Abstract
We propose an affine extension to ADDs (AADD) capable of compactly representing context-specific, additive, and multiplicative structure. We show that the AADD has worstcase time and space performance within a multiplicative constant of that of ADDs, but that it can be linear in the number of variables in cases where ADDs are exponential in the number of variables. We provide an empirical comparison of tabular, ADD, and AADD representations used in standard Bayes net and MDP inference algorithms and conclude that the AADD performs at least as well as the other two representations, and often yields an exponential performance improvement over both when additive or multiplicative structure can be exploited. These results suggest that the AADD is likely to yield exponential time and space improvements for a variety of probabilistic inference algorithms that currently use tables or ADDs. 1

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
