Leo Sylvio Rüdian

Doctoral Researcher

Leo Sylvio Rüdian received his Master‘s Degree in computer science from Humboldt University in October 2017. At his master thesis he explored the deanonymization of people by using fingerprinting approaches in social media.

Since November 2017 he is a research fellow at the Weizenbaum Institut and joined the research group of Prof. Pinkwart. During his studies, he focuses on machine learning in education, learning analytics and educational data mining.

His current investigations follow the aim to generate online courses by using textual inputs to overcome the limitation of the dependency to available online courses for educational recommender systems. He also investigates into adaption approaches (at micro and macro level) to personalize online courses according to the users' needs. Therefore, he examines culture and personality traits in learning systems for user modeling.
