Hi, everyone!
I am a little bit confused how to use a time delay neural network for multistep ahead prediction.
By my system characteristics, I must use a time delay neural network and not others. So, from previous measurement, I know the input and target time series, where:
Xdata(1:500) (input)Tdata(1:500) (target)
Let's create the neural network:
net = timedelaynet(1:10,10);[Xs,Xi,Ai,Ts] = preparets(net,Xdata,Tdata);net = train(net,Xs,Ts,Xi,Ai);
I can clearly understand all the procedure until this point. However, I do not know how to prepare the new input data to be predicted and to use the net. I mean, in the future, I will just know the input data. So, how I could predict it? For example:
Xnew1(1:50);Y1 = net(Xnew1,Xi,Ai);
Ans further, for a new data:
Xnew2(51:100); Y2 = net(Xnew2,Xi,Ai);
Would it be the same? With the same Xi and Ai?
Thanks for helping!
