find_coords: Calculate embedded data.

In lle: Locally linear embedding

Description

Calculates the embedded data of dimension m using the weight matrix.

Usage

find_coords(wgts, nns, N, n, m)

Arguments

wgts	weight matrix calculated by find_weights.
nns	matrix of neighbours calculated by find_nn_k or find_nn_eps.
N	number of samples.
n	dimension of the original data.
m	intrinsic dimension of the data.

Value

Y	matrix containing the embedded data.

Examples

	data( lle_scurve_data )
	X <- lle_scurve_data
	nns <- find_nn_k(X,5)
	wgts <- find_weights(nns,X,2)
	Y <- find_coords( wgts$wgts, nns, dim(X)[1], 3, 2 )
