Bernard Widrow carried out the pioneering research for neural networks at Stanford University in the 1950s. It is a technology that requires massive computer capacity and, therefore, practical applications using this technology have been limited. However, it is a fascinating technology--imagine computers that function the way scientists think the brain functions! An Introduction to Neural Networks by Leslie Smith at www.cs.stir.ac.uk/~lss/NNIntro/InvSlides.html is a good place to begin exploring this technology. Next, check out The Neural Net Tutorial at www.ifsys.co.uk/html/tutorial.html. (The Neural Network Tutorial at ourworld.compuserve.com/homepages/ITechnologies/tutorial.htm is not currently available.)
