Abstract

fetched live from OpenAlex

Cardiovascular disease (CVD) remains a leading cause of death and disability worldwide, underscoring the critical need for early detection and continuous monitoring.Wearable technologies have emerged as a promising solution, offering non-invasive, real-time assessment of physiological signals in daily life.Among these, seismocardiography (SCG)-a technique that NIBP, ICG, and PPG, respectively.This result demonstrates the feasibility of using a single motion sensor to estimate rich, multimodal cardiac information, offering a simplified and scalable alternative to traditional multi-sensor systems.Finally, we explore the use of synthetic SCG data to improve cross-domain pulmonary hypertension (PH) detection.We leverage generative models and introduce a dataset selection method to optimize the composition of synthetic and real training data.Our approach improves the out-of-distribution PH detection performance, increasing the area under the ROC curve from 0.51 to 0.86.These results highlight the potential of generative SCG modelling in a clinically relevant scenario with limited training data.Collectively, these contributions advance SCG as a viable and scalable modality for wearable cardiac monitoring.By improving signal robustness, addressing data scarcity, enabling multimodal estimation, and demonstrating clinical relevance, this work expands the role of SCG in both research and real-world applications.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
