Kai Polsterer, head of the Astroinformatics (AIN) group at HITS, was selected as member of an international team at the International Space Science Institute (ISSI).

The ISSI is an Institute of Advanced Study where scientists from all over the world meet in a multi- and interdisciplinary setting to reach out for new scientific horizons. The program of ISSI covers a wide spectrum of disciplines including the physics of the solar system and planetary sciences to astrophysics and cosmology, and from Earth sciences to astrobiology. ISSI offers a forum for space scientists, ground-based observers and experimenters, theorists, and modellers to work together.

New machine learning techniques for big data in astronomy

The International teams are composed of about 8-15 scientists of different laboratories, nationalities and expertise. They hold a series of two to three one-week meetings over a period of 12 to 18 months. The aim is to carry out a joint research project leading to publications in scientific journals. Teams are set up in response to an Annual Call by ISSI.
In 2021, the Science Committee selected more than 20 teams, including this group which will revisit the standard star-formation paradigm and the evolutionary scheme of young stars, using new machine learning techniques applicable to big data. The team comprises experts in star formation, survey data, big data analysis, and machine learning to use multi-wavelength data to derive a new evolutionary scheme for young stellar evolution, among them HITS group leader Kai Polsterer, who is an expert in machine learning.

About HITS

The Heidelberg Institute for Theoretical Studies (HITS) was established in 2010 by the physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural sciences, mathematics and computer science, with a focus on the processing, structuring, and analyzing of large amounts of complex data and the development of computational methods and software. The research fields range from molecular biology to astrophysics. The shareholders of HITS are the HITS-Stiftung, which is a subsidiary of the Klaus Tschira Foundation, Heidelberg University and the Karlsruhe Institute of Technology (KIT). HITS also cooperates with other universities and research institutes and with industrial partners. The base funding of HITS is provided by the HITS Stiftung with funds received from the Klaus Tschira Foundation. The primary external funding agencies are the Federal Ministry of Education and Research (BMBF), the German Research Foundation (DFG), and the European Union.
