matlab实现球形自组织特征映射

收录时间:2021-12-01
资源分类:Matlab 工具:MATLAB 7 (R14)

球形自组织特征映射是一种用于数据聚类和可视化的当代技术。
它们提供的主要优势如下:
1.顺利训练
2.实现在任意维没有额外的计算成本。
3.任意维数据可视化
此工具箱包含一组函数和一个GUI,可用于从球形自组织特征映射(SOFM)创建图示符。它可自由分配用于教育和研究目的。

S-SOFM Toolbox

The Spherical Self-Organizing Feature Maps is a contemporary technique for data clustering and visualization.

 

The main advantages they offer are the following:

1. Smooth training

2. Implementation in arbitrary dimension without additional computational cost.

3. Data visualization in arbitrary dimensions

 

This toolbox contains a set of functions and a GUI which can be used to create glyphs from spherical Self-Organizing Feature Maps (SOFMs). It is freely distributable for educational and research purposes.

 

Example:

 

% loads the data to be visualized

load henon-1024-4.mat

 

%loads the S-SOFM structure

load c4-24.mat

 

%trains the S-SOFM

[w,g,r]=trainGlyph(P,X,C,0.5,20,'plot');

 

% plots the S-SOFM

glyph(X,r);
