Abstract

fetched live from OpenAlex

Since the gradient magnitude of the ear region is large, a method of extracting ROI based on gradient and determining human ear by SVM is proposed in this paper. The mean value of gradient magnitude in the regions, of which size is equal to ear, is computed by the extracting ROI method. The several regions of large gradient including ear region are extracted by fit threshold. In order to reduce searching range, the skin color model to detect human face region from the head image is used. Through the fast searching ear region algorithm, the ear region candidates can be extracted quickly. Finally, the vector dimension of the extracted region is reduced by principle component analysis method, and then the ear region is determined by SVM. Experimental results indicate that the method is effective.

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.
