Description

It is used by the function random.subspace to randomly select the indices of the variables used for the random subspace projections. It randomly select a subset of the indices, that is a set of positive integers that correspond to the selected variables

Usage

random.component.selection(d = 2, d.original = 10)

vector of the selected features: it contain the indices of the components randomly selected

Arguments

d

subspace dimension

d.original

dimension of the space from which components are randomly selected
