Figure 7. The mKdV equation. Top: a breather solution to the mKdV equation (left panel) is compared to the predicted solution to the learned equation. The model correctly exhibits the dynamics behavior and accurately reproduces the solution with a relative ${{\mathbb{L}}}_{2}$ error of 1.05 × 10−2 . Bottom: the comparison of the predicted solutions and exact solutions is presented.
