Given the sparsity characteristics of most recommendation datasets, researchers have introduced SSL methods into GNN-based models. For example, Zhou et al. [47] designed four self-supervised optimization objectives to learn the correlations in the context information of user–item interaction sequences...
Many researchers have improved the performance of weighted hybrid recommendations based on collaborative filters and content-based algorithms. In this task how to optimize the weight is one key for the weighted hybridization, and that is the topic to which we pay more attention in this paper. ...

Relationships between entities may reflect researchers' expertise or social relationships to some extent. For example, a researcher may like others' posted articles. The liking relationship may also reflect this researcher's interest to some extent. Therefore, we need to systematically integrate ...
Future research will focus on model validation, algorithm implementation and performance evaluation of solutions proposed in “Section 6Existing problems and countermeasures analysis”. Thereby, it provides new ideas and new methods for solving the open problems involved in the recommendation system to imp...
Whereas in data science and computer science, researchers call this “collaborative filtering.” Advantages to Collaborative Filtering Gives a great starting point for most visitors Provides serendipity — a way to explore and find what you weren’t looking for Disadvantages to Collaborative Filtering ...
For people who were in your lab but have since moved on—ask for a written summary of their current work, future plans, and why they are interested in the position for which you are writing the letter. ♦ For students who are not in your lab or department but who were in one of ...
When people see that they can control their privacy settings on websites and apps that offer entertainment or product recommendations, they tend to be more trusting of those sites, according to researchers.
And finally, the conclusions and future work are given in Section “Conclusion and Future Work”. Related work Many researchers pay attention to the development of POI recommendation because of the variety of applications in real life. POI recommendation was studied on the check-in behavior of ...
Deep learning can be further applied to a great number of potential recommendation scenarios. Here is a brief discussion that highlights promising future directions. Efficiency and scalability.For industry-grade recommendation systems, people should not only consider a model’s accuracy, but al...
