Abstract

fetched live from OpenAlex

A neural model approach to adaptively calculating the principal components of the covariance matrix of an input sequence is proposed. The algorithm is based on the successive application of the modified Hebbian learning rule proposed by E. Oja (1982) on every covariance matrix which results after calculating the previous eigenvectors. This is equivalent to removing one dimension of the orthogonal space in which the data could be represented. Adopting a modification rule for the learning rate achieves faster convergence than that obtained when using other models. The optimal learning rate is calculated by minimizing an error function of the learning rate along the gradient descent direction.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
