WebSep 23, 2024 · Revealing such a manifold is a nonlinear dimensionality reduction approach where the extra dimensions mostly represent noise and minor image features. As GGD is focused on an eigenvalues analysis based on an underlying manifold of the patch space, this denoising scheme is considered to be a patch-based non-local dictionary learning … WebJul 2, 2014 · This work introduces the empirical cross-gramian for multiple-input-multiple-output systems. The cross-gramian is a tool for reducing the state space of control systems, by conjoining controllability and observability information into a single matrix and does not require balancing. Its empirical gramian variant extends the applicability of the cross …
