Summary

Shared patch embedding feeds a local dilated-conv encoder and a global AutoCorrelation encoder, fused by cross-attention, with a constrained dual-head SBP/DBP loss. Bayesian hyperparameter search and ablations on PulseDB. SBP/DBP MAE 7.46 / 4.72 mmHg, near-zero mean error; AAMI-compliant and BHS grade B for DBP only.
