Abstract
Double-base number systems (DBNSs) have recently gained recognition for the hardware implementation of low-power digital signal processing systems. This paper presents a genetic algorithm for the design of frequency response masking (FRM) digital filters over a single-digit DBNS system. This is based on designing a corresponding seed infinite precision coefficient digital filter (through continuous optimization), and on quantizing the resulting multiplier coefficients into single-digit DBNS coefficients via a look-up table. The resulting digital filter is encoded into a chromosome which is perturbed to form an initial population for the genetic algorithm. The salient feature of the resulting genetic algorithm is that it automatically leads to legitimate DBNS offspring digital filters after the operations of crossover and mutation, i.e. without any recourse to gene repair. Application to the design of a bandpass FRM digital filter produces a DBNS-coefficients digital filter with superior performance to that obtained by continuous optimization.

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
