Is it possible to run a NARX neural network with less than 10 timesteps?

Hi,

I have four input variables and one target variable for each year from 2011 to 2019, which gives me 9 timesteps. I then want to predict a value for 2020 using a NARX neural network. However, I cannot create the network because I get a "Data has less than 10 timesteps." warning. Is it possible to create a NARX NN with 9 timesteps?

Thanks,

James

If you are creating nerual network from nnstart then you would require atleast 10 timesteps.

Alternatively if you can follow the example Train NARX Network and Predict on New Data & write a MATLAB script as below then I think you can create and train the network.

[X,T] = simpleseries_dataset;
Xnew = X(10:100);
X = X(1:9);
T = T(1:9);

net = narxnet(1:2,1:2,10);
[Xs,Xi,Ai,Ts] = preparets(net,X,{},T);
net = train(net,Xs,Ts,Xi,Ai);
view(net)
