Weformer: Adaptive spectral cross-variable transformer for long-horizon weather forecasting

This work proposes Weformer, a Transformer-based architecture purpose-built for sensor-derived weather time series, and introduces two core innovations: a Frequency-driven Cross-Variable Rotary Position Embedding (CrossVarRoPE) that extracts dominant spectral patterns via the Fourier transform and injects adaptive, cro...
