Improve the Fitting Accuracy of Deep Learning for the Nonlinear Schr\"odinger Equation Using Linear Feature Decoupling Method

These results demonstrates that the FDD model propagation of optical pulses through optical fiber channel, achieves superior accuracy over the non-decoupling model which is the cornerstone for studying nonlinear optics and and adapts effectively across a broader range of boundary optical fiber communication[1][2]. The NLSE is non-analytical conditions.
