摘要:

虽然用于学习多视图数据的表示的神经网络先前已经被提出作为最先进的多视图降维技术之一,但是如何仅用少量的标记数据使表示具有区分性还没有得到很好的研究。本文提出了一种半监督的神经网络模型,称为多视图判别神经网络(MDNN)。MDNN通过使用多个耦合的深度网络将样本投影到公共特征空间来找到非线性视图特定映射。它能够利用标记和未标记的数据来投影多视图数据,以便将来自不同类别的样本分离,并将来自同一类别的样本聚类在一起。它还使用视图之间的视图间相关性来利用标记和未标记数据中的可用信息。在四个数据集上进行的实验证明了该算法在多视图半监督学习中的有效性。

英文摘要:

While neural networks for learning representation of multi-view data have been previously proposed as one of the state-of-the-art multi-view dimension reduction techniques, how to make the representation discriminative with only a small amount of labeled data is not well-studied. We introduce a semi-supervised neural network model, named Multi-view Discriminative Neural Network (MDNN), for multi-view problems. MDNN finds nonlinear view-specific mappings by projecting samples to a common feature space using multiple coupled deep networks. It is capable of leveraging both labeled and unlabeled data to project multi-view data so that samples from different classes are separated and those from the same class are clustered together. It also uses the inter-view correlation between views to exploit the available information in both the labeled and unlabeled data. Extensive experiments conducted on four datasets demonstrate the effectiveness of the proposed algorithm for multi-view semi-supervised learning.
