MATLAB_FFT

应用KNN算法解决0到9的手写数字识别问题，效果在90 以上，内部有两个数据集，一个为训练集（7291个数据），一个为测试数据（2791个数据），程序采用MATLAB编写，另附有文档，程序简洁易懂(Application KNN algorithm to solve 0-9 handwritten digit recognition problem, the effect is more than 90 , the inside has two data sets, one for the training set (7291 data), a test data (2791 data), the program written using MATLAB , attached a document, the program is simple and easy to understand)

说明：  带约束算子的粒子群算法，用于matlab环境，对于搞研究的教师有很大帮助(Operator Constrained Particle Swarm Optimization for the matlab environment, engage in research for teachers are very helpful.)

用最小平方反褶积算法来用c语言编程完成算法，解决反褶积问题(Deconvolution using least-squares algorithm to complete the algorithm with c language programming to address the problem of deconvolution)

及于核函数的维纳滤波，希望大家共同学习进步。程序我这里好用，也许你下载后需要调试，祝好(kwiener，，)

辨识所使用的数据长度保持不变，每增加一个新数据就抛掉一个老数据，使参数估计值始终只依赖于有限个新数据所提供的新消息，克服了遗忘因子法不管多老的数据都在起作用的缺点，因此该算法更能有效的克服数据饱和现象。(Identify the use of data length remain the same, every time you add a new data will throw away an old data, make the parameter estimate always depends on just co., LTD., a new data provided by the new news, overcome the forgetting factor method no matter how old data are in action shortcomings, so the algorithm can effectively overcome the more data saturation phenomenon.)

自己写的JS程序： 具体是使用JS+JQ+animate动画+勾股定理实现了画太极图，原理很简单，就是使用绝对定位作为 div坐标+动画+div生成，升级画法：可以使用三角函数(sin,cos,tan etc)，使用勾股定理每个像 素点的位置不太好把握！ 最后：感兴趣的同学可以将imgs中的图片改成透明的图片，替换JS中方块，这样效果好看些。(JS write their own programs: Specifically using JS+ JQ+ animate animation+ Pythagorean realized painting of Tai Chi, the principle is very simple, is to use absolute positioning as + animation+ div div coordinate generation, upgrade painting: You can use trigonometric functions (sin, cos, tan etc), each pixel using the Pythagorean theorem Prime location is not very good grasp of the point! Finally: Interested students can imgs pictures into a transparent image, replace JS in the box, so the effect look better.)
