Reformulating Neural Operators in $d+1$ Dimensions for Embedding Evolution

Researchers introduce a reformulated Neural Operators framework that models embedding evolution in d+1 dimensions, using Fourier-based operators to improve function space mappings. The approach demonstrates superior performance across multiple benchmarks while reducing computational overhead compared to traditional embedding-scaling methods.

When Attention Beats Fourier: Multi-Scale Transformers for PDE Solving on Irregular Domains

Researchers introduce Multi-Scale Attention Transformer (MSAT), a deep learning architecture that outperforms Fourier-based neural operators for solving PDEs on irregular domains. The model achieves 3.7x better accuracy than FNO on complex geometry problems while running 3,500x faster than competing approaches, with theoretical bounds explaining when attention mechanisms beat frequency-domain methods.
