Kohonen network, also known as self-organizing map (SOM), is a type of neural network that is widely used for unsupervised clustering. It is a two-layered network consisting of input layer and output layer. The output layer is a grid of nodes with each node representing a cluster. During training, the weights of the input layer are adjusted to minimize the distance between the input data and the closest node in the output layer. The nodes in the output layer are then grouped into clusters based on their similar weights. Kohonen network is known for its ability to preserve the topological structure of the input data, making it a popular choice for data visualization and exploratory data analysis.
