Denis presented our paper The Dark Matter of Serendipity in Recommender Systems at CHIIR 2024.
We work on the intersection of machine learning, information retrieval and human-computer interaction. In particular, we focus on all aspects of recommendation, user modelling and personalisation. We are part of the Department of Computer Science at the University of Helsinki.
