March 2025: Visit from Landau!

Dominik researches the psychometric properties of slider scales.

Dominik is a PhD student at the RPTU in Landau and part of Tanja Lischetzke's research group. In his research, he focuses on slider scales (or visual analog scales) in different contexts. Among other things, he investigates the psychometric properties of slider and Likert scales in ambulatory assessment studies, for example in terms of measurement invariance and reliability.in March, he visited the Department of Statistics and Data Science, where he worked with Mirka Henninger on a model for capturing response styles in slider scales.

March 12-14, 2025: Research meeting

The SDS team in Günsberg, Solothurn

The SDS team spent three days at the research meeting in idyllic Günsberg near Solothurn. We enjoyed a series of interesting presentations, for example from Dr. Judith Rode, who gave us an insight into the coordination of research and clinical practice. There were also heated discussions on how to deal with p-values in psychological research and the sense and nonsense of post-hoc power analyses. At least as heated were (some of) the dinner preperations in the cooking teams, which nevertheless ended in a complete success! On Thursday evening, Linus, part-time game master, was allowed to give free rein to his creativity at the joint game evening, which we will remember for a long time to come. We rounded off our stay with a short hike to the "Hofbergli" mountain restaurant, organized by our hiking guide Jan.

February 20-14, 2025: Winter School Fribourg

Visual emotion recognition using AI: Linus, Jan and Constantin develop new app!

Bienvenue à Fribourg! Constantin, Linus and Jan spent a week at the winter school of the University of Fribourg, which focused on the subjects of data analytics and machine learning. During this week, they received an introduction to the Python programming language for data analysis and the use of machine learning. At the end, they learned about the infinite possibilities of deep learning with neural networks and worked with non-tabular data such as images and text. They became developers of their own app, which can be used to recognize emotions based on facial expressions. If a book is ever written about the great AI developers Constantin, Linus and Jan, this will be the week the story began.

December 17, 2024: Year-end gathering

Year-end gathering of the SDS center

Today, we look back on the first year of the SDS and celebrate with our team, surrounded by countless mezze platters. It has been a year of settling in, getting to know each other and taking off. The autumn semester saw the start of the team's teaching activities and various research projects in the field of machine learning. At the same time, we had the pleasure of welcoming many researchers as guests.
We are excited about the challenges and opportunities that the coming year holds for our SDS team.

We would like to thank you very much for the nomination and are delighted that the lecture is so appreciated by the students! We wish all students a relaxing semester vacation and look forward to a continuation in the spring semester 2025!

November, 2024: Visit from Leuven!

Jordan researches machine learning in ESM studies.

Jordan is a PhD student at KU Leuven under the supervision of Eva Ceulemans and Ginette Lafit. His research focuses on longitudinal models and data, particularly in Experience Sampling Methods (ESM), where he develops methods for sample size planning, data preprocessing, and quality assessments. Additionally, he investigates how ESM characteristics (e.g., designs, missing data patterns) influence model performance. This November, he is visiting Mirka Henninger's group to explore machine learning and interpretable methods for ESM studies.

October 3, 2024: Inaugural lecture

"From sumscore to machine learning... and back?"

On October 3, 2024, Mirka's inaugural lecture titled "From Sumscore to Machine Learning... and Back" took place at the Alte Universität. During the lecture, the faculty and guests were taken on a journey through time, from the sumscore to modern time series data analysis.

We are very pleased that so many people are interested in our research and sincerely thank you for coming! more

Jan, Linus, Constantin and Mirka attend the DGPs conference.

In September, Linus, Jan and Mirka presented their researches as posters at the DGPs conference. Linus presented his master's thesis on the subject of decision trees for multilevel data, Jan his internship project on effect sizes in model-based recursive partitioning methods and Mirka her researches on local interpretation techniques for machine learning models. We are looking forward to many exciting discussions and a good time in Vienna - despite all the rain!

September 1, 2024: Welcome Constantin!

Constantin enriches our SDS team as a PhD student.

Constantin has a bachelor's and master's degree in psychology and is now pursuing his doctorate here. During his studies, he has gained some experience with simulation studies, for example on factor analysis with EEG data, variable selection with L1 regression or stability assessment of decision trees. His research interests lie in particular in machine learning methods and longitudinal data. Constantin will supervise final theses in the bachelor's program and hold seminars in the master's program, thus contributing to teaching activities.

September 1, 2024: Welcome (back) Jan!
