Research into AI has been carried out at LiU since the early 1970s. The current areas of focus are intelligent decision-support systems, machine learning, and robots, drones and other machines that collaborate with each other and with humans. 

Development has been rapid since LiU appointed Sweden’s first professor in computer science, Erik Sandewall, in 1975. He had presented his doctoral thesis in 1969 in the new subject “artificial intelligence”. At the time, research was focused onto expert systems and knowledge transfer. The focus today has shifted to machine learning, deep learning and systems that include reasoning and decision-making processes - AI-enabled systems.

At LiU, world-leading research is conducted in several important fields of AI. Computer Vision - deep learning in which computers, with the aid of advanced image processing and AI, can draw their own conclusions - is one strong field, while another is knowledge systems and advanced decision support, which requires logical reasoning. A third field is research into the role of humans in the systems, together with how we can maintain the knowledge required to be able to take over if the systems fail for any reason.

LiU researchers have also demonstrated how autonomous drones can work together with each other and with humans in order to provide aid to people in an emergency in inaccessible parts of the Alps. Demonstration projects at an even larger scale are under way within the huge research initiative WASP, the Wallenberg Autonomous Systems and Software Program, where LiU is the host university. A ten-year investment into AI is being carried out within the framework of WASP, financed by SEK 1 billion from the Knut and Alice Wallenberg Foundation.

Artificial intelligence in this case deals with creating programs and systems that think or act as intelligent people. Related research can be found in the fields of autonomous systems, robotics, man-machine interaction, and statistics, which at LiU has a strong focus onto machine learning.

LiU is also home to AIDA, the Analytic Imaging Diagnostic Arena, a Swedish arena for research and innovation in artificial intelligence for medical image analysis. AIDA is a forum in which the academic world, the healthcare system and industry meet to translate technical advances in AI to patient benefit.
