Matthias Schubert

Prof. Dr.

Principal Investigator

Matthias Schubert

is Professor at the Database Systems and Data Mining AI Lab and head of ‘AI-beyond: Research Group for Spatial AI’ at LMU Munich.

Reinforcement learning can learn powerful policies which enable autonomous systems to dynamically adapt to unknown situations and still perform well in maximizing expected rewards. His group develops novel solutions for spatial mobility tasks such as resource collection and allocation in highly dynamic environments. They aim to make their agents as versatile to adapt to changed conditions and variations of the environment. They further investigate risk and constraints to enforce stable outcomes in financial settings such as portfolio allocation.
