-based Decision Support Systems: Technical Concepts, Design Knowledge, and Applications for Sustainability” at KIT.

 
Mining large sets of image data can provide valuable insights that support decisions and form the basis of novel services. In his work, Jannis develops and applies AI-based segmantic segmentation for decision support – in three steps:

1. Technical concepts that are required to realize such systems: So, quantifying the uncertainty of AI-based segmantic segmentation helps to identify needs for human support (via additional labelling or via making decisions).

2. Design knowledge: General design principles for such decision support systems are developed and successfully evaluated in real-world settings.

3. Applications for sustainability: It is illustrated how image-based decision support systems enable novel services to reduce ecological footprints of production.

 
A big thank you goes to the KIT examination committee (including Michael Färber, Frank Schultmann and Andreas Geyer-Schulz) as well as to Plansee Group / CERATIZIT in Reutte/Austria having served as a strong and reliable partner in providing inspiration, data, and evaluation options for the work.

Our research group successfully authored and presented two papers at the AAAI '23 conference, held in Washington, DC. AAAI is the premier conference on research on the advancement of artificial intelligence.

In a first paper, Patrick Hemmer et al. propose a solution to a major limitation of "learning to defer" algorithms, which require a large number of human expert predictions to learn whether an AI system should make a prediction itself or defer the decision to a human expert.

Our second paper, led by Jakob Schoeffer et al., in joint collaboration with international scholars from the MD4SG initiative, proposes and analyses the "fair exposure problem", which occurs when online platforms are required to address their users with equal shares of preferred and non-preferred content.

Since October 1, 2022, KSRI participates in the new, by the BMBF publicly funded project ZirkulEA. The project was kicked off last Wednesday and Thursday, November 30 to December 1, 2022, with about 30 consortial partners meeting locally in Karlsruhe. The aim of the research project is to design a circular value chain that is as economical as possible with the aid of a comprehensive cross-company exchange of information. This goal is to be illustrated in three exemplary use cases in order to ensure a timely realization of the developed concepts in industrial practice.

As part of the ZirkulEA project, we collaborate with three research institutes and six industry partners to develop research results and practical solutions for a circular economy of the automotive electric powertrain through intelligent disassembly and traceability. Particularly, we focus on the identification and derivation of the necessary information requirements. Suitable technical solutions for data acquisition and data dissemination, as well as software and hardware, will be selected. In addition, an overall concept for data exchange in the form of a partner ecosystem will be developed (including business models and incentive systems for participation).

If you have any questions about the project, please feel free to contact our colleagues Carina Benz, Marcel Fassnacht, Daniel Heinz or .

On October 14, we had the great honour of inviting to the 8th Karlsruhe Service Summit. The day's theme was "Services and AI for Sustainability", and we were happy to welcome more than 70 participants from research and industry.

An interdisciplinary team from the DSI research group at KIT and Aalto Online Learning at Aalto University (Finland) collaborated on a research project about online learning. In particular, the project aimed at providing educators guidance in creating online learning courses. Therefore, the team consisting of Lea Blecher (Master’s student @KIT), Tomi Kauppinen (head of Aalto Online Learning), and Lara Riefle (researcher @KIT) used a design science research approach and developed and evaluated a digital toolbox that interactively presents best practices and implementation guidelines for online learning practices.

Today, the resulting toolbox is integrated into Aalto’s teaching resources and helps educators create high-quality online courses.

This year’s student projects as part of the course on Artificial Intelligence in Service Systems - Applications in Computer Vision ended with various exciting presentations from the student teams on July, 31st. The topics ranged from computer vision-aided improvements in recycling over detecting diseases in wine yards to preserving privacy in video streams.

In the course, we teach the theoretical foundations of selected machine learning algorithms (e.g., convolutional neural networks) and development concepts (e.g., developing modeling, training, inference pipelines) and teach how to apply these concepts to build a functioning prototype of an analytics-based service (e.g., inference running on a device). During the course, students work in small groups to apply the learned concepts in the programming language Python using packages such as Keras, Tensorflow or Scikit-Learn. For more information on the course and this year’s students’ projects, please visit https://www.aiss-cv.com.

