摘要:

我们提出了一种新的方法来建模和学习向量场的物理系统,使用神经网络,明确满足已知的线性算子约束。为了实现这一点,目标函数被建模为潜在的势场的线性变换,该势场又由神经网络建模。选择该变换,使得目标函数的任何预测都保证满足约束。模拟和真实数据的例子证明了这种方法。

英文摘要:

We present a novel approach to modelling and learning vector fields from physical systems using neural networks that explicitly satisfy known linear operator constraints. To achieve this, the target function is modelled as a linear transformation of an underlying potential field, which is in turn modelled by a neural network. This transformation is chosen such that any prediction of the target function is guaranteed to satisfy the constraints. The approach is demonstrated on both simulated and real data examples.
