    Prediction of self-similar waves in tapered graded index diffraction decreasing waveguide by the A-gPINN method

    In this paper, an adaptive gradient-enhanced physics-informed neural network method(A-gPINN) is proposed to investigate the dynamics of solitons in tapered refractive index waveguides. A-gPINN method adopts ad...
