Abstract

fetched live from OpenAlex

In this paper, two novel image search mechanisms are introduced and compared against the traditional linear approach and one another. These feature detection algorithms mimic two natural human search strategies which make them suitable for faster feature detection within pixelated images. Unlike linear approaches where pixel-by-pixel probing is required, these mechanisms provide faster feature detection due to their non-linear nature. The proposed algorithms are suitable for various feature detection applications, such as face detection, image labelling, abnormality detection in medical images, and the like. Raindrop and Bouncing mechanisms outperformed the linear approach by 75.2% and 89.8% respectively when tested separately against the linear algorithm. Moreover, after conducting extensive experiments with various conditions on all three algorithms, Raindrop detected 50.85% of the features while Bouncing and linear algorithms were successful in 35.08% and 14.07% of the tests respectively.

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.
