WebSep 19, 2024 · S elf-Organizing Map (SOM) is one of the common unsupervised neural network models. SOM has been widely used for clustering, dimension reduction, and feature detection. SOM was first introduced by Professor Kohonen. For this reason, SOM also called Kohonen Map. It has many real-world applications including machine state monitoring, … 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 … See more Self-organizing maps, like most artificial neural networks, operate in two modes: training and mapping. First, training uses an input data set (the "input space") to generate a lower-dimensional representation of … See more There are two ways to interpret a SOM. Because in the training phase weights of the whole neighborhood are moved in the same direction, … See more • The generative topographic map (GTM) is a potential alternative to SOMs. In the sense that a GTM explicitly requires a smooth and continuous mapping from the input space to the map space, it is topology preserving. However, in a practical sense, this … See more • Rustum, Rabee, Adebayo Adeloye, and Aurore Simala.
