WebA Self-Organizing Map (SOM) [KSH2001], also called Kohonen map, is a type of artificial neural network that is trained using unsupervised learning to produce a low-dimensional, discretized representation of the input space, called a map. SOM can be used as a clustering algorithm as well as a dimensionality reduction method. WebSep 28, 2024 · The example below of a SOM comes from a paper discussing an amazingly interesting application of self-organizing maps in astronomy. The example shows a complex data set consisting of a massive amount of columns and dimensions and demonstrates how that data set's dimensionality can be reduced.
