Program.

The first day consists of a series of plenary talks by academic researchers and industry practitioners. Throughout the day, there will be poster sessions and many network opportunities. This will be followed by a reception and conference dinner. 

On the second day,  we will have thematic breakout sessions to delve deeper into current issues in recommender systems research. These breakout sessions will bring together early career researchers and seasoned experts to give and receive feedback on work-in-progress, and discuss future collaborations.
