On the 8th of December, Johan Källström at the Department of Computer and Information Science defended his thesis about reinforcement learning, a machine learning method, and its utility for simulation-based pilot training. Here is a brief summary of the thesis.

Team training in complex domains often requires a substantial number of resources, e.g. vehicles, machines, and role-players. For this reason, it may be difficult to realise efficient and effective training scenarios in a real-world setting. Instead, part of the training can be conducted in synthetic, computer-generated environments.

Reinforcement learning for improved utility of simulation-based training

In his doctoral thesis, Johan Källström has studied how the machine learning method reinforcement learning can be used to construct synthetic agents in support of simulation-based pilot training. The focus has been on methods that can find a balance between multiple objectives, for instance different training objectives, to optimise the utility of the user. The thesis presents agents that can provide support to instructors by efficient learning of a set of Pareto optimal policies, and by efficient adaptation to user needs in operational training systems.
