Geometric Feature Learning for Functional Data Valued on the Symmetric Positive Definite Manifold

Researchers introduced MatFAE, a functional neural network that learns trajectories on the Riemannian manifold of symmetric positive definite (SPD) matrices, according to a new arXiv paper (arXiv:2609…
