TF-SNO: Time-Frequency Gated Spectral Neural Operators for Learning Non-Stationary Partial Differential Equations

Researchers propose Time-Frequency Gated Spectral Neural Operators (TF-SNO), a machine learning framework that dynamically adapts its spectral response to model non-stationary partial differential equations where frequency content changes over time. The approach outperforms existing spectral neural operators on six benchmarks by using state-dependent modulation rather than static spectral filters.

Curvature-aware dynamic precision approach for physics-informed neural networks

Researchers propose a curvature-aware dynamic precision controller for physics-informed neural networks (PINNs) that automatically switches between single-precision (FP32) and double-precision (FP64) during training. The method matches full FP64 accuracy while reducing computational costs, addressing a critical trade-off in simulating complex physical systems.
