Approximation of Functions over Manifolds: A Moving Least-Squares Approach

no code implementations2 Nov 2017 Barak Sober, Yariv Aizenbud, David Levin

The resulting approximant is shown to be a function defined over a neighborhood of a manifold, approximating the originally sampled manifold.

Manifold Approximation by Moving Least-Squares Projection (MMLS)

no code implementations22 Jun 2016 Barak Sober, David Levin

We assume that the data points are located "near" the lower dimensional manifold and suggest a non-linear moving least-squares projection on an approximating $d$-dimensional manifold.
