Abstract

fetched live from OpenAlex

The convergence rate and stability of the filter will be influenced and the filter will diverge because the filtering covariance matrix becomes symmetrical or negative elements appear in the filtering covariance matrix due to calculation error.Based on the algorithm of maneuvering acceleration current statistical model adaptive filtering,the adaptive kalman filtering algorithm based on QR matrix decomposition is presented in this paper.The filtering covariance matrix is decomposed into two matrixes in order to keep the matrix positive.The results of the adaptive kalman filtering algorithm based on QR matrix decomposition is evaluated through Montecarlo simulation.

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.
