Optimisation with neural network

Dear Sir

I have data x1,x2 and objective y this data is saved on excel sheet hwoever ; I am asking can i do optimisation by using Nueral network to generate surogate model and feed this model to optimation algorithem such as ga or fminicon. I have found some example in simulank MATLAB example for N.N and Ga but i think this optimisation to reduce the eror of predicted model.

regards

many thanks ; Would you please explain if it is possible to get the surrogate model by using Nueral network .

[Walter Roberson]

I do not know. I have not worked with surrogate models. Most formulas can be computed with a neural network that is sufficiently large and has enough layers, but neural networks cannot do iteration until a criteria is met. I do not know the math for surrogate models.

Please keep in mind the difference between "can be done" with a neural network, compared to "is a good idea to do" with neural networks.

I started with it is good idea to do and ihave done it as the MATLAB powerfull program . Thank you for your help.
