I made an equation using a Artificial Neural Network (ANN) using MATLAB NN Toolbox for two input and one output.
While the test output (0.863) close to the experimental value (0.8646), the output from the equation shows completely different.
For your information, i was using the following equation format .
Output, Y = LW (x) +b2
The hyperbolic tangent function x = exp(a)-exp(-a)/(exp(a)+exp(-a) ) where a = ∑{(IW∗Input)+b1}.
any advice and suggestions will be greatly appreciated
Thanks in advance.
