WebThe mean of the SPD matrices plays an important role in classification. Since the neighborhood of Riemannian manifold is local homeomorphic to its tangent space, the trinational classifier can be performed on tangent space to obtain high classification performance . However, large neighborhood will lead to large distortion between … Weblinear optimization problem and the manifolds concerned generally do not have an analytic expression. Therefore, small transformations of the pattern xare approximated by a tangent subspace to the manifold at the point x. This subspace is obtained by adding to x a linear combination of the vectors
