Abstract

fetched live from OpenAlex

Infrared molecular fingerprinting of human blood samples provides a powerful, minimally invasive approach for disease detection and health monitoring. However, ethical and legal constraints often limit the sharing of real patient data collected from clinical studies. In this work, we present a synthetic dataset of blood-based infrared molecular fingerprints, generated using multivariate Gaussian models fitted on real measurements from a large case-control study targeting various cancer types. The synthetic dataset retains the statistical and physical properties of real molecular fingerprints, enabling the development and validation of analytical methodologies without compromising patient privacy. We demonstrate that the provided artificial dataset can serve as a proxy for real data in methodological research, facilitating reproducibility and collaboration in biomedical spectroscopy. This approach offers a practical solution for overcoming ethical barriers in clinical data sharing in spectroscopic biomarker research.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
