Abstract
The human hand possesses distinctive features which can reveal gender\ninformation. In addition, the hand is considered one of the primary biometric\ntraits used to identify a person. In this work, we propose a large dataset of\nhuman hand images (dorsal and palmar sides) with detailed ground-truth\ninformation for gender recognition and biometric identification. Using this\ndataset, a convolutional neural network (CNN) can be trained effectively for\nthe gender recognition task. Based on this, we design a two-stream CNN to\ntackle the gender recognition problem. This trained model is then used as a\nfeature extractor to feed a set of support vector machine classifiers for the\nbiometric identification task. We show that the dorsal side of hand images,\ncaptured by a regular digital camera, convey effective distinctive features\nsimilar to, if not better, those available in the palmar hand images. To\nfacilitate access to the proposed dataset and replication of our experiments,\nthe dataset, trained CNN models, and Matlab source code are available at\n(https://goo.gl/rQJndd).\n

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
