Novel localized wave of modified Kadomtsev–Petviashvili equation

Abstract

In this paper, we investigate the data-driven localized solutions of Kadomtsev–Petviashvili (KP) and modified KP equation. Through the two-dimensional Miura transformation, the solutions of modified KP equation can be converted into the solutions of KP equation, but the process is not invertible in mathematics. Based on the neural network, the localized waves of modified KP equation are obtainned under an unsupervised trainning with the aid of two-dimensional Miura transformation and the initial and boundary conditions of solution of the KP equation. As the result of the different hyperparameters, three types of localized waves are found after the trainning, including the shape of kink, dark and kink-bell. The evolution and error dynamics of the predicted solutions are anzlyzed through the graphics.
