Striking The Right Balance: Three-Dimensional Ocean Sound Speed Field Reconstruction Using Tensor Neural Networks

1 code implementation9 Aug 2023 Siyuan Li, Lei Cheng, Ting Zhang, Hangfang Zhao, Jianlong Li

Accurately reconstructing a three-dimensional ocean sound speed field (3D SSF) is essential for various ocean acoustic applications, but the sparsity and uncertainty of sound speed samples across a vast ocean region make it a challenging task.

Tensor-based Basis Function Learning for Three-dimensional Sound Speed Fields

no code implementations21 Jan 2022 Lei Cheng, Xingyu Ji, Hangfang Zhao, Jianlong Li, Wen Xu

In particular, a tensor-based basis function learning framework is proposed, which can include the classical basis functions (using EOFs and/or Fourier basis functions) as its special cases.
