[introductory/intermediate] Recommender Systems

Summary

Research in the field of recommender systems (recsys) has been very active in recent years. Recsys are embedded in a lot of daily activities and are considered to be a very challenging machine learning problem. Although machine learning has been profoundly impacted by deep learning, its impact on recommender systems was slow and not significant until recently. In this course we first introduce recsys, their challenges, tasks, domains, and classic approaches. We will then discuss the reasons to use deep learning algorithms for recsys and explore the application of a variety of deep learning models for common recsys challenges. Finally, we will deep dive into some specific recsys tasks and domains that utilize deep learning. This includes context-aware recommender systems, session-based recommendations, bundle recommendations, etc. Finally, we will discuss recent advances and future directions.

Syllabus

  • Introduction to recommender systems – classic approaches.
  • Deep learning for recommender systems – challenges and opportunities.
  • Use cases – deep dive on specific recommender systems’ tasks and domains.
  • Recent advances and outlook to future research directions.

Short bio

Bracha Shapira is a full professor at the Department of Software and Information Systems Engineering at Ben-Gurion University of the Negev in Israel, and served as the head of the department for 6 years. She works on application of machine learning to various domains and specifically to recommender systems. She studies various recommender systems algorithmic aspects, such as context aware recommenders, bundle recommendations, evaluation aspects, explanability and more. She has published about 250 papers in journals and peer-reviewed conferences and registered several patents. She co-edited the popular Handbook of Recommender Systems (now 3rd edition). She regularly takes roles in leading conferences, such as PC chair at ACM Recsys 22, Doctoral Consortium chair at WSDM 2021, and Area chair at ACL 2019. Bracha collaborates with industry – she led numerous research projects at the Deutsche Telekom Lab at BGU and was the head of AI at a startup company (Sparks-AB).
