TinyCardioUNet is a lightweight UNet architecture that translates chest‑worn inertial measurement unit (IMU) data into electrocardiography (ECG) signals. It processes all six IMU axes, refines its bottleneck with a graph neural network to capture inter‑axis dependencies, and reduces parameters via tensor decomposition with automatic variational Bayesian rank selection. On a public dataset, the model achieves an RMSE of 0.098 and a Pearson correlation of 0.677 using only 36.0k parameters, while maintaining robustness to additive noise.

The paper introduces a deep learning-based signal quality assessment model that differentiates clean from noisy ambulatory ECG recordings. It is trained on the Copenhagen Center for Health Technology-Contextualized Arrhythmia Database, the first ambulatory ECG database that includes both physical and patient-reported contextual data. The model maintains stable performance across other datasets such as MIT and PhysioNet/CinC Challenge 2021, and the study demonstrates how the model can be used to investigate complex ECG noise in conjunction with contextual information.

The paper introduces DCGCNet, a dual-codebook graph collaborative network that jointly reconstructs ECG signals and classifies atrial fibrillation. It incorporates a local‑global contrastive module for noise‑invariant feature learning and an adaptive codebook vector quantizer to prevent codebook collapse. The model achieves state‑of‑the‑art intra‑dataset performance and consistently attains AUC > 0.98 across seven cross‑dataset settings, even under realistic noisy conditions.
