UnverifiedRepresenting Fourier spectral components as structures in a two-dimensional frequency-amplitude space can improve impact-echo defect classification, and this improvement goes beyond the effect of merely smoothing along the frequency axis.76% similarUnverifiedRALD multiplies both the drift term and the noise covariance of the reflected Langevin dynamics by the same state-dependent scaling factor.65% similar
