High frequency scattering
Web27 de fev. de 2015 · 1 INTRODUCTION. High-frequency (f > 1 Hz) seismograms show completely different features compared to those of low-frequency (f < 1 Hz) seismograms due to seismic wave scattering of short-wavelength components during propagation in heterogeneous structure.Heterogeneities in the Earth, which especially cause seismic … Web6 de jun. de 2024 · A wavelet scattering transform builds translation invariant, stable, and informative signal representations. It is stable to deformations and preserves class discriminability, which makes it particularly effective for classification. We refer to [ 17 – 20] for its excellent practical performance for classification.
