低秩矩阵估计的贝叶斯方法:综述与理论研究

Bayesian methods for low-rank matrix estimation: short survey and theoretical study

Pierre Alquier

摘要:

低秩矩阵估计问题由于其具有挑战性的应用而受到广泛关注。在秩罚方法和凸松弛方法的理论和应用方面已经做了大量的工作。然而,只有少数论文考虑贝叶斯估计。在本文中,我们回顾了不同类型的先验矩阵,有利于低秩。我们还证明了所得到的贝叶斯估计,在适当的假设下,享有相同的最优性性质的基础上惩罚。

英文摘要:

The problem of low-rank matrix estimation recently received a lot of attention due to challenging applications. A lot of work has been done on rank-penalized methods and convex relaxation, both on the theoretical and applied sides. However, only a few papers considered Bayesian estimation. In this paper, we review the different type of priors considered on matrices to favour low-rank. We also prove that the obtained Bayesian estimators, under suitable assumptions, enjoys the same optimality properties as the ones based on penalization.
