f_ncut {PPCI} | R Documentation |
Normalised Cut Across a Hyperplane
Description
Finds the normalised cut across the best hyperplane orthogonal to a given projection vector. Used as projection index for projection pursuit to find minimum normalised cut hyperplanes.
Usage
f_ncut(v, X, P)
Arguments
v |
a numeric vector of length ncol(X) |
X |
a numeric matrix (num_data x num_dimensions) to be projected on v |
P |
a list of parameters including (at least) $s (positive numeric scaling parameter), $nmin (positive integer minimum cluster size) |
Value
the value of the normalised cut across the best hyperplane orthogonal to v
