Abstract

fetched live from OpenAlex

The method of obtaining (bi)-orthogonal wavelets on intervals (boundary wavelets) by a direct approach is employed. The tensor product can then be applied for the construction of high-dimensional boundary wavelets. The ℓ<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</inf> optimization model integrating with such high-dimensional boundary wavelets for regularization was then used for image denoising and can be solved through the ADMM algorithm. Comparisons with the traditional wavelets (without boundary) are done to demonstrate the effectiveness of boundary wavelets and the advantages of the model with ADMM in the presence of large noise levels.

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.
