On the 8th 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.

Researchers overestimate their own honesty

The average researcher thinks they are better than their colleagues at following good research practice. They also think that their own research field is better than other fields. This is shown in a new study at Linköping University.

Physical fitness in adolescence linked to less atherosclerosis later

Men who were physically fit when they were young had a lower risk of atherosclerosis almost 40 years later. These findings suggest that atherosclerosis is one of the mechanisms behind the link between physical fitness and cardiovascular disease.
