我实际上如何处理自组织 Map 的获胜神经元?

[英]What do I actually Do with the winning neuron of a Self Organizing Map?

I've reviewed weeks worth of material and everyone stops at identifying the winning neuron and plotting the SOM.我已经回顾了数周的材料,每个人都停下来确定获胜的神经元并绘制 SOM。

However, how do I actually use this output?但是,我该如何实际使用这个 output?

Unsupervised SOMs are mainly used for clustering and visualization.无监督 SOM 主要用于聚类和可视化。

Clustering: Find datapoints which have their winning neuron close to each other.聚类:查找获胜神经元彼此靠近的数据点。 These datapoints share similarities and might belong to the same cluster or class.这些数据点有相似之处,可能属于同一个集群或 class。

Visualization: Plot the SOM grid and try to include the information about the winning neuron per datapoint into it.可视化: Plot SOM 网格并尝试将有关每个数据点的获胜神经元的信息包含在其中。 Examples are the World Poverty Map , RGB clustering, and this blobs example .示例是World Poverty Map 、RGB 聚类和这个blob 示例
