Accelerated Subspace-constrained Mean Shift
Subspace-constrained Mean Shift (SCMS) is an iterative algorithm for non-parametric ridge estimation. Although SCMS is computationally feasible, it is …
Manifold Scaffold Sampling
When data points exhibit salient geometric structure, density estimation and generative modeling can be more efficient by exploiting the data …
Kernel Density Estimation and Sampling on Riemmanian Submanifolds
For probability density estimation on Riemannian manifolds, many methods have been proposed, parametric or non-parametric. However, whether they can …
Newton Retraction as Approximate Geodesics on Submanifolds
Newton retraction is always stabler and faster than orthographic retraction, aka oblique projection.
