Does Scale Stealthily Hijack Attention? PMDformer’s Simple Subtraction Fix for Long-Term Forecasting

The paper identifies scale differences between patches as a hidden source of attention distortion in long‑term time‑series forecasting, introduces PMDformer with Patch Mean Decoupling, Neighbor Variable Attention, and Trend Recovery Attention, and demonstrates state‑of‑the‑art accuracy and efficiency across eight benchmark datasets.
