Abstract

fetched live from OpenAlex

Kernel supervised principal component analysis (KSPCA) is a computationally ecient supervised feature extraction method that can learn non-linear transformations. We start the study of the statistical properties of KSPCA, providing the rst bound on its sample complexity. This bound is dimension-independent, which justies the good performance of KSPCA on high-dimensional data. Another observation is that in the kernelized version, the number of parameters of KSPCA grows linearly with the sample size. While this potentially increases the risk of over-tting, KSPCA works well in practice. In this work, we justify this compelling characteristic of KSPCA by providing a guarantee indicating that KSPCA generalizes well even when the number of parameters is large, as long as they have small norms.

Full frame distilled prediction

Teacher imitation

Not 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.
