how to get the Hidden layer output???

Hi

 How to get the output of hidden layer in neural network.. I'm using 1 hidden layer and 1 o/p layer for image compression.. I'm in need of hidden layer output where image is compressed.. Help me pls..

Answer 1

[Greg Heath]

y = b2 + LW*h % PURELIN OUTPUT

h = LW\(y-b2) % Hidden Layer output

However, the solution is not unique if null(LW) is not empty.

Hope this helps

Thank you for formally accepting my answer

Can you please tell me what is h in first equation? and for transig should I use IW instead of LW?
