Intro to Self Organizing Map and Self Organizing Map Python …

WebSelf-organizing maps. A SOM is a technique to generate topological representations of data in reduced dimensions. It is one of a number of techniques with such applications, with a better-known alternative being PCA. However, SOMs present unique opportunities, both as dimensionality reduction techniques and as a visualization format. WebA Python Library for Self Organizing Map (SOM) The library implement fast online training. The implementation of the algorithm is carefully done through matrix calculations, such as scipy sparse matrix and numexpr for calculation of Euclidean distance.
