Resampling Error Resampling_Error

Resampling_Error is designed to easily compute resampling error on design points

Resampling_Error

Format

An R6Class generator object

Details

Compute resampling error of a surrogate model

Methods

Resampling_Error$new()

Creates a new Resampling_Error

get_val(surrogate_model)

It evaluates the resampling error for a surrogate_model (object UPSM).

Examples

library(UP)
d              <- 2
X             <- expand.grid(x1=seq(0,1,length=5), x2=seq(0,1,length=4))
y                   <- apply(X, 1, branin)
upsm                <- UPSM$new(sm= krigingsm$new(), UP=UPClass$new(X,y,Scale =TRUE))
CV             <- Resampling_Error$new()
PRESS_CV       <- CV$get_val(upsm)
print(" CV Resampling Error")
#> [1] " CV Resampling Error"
print(PRESS_CV)
#> [1] 18.67703
