Abstract

fetched live from OpenAlex

Compression plays an important role in social network analysis from both practical and theoretical points of view. Although there are a few pioneering studies on social network compression, they mainly focus on lossless approaches. In this paper, we tackle the novel problem of community preserving lossy compression of social networks. The trade-off between space and information preserved in a lossy compression presents an interesting angle for social network analysis, and, at the same time, makes the problem very challenging. We propose a sequence graph compression approach, discuss the design of objective functions towards community preservation, and present an interesting and practically effective greedy algorithm. Our experimental results on both real data sets and synthetic data sets demonstrate the promise of our method.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
