Abstract
In this paper, a text classifier framework with a feature ranking scheme is proposed to extract social structures from text data. It is assumed that only a small subset of relations between the individuals in a community is known. With this assumption, the social network extraction is translated into a classification problem. The relations between two individuals are represented by merging their document vectors and the given relations are used as labels of training data. By this transformation, a text classifier such as Rocchio is used for learning the unknown relations. We show that there is a link between the intrinsic sparsity of social networks and class imbalance. Furthermore, we show that feature ranking methods usually fail in problem with unbalanced data. In order to deal with this deficiency and re-balance the unbalanced social data, a local feature ranking method, which is called reverse discrimination, is proposed.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
