WebWe propose a deterministic-statistical method for an inverse source problem using multiple frequency limited aperture far field data. The direct sampling method is used to obtain a disc such that it contains the compact support of the source. The Dirichlet eigenfunctions of the disc are used to expand the source function. Then the inverse problem is recast as a … WebA smooth inverse frequency-based word vector averaging technique for sentence em-beddings was proposed by [4]. However, because the final represen-tation is in the same space as the word vectors, these methods are only capable of capturing the meaning of a single sentence. Thus,
