Abstract

fetched live from OpenAlex

We present a new fast spatially recursive least-squares (SRLS) algorithm with exponentially fading memory for adaptive estimation of two-dimensional (2-D) nonstationary simultaneous autoregressive (SAR) model parameters. The computational complexity of the new algorithm is 8m/sup 3/2/+6m multiplications and divisions per recursion (MADPR) in contrast with 15m/sup 3/2/+16m MADPR of the best existing algorithm, where m is the number of the estimated model parameters. The new algorithm has the same statistical properties and tracking capability, compared with the existing algorithms. The derivation of the algorithm and the computer simulation results are given in the paper.< <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.
