Self-Organizing Maps

• Invented by Tuevo Kohonen
  • Often called "Kohonen map" or "Kohonen network"
  • Kohonen is the most cited scientist from Finland
• Supervised vs. Unsupervised learning
  • The Perceptron (both single-layer and multi-layer) is a supervised learning algorithm. Each training example requires a label.
  • The Self-Organizing Map is an unsupervised learning algorithm. The training examples do not require labels.
