Michal Kompan

Research areas: personalised recommendations, machine learning, artificial intelligence, information retrieval

Position: Chief Research & Innovations Officer

Michal focuses on recommender systems, machine learning, user modeling, and information retrieval. His research is focused on predictive modeling and customer behavior (e.g., churn prediction, next-item or multi-objective recommendation), as well as content-based adaptive models. He specifically addresses the recommender system in e-commerce, for instance the complementary products recommendations.

He participated in several research projects funded by the Slovak government or European union. As a principal investigator he led the “Modelling, prediction and evaluation of user behavior based on the web interaction for adaptation and personalization” (APVV), “European digital innovation hub Hopero” (Digital Europe) and “Trustworthy Multi-Objective and Multi-Stakeholder Recommenders” (Recovery and Resilience Plan) projects. Additionally, as a researcher he participated in: 5 projects funded by the Scientific and grant agency of Slovak Republic, 3 projects funded by the Slovak research and development agency and 4 projects funded by the European Union (Horizon 2020, Horizon Europe).

As a teacher, he has supervised more than 50 Bachelor’s and Master’s theses. To support the community, he has served as a reviewer or/and program committee member at several international conferences.

He is also a member of IEEE and senior member ACM and the Slovak informatics society. He has participated in many research projects in co-operation with industry such as Symbiosy by HB Reavis, Exponea, ZlavaDna, SME, Piano media and Orange SK.
