Abstract
This study introduces a training pipeline comprising two components: the Encoder-Decoder-Outlayer framework and the Vector Space Diversification Sampling method. This framework efficiently separates the pre-training and fine-tuning stages, while the sampling method employs pivot nodes to divide the subvector space and selectively choose unlabeled data, thereby reducing the reliance on human labeling. The pipeline offers numerous advantages, including rapid training, parallelization, buffer capability, flexibility, low GPU memory usage, and a sample method with nearly linear time complexity. Experimental results demonstrate that models trained with the proposed sampling algorithm generally outperform those trained with random sampling on small datasets. These characteristics make it a highly efficient and effective training approach for machine learning models. Further details can be found in the project repository on GitHub.

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
