Alessandro B. Melchiorre


I am a Ph.D. student at the Institute of Computational Perception and at the Multimedia Mining and Search Group at the Johannes Kepler University Linz, Austria.

I studied Engineering in Computer Science in my Bachelor at Università degli Studi di Napoli Federico II and in my Master at Sapienza - Università di Roma where I both graduated with full marks.

My main interests revolve around the topics of recommender system algorithms, explainability in AI, and bias & fairness. I am particularly enthusiastic about developing interpretable models and explainability methods for recommender systems, especially in the music domain. I am also interested in investigating the relationships between users’ characteristics and music preference and consumption.
