Analysis of Eigenvalue Decomposition-Based Late Reverberation Power Spectral Density Estimation

Many speech dereverberation techniques require an estimate of the late reverberation power spectral density (PSD). State-of-the-art multi-channel methods for estimating the late reverberation PSD typically rely on 1) an estimate of the relative transfer functions (RTFs) of the target signal, 2) a model for the spatial coherence matrix of the late reverberation, and 3) an estimate of the reverbe...

Density functional energy decomposition into one- and two-atom contributions.

The present work provides a generalization of Mayer's energy decomposition for the density-functional theory (DFT) case. It is shown that one- and two-atom Hartree-Fock energy components in Mayer's approach can be represented as an action of a one-atom potential V(A) on a one-atom density rho(A) or rho(B). To treat the exchange-correlation term in the DFT energy expression in a similar way, the...

Eigenvalue inclusions via domain decomposition

We describe a method for the calculation of guaranteed bounds for the K lowest eigenvalues of second-order problems with Neumann boundary conditions. Using P2 approximations for the eigenfunctions and RT1 approximations for the gradients of the eigenfunctions in H(div; ), an error bound for the eigenfunctions is established for weak approximations in H1( ). In addition, the rest of the spectrum...
