Abstract

fetched live from OpenAlex

In this paper, we explore image reconstruction from irregularly spaced samples using
\nnatural neighbour interpolation. We sample the image irregularly using techniques
\nbased on the Laplacian or the derivative in the direction of the gradient. Local
\ncoordinates based on the Voronoi diagram are used in natural neighbour interpolation to quantify the "neighbourliness" of data sites. Then we use natural neighbour
\ninterpolation in order to reconstruct the image. The main result is that the image
\nquality is always very good in the case of the sampling techniques based on the
\nLaplacian.

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.
