数据挖掘-实用机器学习技术（中文第二版）

从猎聘网爬取相关招聘信息和评论信息，网络爬虫(又被称为网页蜘蛛，网络机器人，在FOAF社区中间，更经常的称为网页追逐者)，是一种按照一定的规则，自动的抓取万维网信息的程序或者脚本。(From the recruitment network crawling relevant recruitment information.Web crawlers, also known as web spiders, web robots, more commonly known as web chasers in the FOAF community, are programs or scripts that automatically crawl the World Wide Web in accordance with certain rules.)

说明：  使用python基于numpy编写函数和程序，完整实现了SC-FDE链路的仿真，包括调制、成型滤波、信道、同步、频偏补偿、均衡、解调。(Full realization of SC-FDE link simulation using python with functions based on numpy.)

该代码实现将基本的地图匹配功能,讲GPS获取到的数据与路网匹配，并将偏移道路的数据拉回道路上(this python code complet function that map matching)

说明：  这是用python语言编写的bp神经网络算法，用来评估算法的正交验证得分和平均准确率(This is a BP neural network algorithm written in Python language, which is used to evaluate the orthogonal verification score and average accuracy of the algorithm)

说明：  用tensorflow实现vgg深度学习网络(Realization of VGg deep learning network with tensorflow)

说明：  python实现实时视频流传输和显示，从客户端到服务器端(Python implements real-time video streaming transmission and display from client to server)

Stock：自定义的随机股票交易回测系统(Stock: a custom random stock trading back test system)

亚声速-超声速等熵喷管流动的CFD解法，运用python语言对方程的求解实现。(CFD solution for the flow of subsonic and supersonic isentropic nozzle,the solution of the equation is realized by using the python language.)

说明：  Pywavelets的cwt函数做连续1维小波变换的时频分析，并图形显示(Time and Frequency of Continuous 1-D Wavelet Transform and Graphic Display)

使用pyqt 实现windows下串口通信，包括串口选择配置，数据收发等。当然也可以加入pygraph实现波形显示，可做为上位机程序的参考(Using pyqt to achieve windows serial communication, including serial selection, configuration, data transceiver. Of course, you can also join the pygraph to achieve waveform display, can be used as a reference to the host computer program)
