Abstract

fetched live from OpenAlex

Historical Preamble When I arrived in Cambridge in the late 1970s to work with the late Fergus Campbell, the notion of critical periods for visual development was already well established through the seminal works of Hubel and Wiesel (1967), Blakemore (1976), and others (see Daw, 1995). The clinical implication of this was also recognized, namely, that visual improvements from the patching treatment of amblyopia were likely to be strongly age dependent and ineffective after the age of 7 to 8 years. At that time, the wisdom of Sir Stewart Duke-Elder held sway: “for patching to work it needs to be total and complete, day and night.” Fergus always felt that the stronger the statement, the more likely it was to be wrong. In fact, at that time, I remember his method for choosing research projects for graduate students. He would go to his bookshelf and choose at random one of Duke-Elder's System of Ophthalmology volumes, open it at random and locate a definitive statement on some visual topic. “Let's show this is wrong,” he would say, and the die was cast for what usually turned out to be another fruitful piece of research. Fergus felt that some form of active stimulation would be better than the passive viewing that resulted from patching. He was enamored with the idea of the visual cortex as a spatial frequency analyzer, and because my early results suggested amblyopes suffered from severe spatial distortions (Hess et al., 1978), his first suggestion for a new therapy was to show a single spatial frequency at sequential orientations to help their visual cortex “sort out” what we hypothesized were anomalous interactions between these spatial analysers.

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.
