Filippo Betello
Hello everyone!!! I am a third-year PhD student in Data Science at Sapienza University of Rome in the Department of Computer, Control and Management Engineering. I work under the guidance of Professor Fabrizio Silvestri and collaborate with the RSTless group. My research interests include recommender systems, LLMs and IR. Previously, I received my master's degree in Artificial Intelligence and Robotics from Sapienza University of Rome.
