polynomial order of training equation of Artificial neural network

I have train and validate a 8-8-1 model from ANN toolbox.

But, any one can tell me that what is the order of the polynomial which was used in ANN training.

my data is more similar to these work

Answer 1

Hi,

Since it is neural network the system of equation will turn out to be linear only (if there is no nonlinearity like tanh or sigmoid). So, the order of polynomial is 1 in this case. From the similar question that is mentioned in above question you may see that relationship between y and x remains linear and its only weight multiplication that is happening.

Hope it clarifies.

Dear Raunak,

Thank you for your statment, if it is linear definitely it will a polynomial order of 1.
