Kind Code: A1 Abstract: A physically driven deep learning backward calculation method avoids problems existing in the backward calculation method, reduces calculation memory consumption in region division, and improves backward calculation accuracy. SOLUTION: A step 1) of initializing a range of an ...
In recent years, deep learning has been proven to be highly effective in addressing phase recovery problems. The two most direct deep learning phase recovery strategies are data-driven (DD) with supervised learning mode and physics-driven (PD) with self-supervised learning mode. DD and PD ...
因此融合physics-driven和data-driven的模型仍涉及折中。 本文所述的物理先验嵌入(Physics Prior Embedding)指的是强令模型本身满足被研究系统所具有的某些物理先验。这不同于一个相似的流行的名词:Physics Informed (as in PINN),这是将被研究系统所满足的方程作为“仿真器”从而为任意的采样点提供loss信号。 本文也...
We introduce physics informed neural networks -- neural networks that are trained to solve supervised learning tasks while respecting any given law of physics described by general nonlinear partial differential equations. In this two part treatise, we present our developments in the context of solving...
