Web2 de ago. de 2024 · While there is currently a lot of enthusiasm about "big data", useful data is usually "small" and expensive to acquire. In this paper, we present a new paradigm of learning partial differential equations from small data. In particular, we introduce hidden physics models, which are essentially data-efficient learning machines capable of … Web1 de ago. de 2024 · In Section 3, we first briefly review the basics of GPR and then present the hidden physics model for the elastic wave equations to estimate the P-wave and S … Web10 de mar. de 2024 · In this article, we introduce a modular hybrid analysis and modeling (HAM) approach to account for hidden physics in reduced order modeling (ROM) of parameterized systems relevant to fluid dynamics.
