The first MoST-Rec Workshop @ CIKM 2019 is a place for discussing and exchanging recent advances and open challenges between the Model-Selection and Parameter Tuning community and the Recommendation Systems community.

Recommender systems (RS) have attracted strong attention of the machine learning community, especially within the last decades. Researchers have developed various algorithms proven to have good performance in the laboratory environment; however, applying them to real business cases is typically more difficult.

This workshop addresses the issues of algorithm selection and parameter tuning for recommender systems. The goal is to bring together researchers from the machine learning community with the industry representatives in order to exchange information on current challenges, constraints and ideas from both domains.

The half-day workshop will feature invited talks, contributed paper presentations and demonstrations/posters.

New: All accepted papers will be considered for inclusion in a special issue of the Springer International Journal of Data Science and Analytics (JDSA). Details will be included here soon.
