Improvement of Convective/Severe Weather Prediction:
Strategy: Objective 1 (SOMs)
• Kohonen (1995)
• Competitive neural network
• Unlike other techniques, classes are
related to each other in a 2-
dimensional matrix (feature map)
• If you remove the neighborhood
function, the SOM is reduced to a kmeans clustering technique (vectors
compared using Euclidean distance)

Public domain software: SOM_PAK
