Abstract

fetched live from OpenAlex

This paper presents a new method for point cloud simplification. The method searches for a subset of the original point cloud data such that the maximum geometric deviation between the original and simplified data sets is below a specified error bound. The underlying principle of the simplification process is to partition the original data set into piecewise point clusters and represent each cluster by a single point. By iteratively updating the partition and efficiently evaluating the resulting geometric deviations, the proposed method is able to yield a simplified point cloud that satisfies the error bound constraint and contains near minimum number of data points.

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.
