BioinformaticsToolbox3.2
为用户提供了一个开放的、可扩展的环境,用于在药品研究、遗传工程和其他与基因组、蛋白质等相关的项目中进行原型算法的开发以及应用。(Bioinformatics Toolbox™ offers computational molecular biologists and other research scientists an open and extensible environment in which to explore ideas, prototype new algorithms, and build applications in drug research, genetic engineering, and other genomics and proteomics projects. This bioinformatics software provides access to genomic and proteomic data formats, analysis techniques, and specialized visualizations for genomic and proteomic sequence and microarray analysis. Most Bioinformatics Toolbox functions are implemented in the open MATLAB® language, enabling you to customize the algorithms or develop your own.)

NewK-means-clustering-algorithm
说明: 珍藏版,可实现,新K均值聚类算法,分为如下几个步骤:
一、初始化聚类中心
1、根据具体问题,凭经验从样本集中选出C个比较合适的样本作为初始聚类中心。
2、用前C个样本作为初始聚类中心。
3、将全部样本随机地分成C类,计算每类的样本均值,将样本均值作为初始聚类中心。
二、初始聚类
1、按就近原则将样本归入各聚类中心所代表的类中。
2、取一样本,将其归入与其最近的聚类中心的那一类中,重新计算样本均值,更新聚类中心。然后取下一样本,重复操作,直至所有样本归入相应类中。
三、判断聚类是否合理
采用误差平方和准则函数判断聚类是否合理,不合理则修改分类。循环进行判断、修改直至达到算法终止条件。(NewK-means clustering algorithm ,Divided into the following several steps:
A, initialize clustering center
1, according to the specific problems, from samples with experience selected C a more appropriate focus the sample as the initial clustering center.
2, with former C a sample as the initial clustering center.
3, will all samples randomly divided into C, calculate the sample mean, each the sample mean as the initial clustering center.
Second, initial clustering
1, according to the sample into the nearest principle clustering center represents the class.
2, as this, take the its recent as clustering center of that category, recount the sample mean, update clustering center. And then taking off, as this, repeated operation until all samples into the corresponding class.
Three, judge clustering is reasonable
Adopt error squares principles function cluster analysis.after clustering whether reasonable, no reasonable criterion revisio)
