An Analog CMOS Implementation of a Kohonen Network with Learning Capability

  • Chapter
VLSI for Neural Networks and Artificial Intelligence

Abstract

Kohonen (1988) introduced a new type of neural network that exhibits very interesting pattern classification and clustering properties. So far, they have been successfully used to solve various problems in fields like image processing or robot control. Unfortunately, although the task each cell has to accomplish is rather simple, computing time of software simulations becomes prohibitive as the size of a network increases. For real-time applications, parallel processing is required. Analog circuits are believed to allow potentially highest density of integration, and highest speed. However, since density is essential, only poor accuracy may be achieved. It is therefore necessary to select architectures that guarantee proper behaviour of the network despite of all error sources that may affect it.
