摘要:

矩阵分解是推荐系统中最常用的技术之一。随着推荐系统在电子商务购物、在线视频等方面的推广,分布式推荐系统得到了广泛推广,多源数据的隐私问题变得越来越重要。基于联邦学习技术,提出了一种共享矩阵分解方案SharedMF。首先构建了一个分布式推荐系统,然后采用秘密共享技术保护本地数据的隐私。实验结果表明,与现有的同态加密方法相比,该方法在不泄露隐私的情况下,具有更快的执行速度,能够更好地适应大数据量的推荐场景。

英文摘要:

Matrix factorization is one of the most commonly used technologies in recommendation system. With the promotion of recommendation system in e-commerce shopping, online video and other aspects, distributed recommendation system has been widely promoted, and the privacy problem of multi-source data becomes more and more important. Based on Federated learning technology, this paper proposes a shared matrix factorization scheme called SharedMF. Firstly, a distributed recommendation system is built, and then secret sharing technology is used to protect the privacy of local data. Experimental results show that compared with the existing homomorphic encryption methods, our method can have faster execution speed without privacy disclosure, and can better adapt to recommendation scenarios with large amount of data.
