这种竞争可以通过在神经元之间具有横向抑制连接(负反馈路径)来实现。其结果是神经元被迫对自身进行重新组合,这样的网络我们称之为自组织映射(Self Organizing Map,SOM)。 拓扑映射 神经生物学研究表明,不同的感觉输入(运动,视觉,听觉等)以有序的方式映射到大脑皮层的相应区域。 这种映射我们称之为拓扑映射,它具有两...

A Self-Organizing Map (SOM) is a type of Artificial Neural Network (ANN) that organizes different types of input data into clusters based on their similarities and differences. It is trained using an unsupervised learning method and can be used for energy management by focusing on the difference...
本部分代码内容参考自GitHub - Shashank-Iyengar/Self-Organizing-Maps: Shaft health assessment using SOM and SOM-MQE。 1. SOM 1.1 简介 这个算法感觉已经没啥改进空间了(SOM的知识在知乎中少的可怜),就和KNN一样,但作为一般的工业应用还是没有问题的(横向课题)。
Self Organizing Map 自组织映射Self Organizing Map (SOM)属于无监督学习(Unsupervised Learning)神经网络的一类,一般用于特征识别。简单来说,SOM就是把一系列高维数据集映射成低维的离散数据集(通常是二维或者一维),而映射后的数据集通常会以拓扑图的形式表示,常见的比如n*n的网格/坐标图,每个cell或node代表一类数据...
In this work an online algorithm is presented for the construction of the self-organizing map (SOM) of symbol strings. Each node of the SOM grid is associated with a model string which is a variable–vector sequence. Smooth interpolation method is applied in the training which performs simultan...
A self-organizing map is defined as a one-dimensional layer of 10 neurons. This map is to be trained on these input vectors shown above. Originally these neurons are at the center of the figure. Of course, because all the weight vectors start in the middle of the input vector space, al...
