Here a self-organizing feature map network identifies a winning neuroni* using the same procedure as employed by a competitive layer. However, instead of updating only the winning neuron, all neurons within a certain neighborhoodNi*(d) of the winning neuron are updated, using the Kohonen rule....

自组织映射(Self-Organizing Maps, SOM) 自组织映射(Self-Organizing Maps,SOM)作为一种神经网络模型的灵感来自大脑皮层映射的拓扑性质。我们的视觉输入、触觉输入和听觉输入均非直接输入给大脑,而是先以某种拓扑方式映射到神经网络,信息经过映射之后再传入到大脑中进行处理,比如 视觉:视网膜拓扑映射(视野中的位置)、方向...

Self-Organizing Feature Map Neural Networks (SOM) SOM是一种无监督学习的神经网络,先贴上最近写的一个利用SOM对图片进行压缩并恢复的简单应用,留个大坑:1.有空再来总结SOM的概念,学习过程,优化算法。2.把代码再用python和C++重新实现一遍作为编程练习。。。 训练过程大致如下: 将图片分解并形成输入向量X = {...

self-organizing map (SOM), also known as a Kohonen network, can be used to map high-dimensional data into a two-dimensional representation SOM根据输入的高维数据集在"结构相似性"上的共同点,映射到一个二维的坐标点集中,并在这个映射(降维)的过程中,保留原始数据集的拓朴结构,例如在高维空间中相邻的数...
2.1.6Self-organizing maps Self-organizing maps(Kohonen, 2001) are a special type of unsupervised artificial neural networks based on competitive learning: the output neurons compete with each other in training to be activated (Haykin, 2009). In a self-organizing map the neurons are located at ...
