Session 3 of 2023 ACM RecSys Summer School: Group recommendation (parte 1) by Prof. Ludovico Boratto

Day 2 of the 2023 RecSys Summer School in Copenhagen! Today, Ludovico Boratto kicks off the day with a double session on group recommendation! #rsss2023 #recsys

People at UMAP, while enjoying the lovely #StRaphaelResort , come to listen about User Profiling w/ GNNs and Related Beyond-Accuracy Perspectives.

Start: Jun 26, 2023, 9 am.
Info and outline: beyondaccuracy-userprofiling.github.io/tutorial-umap2…

I will present it w/ Ludovico Boratto and Ernesto W. De Luca

Hi, #ECIR23 Attenders 👋! On April 5 in Reproducibility 2 Ludovico Boratto will present our paper about reproducibility and beyond accuracy evaluation for explainable RS. Since nowadays Tweets are required to mention the word AI see an AI-generated summary shorturl.at/GLOWY

In 'MOReGIn: Multi-Objective Recommendation
at the Global and Individual Levels', with Elizabeth Gómez, David Contreras, and Maria Salamó, we regulate the recommendation lists to guarantee both global and individual objectives, while preserving effectiveness.

Our tutorial at UMAP finally happened.
And we just released our slides.

Thanks to all the participants. I really hope you enjoyed our content!
