WebAug 28, 2024 · With the advent of deep matrix learning [24,25,26], literature proposes a deep SPD matrix learning model, which exploits RBF kernel function to aggregate convolution features into SPD matrices. Their ultimate goal is to convert the SPD matrix from a Riemannian manifold to another more distinctive manifold. WebThe paper proposes a spectral mixture of laplacian kernel with a levy process prior on the spectral components. This extends on the SM kernel by Wilson, which is a mixture of gaussians with no prior on spectral components. A RJ-MCMC is proposed that can model the number of components and represent the spectral posterior.
