Abstract

fetched live from OpenAlex

The pathophysiology of glaucoma is still unclear, and the velocity of disease progression is hard to predict. OCT allows to quantify anatomical characteristics that can be correlated with glaucoma stage, but new dynamic biomarkers based on tissue biomechanics are actively sought. However, noise in OCT images hampers the detailed analysis of time series. Here, we present a method to stabilize and denoise OCT videos using the redundancy of the data to create single heart cycle videos, which allow a precise analysis of the movement of the tissues. This approach is computationally low-cost, simple to execute and easy to implement in a clinical setting.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
