Researchers have developed a novel Multi-Head Residual-Gated DeepONet (MH-RG) architecture designed to better model coherent nonlinear wave dynamics. This new framework integrates compact physical descriptors of the initial state as residual modulation factors, complementing the standard DeepONet state pathway. The MH-RG architecture incorporates a pre-branch residual modulator, a branch residual gate, and a trunk residual gate with a low-rank multi-head mechanism to capture multiple conditioned response patterns efficiently. Evaluations on benchmarks involving nonlinear conservative and dissipative dynamics demonstrate that MH-RG DeepONet achieves lower error rates while better preserving phase coherence and key dynamical quantities compared to existing feature-augmented baselines.
