In Proceedings of the 43rd International ACM SIGIR Conference on Research and … WebFederated Recommender Systems (FedRecs) are considered privacy-preservingtechniques to collaboratively learn a recommendation model without sharing userdata. Since all participants can directly influence the systems by uploadinggradients, FedRecs are vulnerable to poisoning attacks of malicious clients.However, most existing poisoning …
WebApr 1, 2024 · This paper proposes a new social recommendation system based on a light graph convolution network, called ’SocialLGN’.
