random
fun randomProjection(n: Int, p: Int, sparse: Boolean = false, vararg columns: String): RandomProjection(source)
Random projection for dimensionality reduction.
Return
the RandomProjection model.
Parameters
n
the dimension of input space.
p
the dimension of feature space.
sparse
true to generate sparse random projection, false for Gaussian random projection.
columns
optional column names for projected data frame.
