Setting weight and bias values in custom neural network

Hi all,

How to set value for weights and biases in a custom neural network?

Say: net=network;

net.numInputs=2;

net.inputs{1}.size=2;

net.inputs{2}.size=1;

net.numLayers=2;

net.layers{1}.size=1;

net.layers{2}.size=1;

net.inputConnect(1)=1;

net.inputConnect(1,2)=1;

net.layerConnect(2,1)=1;

net.biasConnect(1)=1;

net.biasConnect(2)=1;

net.biases{1}.learnFcn='learngdm';

net.biases{1}.initFcn='initzero';

net.biases{2}.learnFcn='learngdm';

net.biases{2}.initFcn='initzero';

net.outputConnect(2)=1;

net.layers{1}.transferFcn='tansig';

net.layers{2}.transferFcn = 'purelin';

net.inputweights{1}.initFcn='initzero';

net.inputweights{1}.learnFcn='learngdm';

net.inputweights{2}.initFcn='initzero';

net.inputweights{2}.learnFcn='learngdm';

now i want: bias on layer 1 =0.9; bias on layer 2 =0.7; input 1 weight = 1.1; input 2 weight = 0.9; layer 1 weight = 1.3; layer 2 weight = 1;

how should i configure it?

thanks you

You can use 'setwb' or 'separatewb' command. Refer link below:

Hope it helps!!!

Thank you. But i want to set individual value to weight and bias.
