Privacy-preserving Trajectory Generation Algorithm Considering Utility based on Semantic Similarity Awareness

2022

Location-based service recommendations usually need to collect and analyze the location information of trajectories generated by users with smart phones or wearable devices. It is easy to cause the location privacy leaks. The current location …

Multi-graph Convolutional Feature Transfer for Cross-domain Recommendation

2022 · 2022 International Joint Conference on Neural Networks (IJCNN)

Cross-domain recommendation(CDR) is an effective method to alleviate the data sparsity problem in the recommendation system. How to learn common and domain-specific feature embeddings of users and items is a challenge especially where the two …

Meta-Learning for Debiasing Recommendation using Simulated Uniform Data

2024

The recommendation system is subject to various biases, resulting in different training and testing data distribution. Most previous work either relies on a part of uniform data to guide model training which is difficult to …
