Self-organizing feature map neural network

WebMar 23, 1999 · Self-organizing maps (SOMs) are a data visualization technique invented by Professor Teuvo Kohonen which reduce the dimensions of data through the use of self-organizing neural networks. The problem that data visualization attempts to solve is that humans simply cannot visualize high dimensional Webneural models we use: two static models (the multi-layer perceptron and the multi-output-layer perceptron), a time-delay neural network, and a self-organizing feature map. The …
