Abstract
In this paper, a novel method is proposed to design FIR filters with minimum orders. The original design problem is formally expressed as an l <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> -norm optimization problem. An iterative procedure is developed to solve this problem. Although, for a set of given specifications, the proposed method is not guaranteed to find the optimal solution, one can greedily decrease the filter order until the specifications cannot be further satisfied. Simulation results demonstrate that the greedy search needs a limited number of iterations, and the overall computational complexity is not too high. Compared to the classical estimation methods, the proposed method can be utilized for general design specifications. The performance of the proposed design method can be verified by a large number of simulations.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
