Reinforcement Learning for Complex Applications of Automation Technology (ReLkat)

Saving energy plays a central role in all industries for ecological and economic reasons. With intelligent local control in buildings, infrastructure and production, efficiency can be significantly improved. Instead of elaborate manual configuration, their automation using machine learning (ML) is an option. An alternative to the currently popular cloud approaches is local learning, with reinforcement learning (RL) playing a key role.

The research project ReLkat examines the possibilities of introducing RL into locally operating systems. Along with the development of new mathematical processes, RL basic modules for the IoT and the use of RL in industrial control technology are created. A slim RL library is being newly developed for use on a large number of IoT devices.

With XONBOT®, Signal Cruncher already has a field-tested RL analysis core that is to be expanded for IoT applications. The core is intended to be applied to a broad class of control tasks. The Fraunhofer IPK researches the XONBOT developments and their possible uses in the field of smart factories. How can industrial controls be connected to RL to solve current industrial problems? The answer includes integration concepts, uniform optimization descriptions and integration into industrial communication technology. A testbed enables simulation-based testing of all developed modules. WIAS Berlin is involved in this project with a focus on optimization under complex constraints and TU Berlin for learning processes using hierarchical tensor networks.
