R教程中的Kohonen SOM映射 [英] Kohonen SOM Maps in R Tutorial
问题描述
我只是在寻找一个好的教程，它将引导我逐步了解如何在R中创建SOM.我正在阅读Kohonen和Kaski的有关使用地图识别福利结构的论文，并想尝试这种技术.
I am simply looking for a good tutorial that will walk me through how to create a SOM in R. I am reading Kohonen and Kaski's paper on using the maps to identify the structure of Welfare, and want to try the technique my self.
我认为R中的许多示例有很多不足之处.我浏览了网上，却没有发现我认为使该过程易于理解的任何内容.
I think many of the examples in R have a lot to be desired. I have looked on the web and didn't find anything that I thought made the process easy to understand.
我们将不胜感激.
推荐答案
一些指针:
- SOM package
- Kohonen package
大多数与SOM相关的软件包都来自化学计量学和计算物理领域，但您还可以查看 CRAN上的群集视图
Most of the SOM related packages are from the Chemometrics and Computational Physics area, but you also have a look at the cluster view on CRAN.
顺便说一句，我不知道任何教程，但是找到示例的一种好方法此示例显示了如何与GGobi一起使用.
Incidentally, I'm not aware of any tutorials, but one good way to find examples is to google with ext:r. There are several "som" scripts that show up that way, including this example which shows how to use it with GGobi.
