：在有限区域内分布的稀疏不均的、具有一定分布结构的海量数据集的高效、高精度聚 类问题是一个尚未完全圆满解决的难题。针对Affinity Propagation 聚类算法(AP)的不足之处， 提出了两个改进型的聚类算法(n limited areas of uneven distribution of sparse, has certain distribution structure of the mass datasets of high efficiency, high precision together Problem is a perfectly solved problem has not yet completely. For Affinity Propagation clustering algorithm (AP) of the deficiencies, Put forward the two improved version of the clustering algorithm)

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)

for signal processing

It is an Gauss_saidel method programed in Matlab. The effectiveness is tested by one benchmark function.

In computer science and information theory, Huffman coding is an entropy encoding algorithm used for lossless data compression. The term refers to the use of a variable-length code table for encoding a source symbol (such as a character in a file) where the variable-length code table has been derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol. It was developed by David A. Huffman while he was a Ph.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".

MATLAB编写的ARMA建模程序，可实现UI打开EXCEL文件，自动选取合适滞后阶数ARMA建模和任意几期预测。(ARMA modeling program written in MATLAB, enabling the UI Open EXCEL file and automatically selects the appropriate number of lags several of ARMA modeling and forecasting arbitrary.)

说明：  时间序列的人口预测，采用三次指数平滑，还有灰色预测，有数据提供参考。(The population forecast of time series adopts three exponential smoothing and grey forecast, which provides reference for data.)

信号频谱分析的MATLAB实现程序 内附多个源代码，可作学习参考(Analysis of the signal spectrum to achieve the MATLAB program containing a number of source code, reference can be used for learning)
