Abstract

fetched live from OpenAlex

We introduce a structured approach that leverages AI to accelerate scientific discoveries. We showcase the efficacy of this technique via a proof-of-concept study identifying markers of sex in retinal images. Our methodology consists of four stages: In Phase 1, CNN development, we train a VGG model to recognize patient sex from retinal images. Phase 2, Inspiration, involves reviewing post-hoc interpretation tools' visualizations to draw observations and formulate exploratory hypotheses regarding the CNN model's decision process. This yielded 14 testable hypotheses related to potential variances in vasculature and optic disc. In Phase 3, Exploration, we test these hypotheses on an independent dataset, of which nine demonstrated significant differences. In Phase 4, Verification, five out of nine these nine hypotheses are re-tested on a new dataset, verifying five of them: significantly greater length, more nodes and branches of retinal vasculature, a larger area covered by vessels in the superior temporal quadrant, and a darker peri-papillary region in male eyes. Finally, we conducted a psychophysical study and trained a group of ophthalmologists (N=26) to identify these new retinal features for sex classification. Their performance, initially on par with chance and a non-expert group (N=31), significantly improved post-training (p<.001, d=2.63). These outcomes illustrate the potential of our methodology in leveraging AI applications for retinal biomarker discovery.

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.
