Temporal Modeling of User Preferences in Recommender System

Serhii Chalyi, Volodymyr Leshchynskyi
2020 International Conference on Information Control Systems & Technologies  
The adaptation of the model is performed when describing a temporal pattern of the evolution of user requirements by choosing a time interval within which the initial temporal rules are formed.  ...  The model is distinct by the use of temporal rules for building a temporal pattern of periodic changes in user preferences or a description of user requirements' evolution.  ...  The metric 3 dsim allows highlighting a group of users with similar behaviour who have shown interest in the subject i x . Therefore, this metric is focused on building item-based recommendations.  ...

Sequential Recommendation with Graph Neural Networks [article]

Jianxin Chang, Chen Gao, Yu Zheng, Yiqun Hui, Yanan Niu, Yang Song, Depeng Jin, Yong Li
2021 arXiv   pre-print
In this work, we propose a graph neural network model called SURGE (short for SeqUential Recommendation with Graph neural nEtworks) to address these two issues.  ...  In addition, users' dynamic preferences often change rapidly over time, and hence it is difficult to capture user patterns in their historical sequences.  ...  We study how SURGE improves the recommendation for those users with long behavior records.  ...
