Abstract

fetched live from OpenAlex

We investigate the effectiveness of spectral methods in clustering multi-scale data, which is data whose clusters are of various sizes and densities. We review existing spectral methods that are designed to handle multi-scale data and propose an alternative approach that is orthogonal to existing methods. We put forward the algorithm ROSC, which computes an affinity matrix that takes into account both objects' feature similarity and reachability similarity. We perform extensive experiments comparing ROSC against 9 other methods on both real and synthetic datasets. Our results show that ROSC performs very well against the competitors. In particular, it is very robust in that it consistently performs well over all the datasets tested. Also, it outperforms others by wide margins for datasets that are highly multi-scale.

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.
