Artificial Intelligence for Studying Interactions of Solitons and Peakons
This paper develops an Artificial Intelligence (AI) algorithm, specifically Physics-Informed Cellular Neural Networks (PICNNs), to study the interactions of solitons and peakons arising from the Boussinesq Paradigm and b-equations in fluid dynamics. Leveraging the power of machine learning and automatic differentiation, PICNNs offer precise, real-time solutions for complex nonlinear partial differential equations (PDEs). The algorithm integrates physical laws into the learning process, enabling fast programming and highly accurate approximations across various scientific domains, including fluid dynamics, material science, and quantum mechanics. The core advantage lies in CNNs' ability to accurately model nonlinear PDEs and deliver solutions in real time.
