MQAM在DSP中进行信号处理需要的载波相位恢复程序，适用于16QAM信号的载波相位恢复，利用Python语言编写 (MQAM signal processing in the DSP requires the carrier phase recovery process, the 16QAM signal applied to the carrier phase recovery, using the Python language)

说明：  这是Python关于机器学习经典实例第12章的代码，，，可视化数据(This is the Python code for Chapter 12 of the classic machine learning example, ,, Visualization data.)

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)

说明：  实现了贪吃蛇小游戏功能，没有使用pygame模块(Realize the function of greedy Snake game)

Python DHCP client source code

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

说明：  使用协同过滤的推荐系统测试代码Predicting movie ratings using collaborative filtering and latent concept extractors based on matrix decomposition methods like SVD and CUR on the movielens-100k dataset The project explores techniques for predicting unknown user ratings based on a large dataset of users and movie ratings.(Recommender-SystemsWe used 6 different recommender methods to predict user ratings across the data sets. Namely we set up Collaborative Filtering along with its baseline variant and Matrix decomposition techniques like Singular Value Decomposition and CUR. Moreover, we also implemented dimensionality reduction in these matrix decomposition techniques which preserved 90% of the energy so as to increase the computational efficiency while keeping the accuracy similar for these methods.)
