Calibration-Based Cuffless Blood Pressure Estimation Using a Dilated-Residual Attention U-Net
Thomas Stogiannopoulos, Nikolaos Mitianoudis (Democritus University of Thrace)
Summary
Dual-stream 1D encoder-decoder on raw PPG + ECG: dilated residual convs, FiLM cross-signal modulation at the bottleneck, learned scale-wise fusion, attention-gated skips, mean-attention pooling head. PulseDB calibration-based subset (SBP 57–180, DBP 25–100 mmHg). MAE SBP 3.81 (ME −0.28 ± 5.54), DBP 2.03 (ME 0.38 ± 3.13), R² 0.92/0.93; BHS and IEEE-1708 grade A.
