Cold-start Bundle Recommendation via Popularity-based Coalescence and Curriculum Heating

1 code implementation5 Oct 2023 Hyunsik Jeon, Jong-eun Lee, Jeongin Yun, U Kang

To estimate the user-bundle relationship more accurately, CoHeat addresses the highly skewed distribution of bundle interactions through a popularity-based coalescence approach, which incorporates historical and affiliation information based on the bundle's popularity.

Diversely Regularized Matrix Factorization for Accurate and Aggregately Diversified Recommendation

1 code implementation19 Oct 2022 Jongjin Kim, Hyunsik Jeon, Jaeri Lee, U Kang

However, it is challenging to tackle aggregate-level diversity with a matrix factorization (MF), one of the most common recommendation model, since skewed real world data lead to skewed recommendation results of MF.
