一个五子棋游戏，用阿尔法贝塔剪枝的方法实现博弈树，程序会根据最优情况选择正确的落子位置(A Gobang game, using Alphabeta pruning method to achieve the game tree, the program will choose the right drop position according to the optimal situation.)

RNN神经网络的应用和概念，RNN源代码和使用方法(You can find that the parameters `(W, U, V)` are shared in different time steps. And the output in each time step can be**softmax**. So you can use**cross entropy** loss as an error function and use some optimizing method (e.g. gradient descent) to calculate the optimized parameters `(W, U, V)`. Let recap the equations of our RNN: )

说明：  回声状态网络(ESN)python实现代码，ESN是RNN的改进(Echo State Network (ESN) Python implementation code, ESN is an improvement of RNN)

RNN时序预测(RNN series predict)

说明：  本文件为《简明Python教程》中的部分代码及重要备注，可方便入门Python的新手学习(This file is part of the code and important notes in the Concise Python Tutorial. It is easy to get started with Python.)

讲解Python的基本使用方法，包括数据结构，生成器，迭代器和网络编程(Explain the basic usage of Python)

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)
