Spectrogram self-organizing map

A self-organizing map (SOM) or self-organizing feature map (SOFM) is an unsupervised machine learning technique used to produce a low-dimensional (typically two-dimensional) representation of a higher dimensional data set while preserving the topological structure of the data. For example, a data set with variables measured in observations could be represented as clusters of o… WebJun 15, 2016 · On the basis of these natural spectra, we construct a synthetic spectrogram with a spectrum every 15 min that consists of the following components: 1. Background (24 h). 2. Phase I (4 h). 3. Linear transition in time at each frequency from Phase I to background (4 h). 4. Linear transition in time at each frequency from background to Phase II (4 h).

WebSetting up a Self Organizing Map The principal goal of an SOM is to transform an incoming signal pattern of arbitrary dimension into a one or two dimensional discrete map, and to perform this transformation adaptively in a topologically ordered fashion. We therefore set up our SOM by placing neurons at the nodes of a one or two dimensional lattice.
