The Potential of Artificial Intelligence and Deep Learning
The remarkable potentials of Artificial Intelligence (AI) and Deep Learning have paved the way for a variety of fields ranging from computer vision and language modeling to healthcare, biology, and whatnot. A new area called Scientific Machine Learning (SciML), which combines classic modeling methods based on partial differential equations (PDEs) with machine learning’s approximation capabilities, has recently been in the talks.
Scientific Machine Learning (SciML)
SciML consists of three primary subfields, which include PDE solvers, PDE discovery, and operator learning. While PDE discovery seeks to determine a PDE’s coefficients from data, PDE solvers use neural networks to approximate a known PDE’s solution. The third subfield, i.e., Operator learning, is a specialized method that aims to find or approximate an unknown operator, which is typically the differential equation solution operator.
Practical Applications and Value
Operator learning is especially helpful in situations when it’s necessary to determine the properties of a dynamic system or PDE. It addresses complex or nonlinear interactions where traditional methods may be computationally demanding. The study has demonstrated that operator learning also requires numerical PDE solvers to speed up the learning process and approximate PDE solutions. For accurate and quick results, these solvers must be integrated efficiently. The caliber and volume of training data greatly impact the effectiveness of operator learning.
