MeshTok: Efficient Multi-Scale Tokenization for Scalable PDE Transformers
Researchers have introduced MeshTok, a novel tokenization framework designed to improve the efficiency and accuracy of Transformers used for solving partial differential equations (PDEs). Unlike conventional methods that divide computational domains uniformly, MeshTok employs an adaptive approach inspired by adaptive mesh refinement. This technique selectively refines regions with complex features, creating a heterogeneous set of tokens that capture both global context and local details within a single Transformer sequence. Experiments show MeshTok offers a better efficiency-accuracy trade-off compared to uniform-grid baselines, suggesting its potential as a scalable principle for neural PDE modeling. AI
