                                      The past decade in recommender systems has been dominated by the usage of implicit signals to
                                      infer latent user features. The advantage being that implicit signals are readily available and in large
                                      quantities. However, such modeling is purely behavioural and lacks depth in order to understand the
                                      cognitive reasoning behind user choices and preferences. In this talk I will demonstrate how cognitive
                                      models, inspired from psychology, can be beneficial for various challenges in recommender systems,
                                      from the cold start problem, through context-aware recommendations to explanations.

                                      Marko Tkalcic is associate professor at the Faculty of Mathematics, Natural Sciences and Information
                                      Technologies (FAMNIT) at the University of Primorska in Koper, Slovenia. He aims at improving person-
                                      alized services (e.g. recommender systems) through the usage of psychological models in personalization
                                      algorithms. To achieve this, he uses diverse research methodologies, including data mining, machine
                                      learning, and user studies. More info at http://markotkalcic.com/.
