摘要:

在本文中,我们介绍了第一种方法,(1)可以完成完全缺失行和列的核矩阵,而不是个别缺失的核值,(2)不需要任何核是先验完整的,(3)可以处理非线性核。这些方面在实际应用中是必要的,例如集成遗留数据集,在传感器故障下学习,以及在某些视图的测量成本高昂时学习。所提出的方法预测丢失的行建模内的视图和视图之间的关系内核值。我们表明,无论是在模拟数据和现实世界的数据,所提出的方法优于现有的技术,在有限的设置,它们是可用的,并扩展适用性到新的设置。

英文摘要:

In this paper, we introduce the first method that (1) can complete kernel matrices with completely missing rows and columns as opposed to individual missing kernel values, (2) does not require any of the kernels to be complete a priori, and (3) can tackle non-linear kernels. These aspects are necessary in practical applications such as integrating legacy data sets, learning under sensor failures and learning when measurements are costly for some of the views. The proposed approach predicts missing rows by modelling both within-view and between-view relationships among kernel values. We show, both on simulated data and real world data, that the proposed method outperforms existing techniques in the restricted settings where they are available, and extends applicability to new settings.
