  1. Hybrid Iterative Neural Low-Regularity Integrator for Nonlinear Dispersive Equations

    cs.LG 2026-05 unverdicted novelty 7.0

    A hybrid solver-neural framework achieves global error O(τ^γ ln(1/τ)) for nonlinear dispersive equations by training a lightweight network on the residual defect inside the solver loop while preserving uniform stability.

  2. Hybrid Iterative Neural Low-Regularity Integrator for Nonlinear Dispersive Equations

    cs.LG 2026-05 unverdicted novelty 7.0

    HIN-LRI augments a low-regularity integrator with a latent-manifold neural correction trained end-to-end on trajectory error to improve accuracy on nonlinear dispersive equations with rough data.

  3. Hybrid Iterative Neural Low-Regularity Integrator for Nonlinear Dispersive Equations

    cs.LG 2026-05 unverdicted novelty 5.0

    HIN-LRI augments low-regularity integrators with a neural correction term trained end-to-end via solver-in-the-loop to achieve a global error bound of order τ^γ ln(1/τ) and improved accuracy on dispersive PDE benchmarks.
