Hidden physics models
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. The hybrid ROM framework is based on using first principles to model the known physics in conjunction with utilizing the data … Web1 de ago. de 2024 · Therefore, the hidden physics model can be regarded as a kind of PDE-constrained GPR in which model parameters are trained as hyperparameters of the GPR scheme. By only requiring a limited number of sparse and noisy measurements, the hidden physics model can accurately infer the model parameters and the solutions of …

WebAbstract. 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 leveraging the … WebWe introduce Hidden Physics Models, which are essentially data-efficient learning machines capable of leveraging the underlying laws of physics, expressed by time …
