Author problem with sim (neural network)
Seba

2005-11-26, 7:01 pm

Hi all I have got small problem. I am trying to learn neural networks
using Matlab as tool.
In my exercise I using 1 layer networks with delays. I try to use it
as adaptive filter. So I teaching it using "train" (teaching with
supervisor). After it I receive vector and in it there are many
thinks like: training ratio, outputs, errors etc. And here is my
problem my network receive different value in this vector and
different when I will use function sim. In this both situation input
is the same of course.

Maybe it won't be hard problem but always output is the same as input
although the network have been learned.

For me it seems as some kind of bug but it is more probably that I do
something wrong.

Did someone meet this or similar problem?!

Thanks for each advice.

Sincerely Seba
