Network Structure and the I-O Map

Using the notation introduced above and Figure-#fig1#330>, given an input vector #tex2html_wrap_inline2631#, the input to the jth node of the hidden layer is:

#equation1584#

The output of the #tex2html_wrap_inline2635# hidden node is:

#equation1587#

Next, the input of the #tex2html_wrap_inline2637# node of the output layer is:

#equation1590#

and the output of this #tex2html_wrap_inline2639# output node is:

#equation1593#

The I-O mapping of the network is the function from #tex2html_wrap_inline2641# computed by the net.
