摘要：

In this report, we propose a deep learning-based “Polynomial Extractor for Rogue Wave Patterns (PE-RWP)”. This approach replaces traditional asymptotic analysis of high-order RW solutions under large parameter conditions, enabling automatic and precise identification of polynomial characteristics within RW patterns. The unique dual-branch network architecture (with a regression branch for identifying corresponding polynomial types) enables PE-RWP to effectively output this generalized polynomial hierarchy and recognize RW patterns subjected to arbitrary scaling and rotational transformations. Furthermore, as an application based on the mathematical theory of RW patterns, we leverage the Y-V polynomials output by PE-RWP to achieve unsupervised localization of Peregrine waves through deep learning methods. Finally, through extensive experimental evaluation, both problems polynomial extraction and Peregrine wave localization are effectively solved with high accuracy.
