Abstract

fetched live from OpenAlex

Linear phase IIR filters can be designed from FIR prototypes by using standard model reduction techniques. These techniques are based upon obtaining a balanced realization of the original system, and then removing the weakly controllable and observable states. Some standard model reduction techniques are explored as well as an extension to discrete time of a previously proposed continuous time frequency weighting technique. The techniques are applied to the design of two example filters. In both cases, the new frequency weighting technique produces a lower order filter, at the cost of increased ripple in the pass-band group delay.< <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.
