Hidden physics models
WebDeep Hidden Physics Models. A long-standing problem at the interface of artificial intelligence and applied mathematics is to devise an algorithm capable of achieving human level or even superhuman proficiency in transforming observed data into predictive mathematical models of the physical world. 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-wave velocities, density. In Section 4, several numerical examples are provided to demonstrate the effectiveness of the method. Finally, we conclude in Section 5.
