FIG. 7. — No feature selection: $u_{t} = f^{u} (u, u_{x}, u_{x x}, v, v_{x}, v_{x x})$ and $v_{t} = f^{v} (u, u_{x}, u_{x x}, v, v_{x}, v_{x x})$ . (a)–(d) Simulation results of the two methods for $u$ and $v$ . (e)–(h) The normalized absolute differences from the “ground truth” LB simulations for $u$ and $v$ .
