中文简介:
介绍了一种训练受限玻尔兹曼机器的新算法。该算法名为Persistent Contrastive Divergence,与标准的Contrastive Divergence算法不同,它的目的是从几乎完全模型分布中抽取样本。通过学习图像和标签的联合分布模型,将其与一些标准的对比发散算法进行比较,分别对手写数字进行建模和对数字图像进行分类。持久对比发散算法优于其他对比发散算法,同样快速而简单。
课程简介: A new algorithm for training Restricted Boltzmann Machines is introduced. The algorithm, named Persistent Contrastive Divergence, is different from the standard Contrastive Divergence algorithms in that it aims to draw samples from almost exactly the model distribution. It is compared to some standard Contrastive Divergence algorithms on the tasks of modeling handwritten digits and classifying digit images by learning a model of the joint distribution of images and labels. The Persistent Contrastive Divergence algorithm outperforms other Contrastive Divergence algorithms, and is equally fast and simple.
关 键 词: 玻尔兹曼机器; 抽取样本; 对比发散算法
