Prof. Dr. Tobias Friedrich

Media Collection

The primary output of the Algorithm Engineering group are peer-reviewed research papers in conference proceedings and scientific journals. Unfortunately, most of this work is not very visual. This motivates us to collect some visual appearances of the research group on this page. Most headings and pictures link to their respective source. Recordings of research talks are in English. Most other videos are in German.

Recorded Talks

Due to the SARS-Covid-2 outbreak, many conferences switched to online solutions in order to be held regardless of the situation. As a result, many talks were prerecorded and then presented. Feel free to enjoy the prerecoded talks of our group members one more time!

December 2021: WINE '21 hosted by the Algorithm Engineering Group

Hosted by the Algorithm Engineering group, researchers gathered in the virtual Hasso Plattner Institute to participate in the Conference on Web and Internet Economics '21 (WINE). This conference serves as interdisciplinary forum for the exchange of ideas and results on incentives and computation arising from theoretical computer science, artificial intelligence, operations research and economics. Recordings of the event can be found on Tele-Task.

October 2021: IREBS Symposium on Real Estate

The IREBS Immobilien-Symposium (engl. IREBS Real Estate Symposium) brings together real estate experts from various directions. In its 17th edition, the Algorithm Engineering group contributes a video showing ways compliant with German law to automate every day real estate valuations, intensifying the use of artificial intelligence on the way. This paves the way for an automated and data driven real estate valuation process in the future. This is joint work with the DSV Sparkassenverlag, the Real Estate Management group led by Prof. Wolfgang Schäfers at the International Real Estate Business School (IREBS) of the University of Regensburg, Germany, and the Information System group of the Hasso Plattner Institute led by Prof. Felix Naumann.
