Abstract

fetched live from OpenAlex

A roof detection method using LiDAR data is proposed based on points' normal with weight.The normal of the plane,which is composed of point and its neighbor points,is counted to find out the high frequency,and the roofs are detected.Each point's weight is considered to determine the contribution to the plane which diminishes the affection of noises to some extent,and increases the accuracy of the small roof detection.In addition,multiple thresholds are adopted to detect roof planes with different sizes.Experiments are given to prove the algorithm proposed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
