Web15 aug. 2012 · Kohonen maps and Counterpropagation Neural Networks are two of the most popular learning strategies based on Artificial Neural Networks. Kohonen Maps (or Self Organizing Maps) are basically self-organizing systems which are capable to solve the unsupervised rather than the supervised problems, while Counterpropagation … Web18 jul. 2024 · Training a self-organizing map occurs in several steps: 1. Initialize the weights for each node. The weights are set to small standardized random values. 2. Choose a vector at random from the training set and present to the lattice. 3. Examine every node to calculate which one’s weight is most like the input vector.