Special thanks to lecturer Björn Schmitz and the teaching team including Philipp Spitzer and Johannes Jakubik. Looking forward to the course next year!

Just recently, we hosted the final presentations of the practical seminar "Data Science for the Industrial Internet of Things" at KIT. For the fifth year now already the seminar is organized with our cooperation partner Trelleborg.

We had the pleasure to welcome our partners from Trelleborg, who provided four interesting real-world use-cases from domains like Engineering, Manufacturing and Sales. Students from the field of industrial engineering, business informatics and computer science applied their skills from data science and applied machine learning on those datasets to develop prototypes that generate great insights and help improve business processes.

Special thanks to Professor Satzger and Alexander Jarosch, Michael Fryczewski and Dominik Martin from Trelleborg, who provided valuable feedback to the students and made this event truly terrific.

Looking forward to the seminar next year!

The paper "Online Emotions During the Storming of the U.S. Capitol: Evidence from the Social Media Network Parler" has been accepted for presentation at the International AAAI Conference on Web and Social Media (AAAI ICWSM 2023). This project was conducted by Johannes Jakubik, Michael Voessing, Nicolas Proellochs (JLU Giessen), Dominik Baer (LMU Munich) and Stefan Feuerriegel (LMU Munich).

In this work, the authors examine the emotion dynamics on Parler during the storming of the U.S. Capitol on January 6, 2021 with regard to heterogeneity across time and users. The evaluation is based on a large-scale dataset from Parler, comprising of 717,300 posts from 144,003 users. The results indicate that the user base responded to the storming of the Capitol with an overall negative sentiment. Moreover, the study provides a cross-platform analysis and compares the emotion dynamics on Parler and Twitter. The findings point at a comparatively less negative response to the incidents on Parler compared to Twitter accompanied by higher levels of disapproval and outrage.

Congrats to the authors!

Patrick Hemmer presented the paper "A Meta-Analysis of the Utility of Explainable Artificial Intelligence in Human-AI Decision-Making" at the AAAI/ACM Conference on AI, Ethics, and Society (AIES 2022) in Oxford. The project was joint work with Max Schemmer, Maximilian Nitsche, Niklas Kühl and Michael Vössing.

The paper presents an initial synthesis of existing research that conducted user studies analyzing the effect of explainable artificial intelligence (XAI) assistance on human decision-making performance using a statistical meta-analysis. The analysis reveals a statistically positive impact of XAI assistance on users' performance. In this context, human-AI decision-making tends to yield better task performance on text data compared to tabular data. However, in the analysis, no effect of explanations on users' performance compared to sole AI predictions can be identified. These results give rise to future research investigating the underlying causes and contribute to further developing algorithms that effectively benefit human decision-makers by providing meaningful explanations.

Congrats to the authors!

Congratulations to Dr. Fabian Hunke for successfully completing his dissertation on "Analytics-Based Services: Conceptualization and Design Support" — probably the first defense where "Überraschungseier" were used as demonstration objects :-). A big thank you goes to the dissertation committee Orestis Terzidis, Wolf Fichtner, and Marc Wouters for — thanks to summerly weather — truly "heated" discussions...
Fabian, thanks for all your contributions to our group, and all the best of luck for the start into your professional life (directly applying what you have worked on at KIT!).

Just recently, Philipp Spitzer had the opportunity to present his paper on “Training Novices: The Role of Human-AI Collaboration and Knowledge Transfer” at the Human-Computer Collaboration and Teaming Workshop at ICML 2022 (International Conference on Machine Learning) in Baltimore, USA. With the increasing significance of knowledge within organizations, Niklas Kühl, Marc Goutier and Philipp outline how human-AI collaboration can be utilized to train novices on new tasks. Specifically, we conceptualize in a framework the different knowledge forms (explicit and tacit) in training novices through AI systems and outline a preliminary experiment design to investigate the capability of AI systems to be used as a trainer.

Patrick Hemmer, Michael Vössing, and Sebastian Schellhammer presented the paper “Forming Effective Human-AI Teams: Building Machine Learning Models that Complement the Capabilities of Multiple Experts” at the 31st International Joint Conference on Artificial Intelligence (IJCAI-ECAI 2022) in Vienna, Austria. The project was joint work with Johannes Jakubik and Gerhard Satzger.

