M_rozza: Manifolds from Rozza et al. (2012)

In intrinsicDimension: Intrinsic Dimension Estimation

Description

Generates data sets from Rozza et al. (2012). M14 is an 18-dimensional manifold with intrinsic dimension 72. M14 is a 24-dimensional manifold with extrinsic dimension 96. Note that M14 and M15 are not uniformly sampled.

Usage

m14Manifold(Ns)
m15Manifold(Ns)

Arguments

Ns	number of data points.

Value

A 72-dimensional or 96-dimensional data set respectively.
