Data-Limited Learning of Complex Dynamical Systems
About the project
In the project Data-Limited Learning of Complex Dynamical Systems (DLL), we develop methods and tools for how to learn to control complex dynamical systems using limited data samples. In contrast to traditional machine learning techniques that require large amounts of data for training, the objective of this project is to utilize a priori knowledge of the system and combine such structural knowledge reliably with a limited number of data samples.
The project focuses on two application domains: (i) continuous bioprocessing for safer and more efficient production of biopharmaceuticals and (ii) reinforcement learning of cyber-physical systems in general and robotics in particular. In these domains, probing large amounts of data from the system can be very expensive or even impossible without wearing out the system.
Recent years have witnessed spectacular successes in applying machine learning tools to the decision-making and control of complex dynamical systems. These techniques typically combine reinforcement learning with large neural networks, thus requiring a tremendous amount of training data, even to learn simple tasks. Their applications have been mainly limited to specific scenarios, such as board and video games, where generating and gathering data is inexpensive. However, in many biological or physical application domains, data is limited, and probing the system for more data can be very expensive or even impossible without destroying the system.
This project involves co-PIs and researchers from different disciplines, including computer science, automatic control, machine learning, and biotechnology. To make the interaction as fruitful as possible, the project is divided into three sub-projects: continuous bioprocessing, (ii) reinforcement learning in cyber-physical systems, and (iii) theory. The research involves fundamental theory and practical applications, including involvement from industrial partners. The collaboration between the research team at Digital Futures and the Competence Centre for Advanced BioProduction (AdBIOPRO) will establish a strong, visible and sustainable research environment that overarch digitalization and life science research at KTH.
