WebMar 24, 2024 · The self-organizing layer is composed of some numbers of 2D maps, with each map focusing on modelling a local sub-region of the input space. The algorithm is applied in few steps (modeling space, data space). The first … WebAs in one-dimensional problems, this self-organizing map will learn to represent different regions of the input space where input vectors occur. Concepts Cluster with Self-Organizing Map Neural Network Use self-organizing feature maps (SOFM) to classify input vectors according to how they are grouped in the input space.

WebMay 1, 2024 · Self-organization is a process described as follows. A vector from the data space ( X) is presented to the network. The node with the closest weight vector W j is the winner neuron or best matching unit (BMU). This is calculated using a simple discriminant function (Euclidean distance) and a “winner-takes-all” mechanism (competition). WebAbout : A self-organizing map (SOM) or self-organizing feature map (SOFM) is a type of artificial neural network that is trained using unsupervised learning to produce a low …
WebProperties of the Feature Map Once the SOM algorithm has converged, the feature map displays important statistical characteristics of the input space. Given an input vector x, the feature map Φ provides a winning neuron I(x) in the output space, and the weight vector wI(x) provides the coordinates of the image of that neuron in the input space.
