[RBFOpt] RBFopt : question about noisy oracle definition

[NICOLAS Frederic]

Dear RBFOpt support team,

I have been using RBFOpt for a few days and I have a question about the definition of the noisy oracle.

In my case, I have defined my simulator (which is exact and slow to execute) as the one that is called through an implementation in the obj_funct that is given as a parameter of the RbfoptUserBlackBox function.
On the other hand, I have a database of variants for which I already have the results (delivered earlier by my simulator) and I would like to build a surrogate model of these results to serve as the noisy oracle that I intend to implement as the obj_funct_noisy as the last parameter of the RbfoptUserBlackBox function.

I was wandering whether I could build this surrogate model with some RBFOpt existing function (that returns the 3 awaited values) or if I should use an external library to this purpose, like scikit-learn for instance.
Would you bring me a piece of advice on this ?

Thank you for your kind support.

Cordialement, Regards,

Frédéric NICOLAS
