摘要:

在许多机器学习问题中,标记的训练数据是有限的,而未标记的数据是充足的。其中一些问题的实例可以分解为多个视图,每个视图几乎都足以确定正确的标签。在本文中,我们提出了一个新的算法,概率多视图学习,使用的想法,随机协议之间的意见作为正则化。我们的算法适用于结构化和非结构化的问题,很容易推广到部分协议的情况。对于完全一致的情况下,我们的算法最大限度地减少每个视图的模型之间的巴塔查里亚距离,并表现得更好的几个平面和结构化的分类问题比CoBoosting和两视图感知器。

英文摘要:

In many machine learning problems, labeled training data is limited but unlabeled data is ample. Some of these problems have instances that can be factored into multiple views, each of which is nearly sufficent in determining the correct labels. In this paper we present a new algorithm for probabilistic multi-view learning which uses the idea of stochastic agreement between views as regularization. Our algorithm works on structured and unstructured problems and easily generalizes to partial agreement scenarios. For the full agreement case, our algorithm minimizes the Bhattacharyya distance between the models of each view, and performs better than CoBoosting and two-view Perceptron on several flat and structured classification problems.
