显示 更早的评论
Hi everyone, first plis excuseme if I make mistakes, I don't speak english very well.
I have a problem, i am trying make a neuronal network for forescasting, and i am using a feed-forward. This net have 2 time-delay (t-1 and t-2), so if i need train my net and make my files of inputs and outpus, for exmaple for my file of input a make this:
x1 0 0 3
(x1-1) 0 3 2
(x1-2) 3 2 4
y1 0 0 6
(y1-1) 0 6 3
(y1-2) 6 3 12
You can see i have 2 type of date, the date x1 and y1, but i am using 4 delay,2 for x1 (x1-1, x1-2) and 2 for y1 (y1-1,y2-2), my question is, with the feed-forward time-delay, i dont need make that matris?, because when i try to make a feed-forward time-delay I have a new parametrer (INPUT DELAY VECTOR) and i am not sure how use that, if a make feed-forward time-delay how make the file of input? this way?
x1 3 2 4
y1 6 3 12
I did understand ?, Can you help me a example when the people use feed-forward time-delay or a manual? or something? thanks for all.

You can find additional info and examples searching both the Newsgroup and Answers using the two single search words:

The key to making the process relatively easy is to understand how to use the function PREPARETS. Start with the explanations and examples in the documentation:
help preparets
doc preparets
Hope this helps.
Thank you for formally accepting my answer.
