Log-likelihood method to select initial values of multichannel non-negative matrix factorization

Abstract: A multichannel extension of non-negative matrix factorization (NMF) associates the spatial property of the sources with each of the NMF bases. An initial-value selection method based on ...

INITIAL BOUNDARY VALUE PROBLEM FOR SEMILINEAR HYPERBOLIC EQUATIONS AND PARABOLIC EQUATIONS WITH CRITICAL INITIAL DATA

We study the initial boundary value problem of semilinear hyperbolic equations utt – Δu = f(u) and semilinear parabolic equations ut – Δu = f(u) with critical initial data E(0) = d (or J(u₀) = d), ...

System Power Imbalance Estimation Utilizing Linear Component of Local Frequency

Abstract: This letter indicates that initial transient local frequency deviation is composed of linear component and combination of $(n-1)$ electro-mechanical (EM) modes via solving the initial value ...
