GEKPLS Extra Points? #216

Open khoopes opened 4 years ago

khoopes commented 4 years ago

What are extra points in the context of GEKPLS? The documentation simply says "Number of extra points per training point" What is an extra point and when should I enable them?

Thanks,

Kevin

You will find some answers in the paper (the link is broken in the SMT documentation).

extra_points is the number of additional nearby points that are sampled to make a first order Taylor approximation.

when should I enable them? The power of GEKPLS lies in using these extra points to improve predictions. So always adding a few extra points is good.
