本工具箱提供了堆积有限Boltzmann机（RBMs）的深度信念网络（DBNs）的深度学习工具。
It provides deep learning tools of deepbelief networks (DBNs) of stacked restricted Boltzmann machines (RBMs).
它包括Bernoulli-BernoulliRBM、Gaussian-BernoulliRBM、无监督预训练的对比散度学习、稀疏约束、有监督训练的后向投影以及dropout技术。
It includes the Bernoulli-Bernoulli RBM,the Gaussian-Bernoulli RBM, the contrastive divergence learning forunsupervised pre-training, the sparse constraint, the back projection forsupervised training, and the dropout technique.
MNIST数据集的示例代码包含在MNIST文件夹中。
The sample codes with the MNIST dataset areincluded in the mnist folder.
详细说明请参阅MNIST文件夹中的readme.txt。
Please, see readme.txt in the mnist folder.
