Example 2 . Consider the 4 - Node architecture a = ( 2 , 2 ) ; it has a hidden layer
with 2 nodes , and an output layer with 2 nodes . Since there are two output
nodes , there are four possible output values : 00 , 01 , 10 and 11 . The first layer
For the training of the output layer , the training set also contained the desired
output function . ... 2-1 ( 11 ) This learning algorithm ensures that a given hidden unit will learn to ignore inputs which do not contribute to the unit's firing .
Each connection change depends only on the statistics which are collected in
parts I and II about the two units ... The simulation time on a VAX 11/750 for a learning cycle is approximately 6 min. ... The term "feedforward” implies that no
processing output can be an input for a processing element on the same layer or

Neural and Synergetic Computers deals with basic aspect of this rapidly developing field. Several contributions are devoted to the application of basic concepts of synergetics and dynamic systems theory to the constructionof neural computers. Further topics include statistical approaches to neural computers and their design (for example by sparse coding), perception motor control, and new types of spatial multistability in lasers.

preliminary training runs has been that for = 5 the network did not train properly (
runs 9-11 ) . ... With 1 = 2 ensuring slower learning the problem of excessive
