lle_scurve

Example application on a three-dimensional S-curve dataset.

Performs the LLE alogrithm on a three dimensional S-curve, which is a standard example for data embedding algorithms.

lle_scurve(N = 800, k = 12, ss = FALSE, p = 0.5, reg = 2, 
                    iLLE = FALSE, v = 0.8)

`N`	number of samples. See `lle`.
`k`	number of neighbours. See `lle`.
`ss`	a logical values indicating wheather to perform subset selection. See `lle`.
`p`	amount of data remaining after subset selection. See `lle`.
`reg`	regularisation method. See `lle`.
`iLLE`	a logical values indicating wheater to use iLLE. See `lle`.
`v`	threshold parameter for intrinsic dimension. See `lle`.