In the paper, the authors showcase a system that facilitates the collaboration between humans and artificial intelligence. It consists of a classifier trained to complement the strengths and weaknesses of multiple human experts and an allocator that assigns task instances to the most suitable team member—either the classifier or one of the human experts. The proposed approach is evaluated in multiple experiments on public datasets with “synthetic” experts and a real-world medical dataset annotated by multiple radiologists. The system outperforms prior work and is more accurate than the best human expert or the classifier. Furthermore, it is flexibly adaptable to teams of varying sizes and different levels of human expert diversity.

Congrats to the authors!

During his Bachelor’s degree Joshua Holstein studied industrial engineering with a focus on mechanical engineering at the Technical University Darmstadt. Afterward, he earned his Master’s Degree at the Karlsruhe Institute of Technology (KIT) in Industrial Engineering and Management. As part of his studies, he spent a semester abroad at Reichman University in Herzliya (Israel). After finishing his master thesis at the Bayer AG, he joined the Applied AI lab of the Digital Service Innovation Group in July 2022 as a research asscociate. During his joined PhD with the Bayer AG, he researches how to lever data-centric AI methods in industrial settings such as manufacturing.

In June, Jakob Schoeffer presented the paper "There is not enough information": On the effects of explanations on perceptions of informational fairness and trustworthiness in automated decision-making at this year's ACM FAccT '22 conference in Seoul, Korea—the premier conference on topics related to fairness, accountability, and transparency in AI-based systems. This was joint work with Niklas Kuehl and Yvette Machowksi.

In this work, the authors conducted a human subject study to assess people’s perceptions of informational fairness (i.e., whether people think they are given adequate information on and explanation of the decision-making process and its outcomes) and trustworthiness of an automated lending system when provided with varying types and amounts of information about the system. From their quantitative analyses, they observe that different amounts of information as well as people’s (self-assessed) AI literacy significantly influence the perceived informational fairness, which, in turn, positively relates to perceived trustworthiness of the given system. A comprehensive analysis of qualitative feedback sheds light on people’s desiderata for explanations, among which are (i) consistency (both with people’s expectations and across different explanations), (ii) disclosure of monotonic relationships between features and outcome, and (iii) actionability of recommendations.

Congrats to the authors!

Smart product-service systems (sPSS) offer the opportunity to create additional value for all stakeholders involved. However, organizations often lack the resources, expertise, and practical guidance to develop, deploy, and maintain such complex solutions. With two publications, researchers of our research group “digital service innovation” address this topic. The studies are a result of the publicly funded “bi.smart” project.

How do small and medium-sized enterprises experience the potential of emerging technologies for the innovation and implementation smart product-service systems? What are the current barriers of adopting these technologies? This is the subject of this article, which will be published at the Conference of Business Informatics (CBI) in Amsterdam.

In the second article, the researchers build a maturity model for smart product-service systems that spans various dimensions - including technical enablers, the realization of value, and the integration into business. The research combines previous theoretical work with empirical findings from leading companies. The resulting model can support decision-makers in organizations in evaluating their own status quo, but also in identifying guidelines for the further development of their business model.

The authors look forward to sharing and discussing their findings with interested colleagues at CBI in Amsterdam (Netherlands) and CIRP CMS in Lugano (Switzerland).

Sie beschlossen, selbst eine Lösung zu finden und bewarben sich dazu mit Unterstützung durch KSRI/IISM und Innovation and Relations Management (IRM) für den DigitalChangeMaker Accelerator des Stifterverbands und der Reinhard Frank-Stiftung. Am 07.03.22 erhielten sie die Zusage. Nun geht es ans Werk. Herzlichen Glückwunsch an das Team!

Our research group successfully (co-)authored and presented 5 papers at „Internationale Tagung Wirtschaftsinformatik (WI22) – see below.

In particular, we congratulate the team around Daniel Heinz which ranked second for the Best Full Paper Award with their work on smart service systems!

Noteworthy for our talented students:  Jan Bode and team were able to place a paper in the student track, and last year’s terms “team project” team led by Lara Riefle turned their work into an academic contribution!

Congratulations to all authors – well done !!
