量子遗传算法

说明：  python 调用 cad 随机骨料模型(Python calls CAD random aggregate model)

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.)

说明：  该资源为应用GNUradio工具，对USRP的开发，主要实现了频谱感知，以及根据频谱感知的结果进行ofdm通信的功能(This resource is the development of USRP using gnuradio tool. It mainly realizes the function of spectrum sensing and OFDM communication according to the result of spectrum sensing)

用python语言处理windows office 办公软件excel表格数据(Processing windows office software excel table data in python language)

说明：  对现存的主流分词方法进行了分析和比较，对前人的成果和经验进行了研究和改进,设计实现了一个基于词典和统计方法的在线中文分词系统。本文系统使用了基于一种主流分词方法的经典算法,双向最大匹配法。这种方法能够将正向最大匹配法得到的分词结果和逆向最大匹配法得到的结果进行比较，从而决定正确的分词方法。这类算法的优点是速度快，时间复杂度为O（n），实现简单。本系统为用户提供了一个中文分词的在线平台，有文本分词，输入分词内容，实时显示分词结果等功能可供使用，本系统在切词准确度和速度上的表现较为良好,基本完成了中文分词的工作,提供了较好的用户体验。本文系统的创新点在于，将python语言作为开发语言，并选择了较为热门的web框架Flask作为开发在线系统的框架，实现了一个在线中文分词系统。目的是方便用户进行分词，并实时观测结果。(This paper analyzes and compares the existing mainstream word segmentation methods, studies and improves the previous achievements and experiences, and designs and implements an online Chinese word segmentation system based on dictionary and statistical methods. In this paper, a classical algorithm based on a mainstream word segmentation method, bi-directional maximum matching method, is used. This method can compare the result of forward maximum matching method with that of reverse maximum matching method, so as to determine the correct segmentation method. This kind of algorithm has the advantages of high speed, O (n) time complexity and simple implementation.)

利用数据，进行对出行者出行状态的蒙特卡洛模拟方法(metro Carlo simulation)

说明：  以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

说明：  tensorflow代码，适合初学者入门(Tensorflow code, suitable for beginners)

说明：  这是强化学习关于动态规划的例子，我们需要让智能体自己找到最好的策略。环境是一个5*5的格子，只有走到正确的格子下才能够获得奖励。通过这个例子对动态规划能有一个很好的了解。(This is an example of reinforcement learning about dynamic programming. We need to let agents find the best strategy for themselves. The environment is a 5*5 grid. Only when you get to the right grid can you get a reward. Through this example, we can have a good understanding of dynamic programming.)
