Abstract

fetched live from OpenAlex

Graph Neural Networks (GNNs), which gained popularity recently, is facing the problem of reducing the cost of acquiring large datasets.Although a portion of the work combining GNN with active learning has been moderately successful, there are still some shortcomings in this research area.Most of the studies using clustering methods can only obtain local optima, and some of them suffer from the problem of difficult convergence.Moreover, the result of clustering is often undesired if the amount of data in each class is not balanced.Some methods obtain higher performance by combining multiple metrics, but are limited by the adverse effects of under-training the initial network.For these reasons, we propose an active learning framework based on quadratic programming in this paper.This framework transforms the sample sampling process into an optimal solution problem, which can obtain the global optimal solution and avoid the problem of hard convergence.Experimental results on several datasets demonstrate that the proposed method outperforms other baselines.

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.
