Hello everyone, I am new to OT and I would like to make a polynomial approximation of an expensive function. For that I would like first to evaluate the function at the colocation points and then train my polynomial. In the example in OT, those two steps are not separated. However is there a way to run them separately ? Alternatively, assuming I already have the training set (colocation points and the corresponding function value) is it possible to train the polynomial with OT winthout having OT to evaluate the expensive function (with the function FunctionalChaosAlgorithm.run()) ?
Thanks a lot Francois Sanson
