Abstract
This paper presents a fast algorithm to compute the 8times8 discrete cosine transform (DCT), using a new error-free encoding which partially overcomes the quantization error of digital implementation due to finite-precision effect. The proposed encoding scheme, named as algebraic integer quantization (AIQ), is achieved by obtaining the exact representation of the transcendental functions. The proposed AIQ-based 8times8 DCT can be used as an alternative transform for H.264 encoders, which results in a simple, parallel, and multiplication-free architecture, and also minimizes the complexity and the hardware cost of the quantizer/dequantizer. The authors propose an initial FPGA implementation where the system can run at 100 MHz, and satisfies all real time constraints for digital multimedia applications

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
