AOT-POT adaptively reshapes complex PDE solution operators via input-dependent transformations and parallel stream mixing to enable effective large-scale pre-training, yielding SOTA results on 12 benchmarks with minimal added parameters.
ST-PT turns transformers into explicit factor graphs for time series, enabling structural injection of symbolic priors, per-sample conditional generation, and principled latent autoregressive forecasting via MFVI iterations.
MH-PINN compactifies unbounded domains with mapping and enforces wave boundary conditions through network architecture for efficient, accurate simulations.
A physics-informed MLP reconstructs high-fidelity 4D spectra from only 1/32 of the samples in experimental 2DIR hyperspectral imaging.
Graph-based summary statistics on pulsar timing residuals detect SGWB down to strain amplitude 1.2e-15 and yield 2.3 sigma evidence in NANOGrav 15-year data via clustering coefficient and edge weight measures.
Introduces Laplace-approximated Bayesian PINNs for automatic loss-weight optimization when solving PDEs such as heat, wave, and Burgers equations.
