Abstract

fetched live from OpenAlex

We propose a method for the visualization of large graphs. Our approach is based on the calculation of a density function resulting from the application of a metric on the vertices of a graph. The density function is then filtered using a convolution, leading to a partition of the graph. The choice of an appropriate kernel for the convolution makes it possible to control the number of clusters, and their size. Our algorithm can be executed automatically, but the parameters can also be interactively fixed by the user. We applied the algorithm to the problem of legacy code extraction from inclusion relation of C++ source files and film sequence analysis. The metric used here is defined from Strahler numbers, which measure the "ramification" level of graph vertices.

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.

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.
