Abstract

fetched live from OpenAlex

Smart face identification is widely used in smart city and smart healthcare. However, smart face identification technology is susceptible to envirnmental factor, such as illumination, mask, and expression. In order to fully extract facial feature information, we fuse an improved local binary pattern (LBP) and the histogram of oriented gradients (HOG) to extract the texture and detailed features on the face. The 2DPCA + PCA is used to reduce the dimensionality of the extracted features. The 2DPCA sloves the issue that the model is too complex when the feature dimension is very high. The feature reduction reduces the calculation scale and increases the calculation speed. Finally, experimental results on ORL and Yale face databases show that the feature extraction based on the fusion of improved LBP and HOG complement with each other. Compared with other recognition algorithms, the improved algorithm has higher recognition and identification rate.

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.
