Concerns about "Edit Shallow Neural Network Properties"

Hi everyone,

This is my first attempt with neural network on Matlab and there is one thing I don't fully understand.

Under "Weight and Bias Values," I read the following statement:

Each input weight net.IW{i,j} has as many columns as the size of the jth input (net.inputs{j}.size) multiplied by the number of its delay values (length(net.inputWeights{i,j}.delays)).

Since I simply want to create a simple feedforward neural network (I know that I can use feedforwardnet function but I would like to try a custom one), I won't need any delays in the weights. According to the above statement and my matlab code, the net.IW{i,j} = [ ].

How would I initialize non-empty weights for my network?

Thanks
