🥈Two-layered recommender system methodology: a prize-winning solution

A Cinema Challenge hackathon was held from 14 to 22 November of 2020. It was dedicated to creating solutions for online theatre sweet.tv. I managed to create a prize-winning solution for challenge 2 and decided to share my methodology. The task was to predict top-5 tv-programs for each user based on his view history. TV-program was considered watched if the user watched over 80% of it and did not change the channel.
