MATLAB: I cant repeat nntool result

Deep Learning Toolboxneural network tool

I wanted to use codes to repeat it. All the parameters are the same and I copied all the weights from nntool to the generated m file. However, it can not give me accurate target results as nntool gave to me.

  • Frequently, the reason why two supposedly equivalent trainings don't yield the same result is because the initial state of the random number generator is not the same.
    Frequently, the reason why testing of two supposedly equivalent nets doesn't yield the same result is because the input data normalization and output data denormalization are not the same.
    Hope this helps.
