On March 4–6, 2020, the final of the first Olympiad in artificial intelligence was held in Khoroshkol - a joint direction of the Olympiad of the NTI Club Movement and the AI Academy for schoolchildren.
At the final, the participants had to build a recommendation system for Sberbank clients. We worked on the task for 2 days (about 14.5 hours in total) in teams of 2 people.
