使用matlab编写的BP神经网络的算法，使用单隐层的网络，其中包括一个实例文件，对20个数据作分类。-Prepared using matlab algorithm BP neural network, using a single hidden layer networks, including an instance of the file, the data for 20 categories.

DBN代码 DBNs是一个概率生成模型，与传统的判别模型的神经网络相对，生成模型是建立一个观察数据和标签之间的联合分布。-DBN code DBNs generate a probability model, and determine the neural network model is relatively traditional, distributed generation model is to establish a joint observation data and tags.
