Abstract

fetched live from OpenAlex

A novel anomaly detection idea is proposed to improve the detection result because of the complex background and the subpixel materials. Firstly,this method suppresses background using principal component analysis( PCA),secondly,it extracts the endmembers by the orthogonal subspace projection( OSP),and detection the targets using spectral angle mapping( SAM) at last. And the approach is better than other two methods by comparing the ROC of three detection methods.

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.
