Abstract

fetched live from OpenAlex

This paper presents a novel approach for face based biometric recognition. The proposed method is based on the sorted index numbers (SIN) of appearance based facial features. A new algorithm is introduced to measure the similarity between SIN vectors. Due to the non-invertibility of the transformation from the original features to the SIN vectors, the proposed method can preserve the privacy of the users. The effectiveness of the proposed method is tested on a large generic data set, which contains images from several well known face databases. Experimental results demonstrate that the proposed solution may improve the recognition accuracy in both identification and verification scenarios.

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.
