ABSTRACT

With the rapid development of information technology and Internet technology, how to dig out products or services that users are interested in from massive information and display them in a personalized manner according to the score prediction results has become a current research hotspot. Collaborative filtering is currently a technology commonly used in personalized recommendation systems. Its basic idea is to use users with the same interests in the past to choose similar products in the future. This paper proposes a personalized product recommendation model based on deep neural networks and dynamic collaborative filtering. This model uses the BERT model and two-way GRU to replace the traditional word vector text processing method, which can effectively reduce the impact of data sparsity and achieve deep hidden feature extraction. The scoring matrix is predicted by the coupled CNN network, and the product scoring prediction is realized based on the dynamic collaborate filtering of the fusion time series items. The experimental results verify that the model reduces the impact of data sparsity and cold start problems, takes into account the changes in user interest over time, and has obvious advantages in recommendation accuracy.
