Abstract
The analysis of high-dimensional data often begins with the identification of lower dimensional subspaces. Principal component analysis (PCA) is a dimension reduction technique that identifies linear combinations of variables along which most variation occurs or which "reconstruct" the original variables the best. For example, many temperature readings may be taken in a production process when in fact there are just a few underlying variables driving the process. A problem with principal components is that the linear combinations can seem quite arbitrary. To make them more interpretable, we introduce constraints on the coefficients of the linear combination. Two classes of constraints are considered - those in which coefficients are equal to one of a small number of values (homogeneous constraints), and those in which many coefficients are set to 0 (sparsity constraints). The resultant interpretable directions may be calculated to be "close" to the original principal components, or...

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
