WebFeb 29, 2024 · Manifold learning methods shed light on the geometric nature of the dataset at hand, before task-specific modeling requirements kick in. If one has an understanding of the “shape” of the data, one can potentially develop specific algorithms that effectively use that structure. Manifold learning as a dimensionality reduction tool can be seen ... Web3. Curvature-aware regularization In general, the curvature of a Riemannian manifold M is captured by a fourth-order tensor called the Riemann curvature tensor. Then, how the manifold M (of dimen-sion m) is curved with respect to the ambient manifold M (of dimension n), is characterized by the difference of the corresponding curvature tensors ...

Curvature-Aware Regularization on Riemannian Submanifolds

Webwhere ">0 is the learning rate, 2[0;1] is the mo-mentum coe cient, and rf( t) is the gradient at t. Since directions d of low-curvature have, by de ni-tion, slower local change in their … WebTo be more specific, the traditional manifold learning does not consider the curvature information of the embedded manifold. In order to improve the existing algorithms, we propose a curvature-aware manifold learning algorithm called CAML. Without considering the local and global assumptions, we will add the curvature information to the process ... permittivity explained
