Kohonen Neural Network

Introduction

The Kohonen Neural Network (KNN) also known as self organizing maps is a type of unsupervised artificial neural network. This network can be used for clustering analysis and visualization of high-dimension data.

It involves ordered mapping where input data are set on a grid, usually 2 dimensional. It reduces dimensionality of inputs by mapping its input to a simpler version of itself while preserving its underlying structure. The key characteristic of KNN is that its self organizing...
