Abstract

fetched live from OpenAlex

The extraction of characteristics is one of the principal components of all form recognition systems. This work relates to the use of wavelet moments as characteristics for the recognition of manuscript characters. We propose here new families and new methods of treatment of this type of characteristic. Encouraging experimental results were obtained: the most discriminating 39 characteristics among 168 others were extracted and selected. These were validated using two classifiers, 1-NN and SVM. The first gives an error rate of 4.56% (leave-one-out), and the second an error rate of 2.99% (hold-out).

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.

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.
