part of the numerical algorithm c++, for some netizens should be very useful

遗传算法优化 BP 神经网络是用遗传算法来优化 BP 神经网络的初始权值和阈值,使优化后的 BP 神经网络能够更好地预测函数输出。遗传算法优化 BP 神经网络的要素包括种群初始化、适应度函数、选择操作、交叉操作和变异操作。

自己做的，像EXCEL中的数值递增，相当于26进制-do for myself, like Excel numerical increase, equivalent to 26 band

代码是blei03年经典paper主题模型的实现——LDA。代码在linux下运行，且LDA是目前主题模型的主流算法之一，是pLSI的进化版本，主要涉及贝叶斯公式、狄利克雷分布等概率知识，能从大量文本中自动提取出隐含在背后的语义主题。

集成ifft和fft，以头文件的形式提供调用，可以用于任何C编译器-integration and fft to the first document in the form of call, can be used on any C compiler

一种用C语言实现的快速傅立叶变换和傅立叶反变换,经测试十分好用-A C-realize the fast Fourier transform and Fourier inverse transform, have been tested and is very easy to use

应用背景本代码用于国际机器人比赛，识别图标有左拐、右拐、直走三个方向，识别率可以达到90%，在机器人倾斜角度相对较小的情况下，识别率可以达到100%。每秒钟可以识别40~60张图片。有效的提升了机器人竞技实力！关键技术本代码采用图像细化骨架提取和霍夫变换拟合直线，通过图像细化提取路标的骨架，再通过霍夫变换拟合直线，再通过拟合的直线，计算拟合后直线的方向，以45度为标准，倾角大于45度的视为纵线，否则视为横线，在通过判定的直线方向给拟合后直线归类，竖直和水平方向，根据直线中心点的位置，判断当先路标的指向。

可以把一图形的投影中心线找出来,我本科论文就做过那玩意-A graph can find out the centerline of the projector, I did undergraduate thesis on那玩意

该程序包括了一个应用最为广的离散傅里叶变换，褶积，抽样最小相位。绝对能运行-The program includes an application of the most widely used discrete Fourier transform, convolution, sampling minimum phase. They can certainly run
