The Alma Mater Europaea (AMEU) in Salzburg, Austria, offers a limited residency Ph.D. in Applied Artificial Intelligence. The program is 3 years, and the tuition is EUR 12,000 per year. I don't know much about this university, but it seems to be legit. URL: https://download.almamater.si/brochure/aai/AMEUaaibrochure.pdf
