generateSparsePoints: generateSparsePoints

In VBmix: Variational Bayesian Mixture Models

Description

generates a set of points pairwise-separated by a minimal distance. Is not guaranteed to converge: when maxit is reached, current points are returned.

Usage

generateSparsePoints(npoints, dim = 2, span = 10, mindist = 2, maxit = 20)

Arguments

npoints	number of points to generate (i.e. in a matrix with elements as rows.
dim	number of variables to generate.
span	[-span, span] is used as bounds to uniform sampling for all variables.
mindist	minimal distance that each element should have with all others. the "control" C routine is used to perform this verification. All points that do not respect this constraint are resampled.
maxit	maximal number of iterations before current elements are returned.

Value

matrix with well separated elements as its rows.
