摘要:

隐私保护推荐最近获得了发展势头,因为分散的用户数据越来越难以被推荐服务提供商收集,由于对用户隐私和数据安全的严重关注。严格的政府法规,如欧洲的通用数据隐私条例(GDPR),进一步加剧了这种情况。联邦学习(FL)是一种新开发的隐私保护机器学习范式,用于在不损害数据安全和隐私的情况下桥接数据存储库。因此,人们提出了许多联邦推荐(FedRec)算法来实现个性化的隐私保护推荐。然而,现有的FedRec算法大多是从传统的协同过滤(CF)方法扩展而来,不能很好地解决冷启动问题。此外,它们的性能开销w.r.t.与集中式推荐相比,在联合设置中训练的模型准确性通常是不可忽略的。本文研究了这个问题,并提出了FL-MV-DSSM,一个通用的基于内容的联邦多视图推荐框架,不仅解决了冷启动问题,但也显着提高推荐性能,通过学习联邦模型从多个数据源捕获更丰富的用户级功能。FL-MV-DSSM提出的新的联合多视图设置打开了新的使用模型,并在推荐场景中为FL带来了新的安全挑战。我们证明了\xxx的安全性保证,并在FL-MV-DSSM及其变化与公共数据集的实证评估证明了其有效性。如果这篇论文被接受,我们的代码将被发布。

英文摘要:

Privacy-preserving recommendations are recently gaining momentum, since the decentralized user data is increasingly harder to collect, by recommendation service providers, due to the serious concerns over user privacy and data security. This situation is further exacerbated by the strict government regulations such as Europe's General Data Privacy Regulations(GDPR). Federated Learning(FL) is a newly developed privacy-preserving machine learning paradigm to bridge data repositories without compromising data security and privacy. Thus many federated recommendation(FedRec) algorithms have been proposed to realize personalized privacy-preserving recommendations. However, existing FedRec algorithms, mostly extended from traditional collaborative filtering(CF) method, cannot address cold-start problem well. In addition, their performance overhead w.r.t. model accuracy, trained in a federated setting, is often non-negligible comparing to centralized recommendations. This paper studies this issue and presents FL-MV-DSSM, a generic content-based federated multi-view recommendation framework that not only addresses the cold-start problem, but also significantly boosts the recommendation performance by learning a federated model from multiple data source for capturing richer user-level features. The new federated multi-view setting, proposed by FL-MV-DSSM, opens new usage models and brings in new security challenges to FL in recommendation scenarios. We prove the security guarantees of \xxx, and empirical evaluations on FL-MV-DSSM and its variations with public datasets demonstrate its effectiveness. Our codes will be released if this paper is accepted.
