how can I access the outputs of the hidden layers in a neural network?

조회 수: 9 (최근 30일)
I have a 2 hidden layer network. I trained it using a set of input output data but after training I want to access the outputs of the hidden layers for applying SVD on the hidden layer output. Please let me know how can I do it.
Thank You.

is there any way to access the outputs of hidden layers with this? net.outputs{i}.processParams

Take the I-H-O net and create an I-H net with no hidden layer.
See the section in the documentation on custom nets.
ADDITION:
Or, you can just write the code. If there is no normalization
IW = cell2mat(net.IW); b1 = cell2mat(net.b{1});
h = tansig( IW*x + repmat( b1,H,N ) );
Hope this helps.
Thank you for formally accepting my answer.
