灰色数据融合预测算法与灰色关联度调试代码

MIT的EECS学院本科新生入学第一门课程introduction_to_cs&programming的作业答案，也是学习python语言和计算机科学很好的资料。(Institute of MIT' s EECS undergraduate admission first course introduction_to_cs & programming operating the answer is to learn good python language and computer science information.)

本代码为多智能体系统的一段MATLAB仿真源文件，希望大家学习。(This code for agent system of a MATLAB simulation source file, hope everybody to learn.)

说明：  海浪p-m谱模拟及海浪二维模拟，可以正确模拟出海浪的p-m谱及海浪(The p-m spectrum simulation of sea waves and the two dimensional simulation of sea waves can correctly simulate the p-m spectrum and wave of sea waves)

采用帧差法的运动目标检测,采用 matlab来实现，算法中包含图像处理的基本手段，并含有形态学处理，膨胀，消除，还有边缘检测canny算子

说明：  texture feature extraction using matlab

编写了一个pso优化bp神经网络的程序，应用在分类中。第一步：pso优化bp神经网络得到最优的阈值和权值，第二步bp神经网络把该最优的阈值和权值作为初始阈值和权值，采用动量及自适应学习速率算法进行训练。附件中，是数据和编写的部分程序，tiqushuju是用来提取文本中的数据构造样本集的函数。mubiao是用来构造期望输出的函数。bp是已经编写好的，未使用pso优化的bp神经网络函数。pso是本人编写的pso优化bp神经网络的函数，psobp是采用pso优化的阈值和权值作为bp神经网络的初始权值和阈值进行训练和测试的函数。但是本人编写的粒子群优化bp网络的程序训练效果和测试效果远不如只使用bp的效果。(Prepared a pso bp neural network optimization, application in the classification. First step: PSO optimization bp neural network to get the optimal threshold and weight, the second step bp neural network to the optimal threshold and weight as the initial threshold value and weight, momentum and adaptive learning rate training algorithm . Accessories, data and written part of the program,. Tiqushuju function is used to extract the text data structure of the sample set. mubiao is used to construct the desired output function. BP is already written, unused PSO optimization bp neural network function. pso pso bp neural network optimization function is written in my psobp PSO optimization threshold and the right values ​ ​ as a function of the initial weights and thresholds of BP neural network training and testing. But I am prepared particle swarm optimization BP network training effect and test the effect is far better than using only the effect of the bp.)
