Abstract

Most sequential recommendation systems(SRS) assume that the next item to be predicted is related to the user's previous input. However, in real scenarios, users may click items inconsistent with their own interests and preferences(unreliable instances) by mistake during browsing. This paper proposed a sequential recommendation algorithm based on Gaussian distribution modeling to solve this problem. Firstly, the algorithm extracted the input sequence patterns by reducing the uncertainty of input items through an uncertainty aware graph ensemble network(UAN) with multiple heads of self-attention. Secondly, it modeled the extracted input sequence pattern as a Gaussian distribution, and obtained the dynamic user's preferences and the uncertainty of preferences in the sequence information. Then, it extended the traditional recommended objective function to a sampling loss function and an uncertainty regularizer, and gave each training instance appropriate uncertainty. Finally, it removed the unreliable examples with high loss and low uncertainty to enhance the accuracy of sequence recommendation. It tested the algorithm on three open datasets, Book-Crossing, MovieLens-1M and Steam. The results show that the algorithm has achieved an improvement of about 5.3% compared with the baseline with good effects, and has obtained better sequential recommendation results. The proposed algorithm can improve the recommendation accuracy by effectively reducing the uncertainty of input sequence information.
