Manifold distance
WebDec 11, 2016 · The beautiful thing is that a differentiable manifold gives you tools to do that. This way, you can create a measure of distance (called a Riemannian metric), which allows you to calculate shortest paths between points even without ambient spaces. But it doesn't stop there. What are parallel lines? What happens to a local coordinate system? WebMy question is about computing the distance between two points in a Riemannian manifold. Suppose that ( M, g) is compact so that it is geodesically complete and …

(c) Manifold to manifold distance … WebIn order to address those limitations, we propose a novel density peak clustering algorithm using global and local consistency adjustable manifold distance in this paper. In the proposed algorithm, a novel manifold distance with exponential term and scaling factor is introduced to estimate local densities of all data points.
