AI总结:

提出FedDMF算法,通过联邦学习训练深度矩阵分解模型并仅共享项目向量,实现无需用户匹配的隐私保护用户属性预测,在MovieLens数据集上达到FedAvg的96%准确率。

摘要:

用户属性预测是各行业中的一项关键任务。然而,由于隐私问题以及关于个人身份信息的法律要求,跨不同组织共享用户数据面临挑战。欧盟的《通用数据保护条例》(GDPR)和《中华人民共和国个人信息保护法》等法规对数据共享施加了限制。为了在遵守法律要求的同时利用来自多个客户端的特征,联邦学习算法已被提出。这些算法旨在不直接共享数据的情况下预测用户属性。然而,现有方法通常依赖于跨公司匹配用户,这可能导致不诚实的合作伙伴发现用户列表,或无法利用所有可用特征。在本文中,我们提出了一种无需用户匹配即可预测用户属性的新算法。我们的方法涉及在不同客户端上训练深度矩阵分解模型,并仅共享项目向量。这使得我们能够在不共享用户向量的情况下预测用户属性。该算法使用公开可用的MovieLens数据集进行评估,并证明其达到了与FedAvg算法相似的性能,达到了单个模型准确率的96%。所提出的算法特别适用于改进客户定位和增强整体客户体验。本文通过提供一种解决该领域一些最紧迫隐私问题的新算法,对用户属性预测领域做出了宝贵贡献。

英文摘要:

User attribute prediction is a crucial task in various industries. However, sharing user data across different organizations faces challenges due to privacy concerns and legal requirements regarding personally identifiable information. Regulations such as the General Data Protection Regulation (GDPR) in the European Union and the Personal Information Protection Law of the People's Republic of China impose restrictions on data sharing. To address the need for utilizing features from multiple clients while adhering to legal requirements, federated learning algorithms have been proposed. These algorithms aim to predict user attributes without directly sharing the data. However, existing approaches typically rely on matching users across companies, which can result in dishonest partners discovering user lists or the inability to utilize all available features. In this paper, we propose a novel algorithm for predicting user attributes without requiring user matching. Our approach involves training deep matrix factorization models on different clients and sharing only the item vectors. This allows us to predict user attributes without sharing the user vectors themselves. The algorithm is evaluated using the publicly available MovieLens dataset and demonstrate that it achieves similar performance to the FedAvg algorithm, reaching 96% of a single model's accuracy. The proposed algorithm is particularly well-suited for improving customer targeting and enhancing the overall customer experience. This paper presents a valuable contribution to the field of user attribute prediction by offering a novel algorithm that addresses some of the most pressing privacy concerns in this area.
