Abstract

fetched live from OpenAlex

This paper looks at the network robustness problem from a new perspective. Inspired by Darwin's survival value, a graph-theoretical metric, betweenness, in combination with network weight matrix is used to define a global quantity, network criticality, to characterize the adaptability of a network to the changes in network conditions. We show that network criticality can be interpreted as the average cost of a journey between any two nodes of a network, or as the average of link betweenness sensitivity of a network. We investigate communication networks in particular, and show that in order to maximize the carried load of a network, one needs to minimize network criticality. We show that network criticality is a monotone decreasing and strictly convex function of weight matrix. This leads to a well-defined convex optimization problem to find the optimal weight matrix assignment. We investigate the solution of this optimization problem for the weight assignment and compare our results with existing methods.

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.
