Abstract
This paper presents a novel error-free (infinite-precision) architecture for the fast implementation of 8x8\n2-D Discrete Cosine Transform. The architecture uses a new algebraic integer encoding of a 1-D radix-8 DCT\nthat allows the separable computation of a 2-D 8x8 DCT without any intermediate number representation\nconversions. This is a considerable improvement on previously introduced algebraic integer encoding techniques\nto compute both DCT and IDCT which eliminates the requirements to approximate the transformation matrix ele-\nments by obtaining their exact representations and hence mapping the transcendental functions without any\nerrors. Apart from the multiplication-free nature, this new mapping scheme fits to this algorithm, eliminating any\ncomputational or quantization errors and resulting short-word-length and high-speed-design.

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
