说明：  一个用python实现的PCA算法，并且给了简易素材(A PCA algorithm implemented in python, and gave a simple material)

说明：  rbm受限玻尔兹曼机的python代码，总共有5种写法，总有一款适合你(Restricted Boltzmann machine python code,5 files in total, which can be run)

说明：  基于BP神经网络的手写数字识别系统，程序使用python语言编写，训练数据集为mnist；交互界面使用PYQT编写，用户可在画板通过鼠标书写数字作为识别对象。(The program of handwritten digit recognition system based on BP neural network is written in Python language, and the training data set is MNIST; the interactive interface is written in pyqt, and the user can write the digit on the drawing board through the mouse as the recognition object.)

爬取百度贴吧图片，可以帮助你了解爬虫的相关功能模块等(Crawl Baidu Post Bar picture)

说明：  使用pegasos算法进行minsit数据集分类(As mentioned above, Pegasos performs stochastic gradient descent on the primal objective Eq. (1) with a carefully chosen stepsize. We describe in this section the core of the Pegasos procedure in detail and provide pseudo-code. We also present a few variants of the basic algorithm and discuss few implementation issues.)
