中文说明：稀疏自编码可以实现模式识别，进行提取数据之间的特征，通过训练得到特征参数。本代码通过举例实现图片特征的识别并重构出新的特征，通过重构误差来判别识别效果。
English Description：
Sparse coding pattern recognition can be achieved, to extract data for the characteristic, parameters are obtained by training. Code examples implement the pictures feature recognition and restructure a new feature, by reconstructing the errors to determine the result.
