spanfill {OSFD} | R Documentation |
Generate points to approximate the space spanned by the existing points
Description
spanfill
generates points to approximate a space based on existing points.
These approximate points can be used to find local fill distance in the space or be used as candidate points in active learning.
Usage
spanfill(X, bound = FALSE)
Arguments
X |
a matrix specifying the existing points |
bound |
a binary variable indicating whether to bound the generated points to 0 to 1 in each dimension. If bound=TRUE, all the generated points will be projected to the unit hypercube. The default value is FALSE. |
Details
spanfill
generates points to approximate the space spanned by the existing points. Details can be found in Wang et al. (2024).
Value
a matrix of the generated points to approximate the space.

Examples
X = matrix(runif(20), ncol=2)
