Physics-guided machine learning
Webb1 feb. 2024 · Physics-informed machine learning (PIML) is an emerging paradigm that aims to leverage the wealth of physical knowledge for improving the effectiveness of machine learning models [33]. By the PIML methods, physical principles are often used as the ‘prior’ knowledge to enhance the power of the machine learning models. WebbD. Theory-guided learning of dynamical systems It is crucial to have a machine learning model which is consistent with the physics of the dynamical system. [11] has shown how physics can be used to do better data-driven discoveries. Theory-guided design, learning, refinement of the machine learning model has been presented. In [12], [13] a
