Abstract: We proved that the phaseless sampling (PLS) in the linear-phase modulated shift-invariant space (SIS) V (eiα·φ), α = 0, is impossible even though the real-valued function φ enjoys the full ...
Many healthcare providers feel that UPIC audits often fall short, with flawed sampling and extrapolation techniques that dramatically exaggerate overpayment findings, exposing providers to undue ...
Abstract: Finite time-vertex graph signals (FTVGS) provide an efficient representation for capturing spatio-temporal correlations across multiple data sources on irregular structures. Although ...
