In this paper we present a Fourier feature based deep domain decomposition method (F-D3M) for partial differential equations (PDEs). Currently, neural network methods are actively developed solving PDEs, but their efficiency can degenerate problems with high frequency modes. new F-D3M strategy, overlapping is conducted the spatial domain, such that modes be reduced to relatively low ones. each ...

Spatial aliasing is an unwanted side effect that produces artifacts during seismic data processing, imaging and interpolation. It is often caused by insufficient spatial sampling of seismic data and often happens in CMP (Common Mid-Point) gather. To tackle this artifact, several techniques have been developed in time-space domain as well as frequency domain such as frequency-wavenumber, frequen...
