Abstract

fetched live from OpenAlex

Peer-to-peer systems can share the computing resources and services by directly communicating within a widely distributed network. It is important that these systems can efficiently locate, in as few hops as possible, the node storing the desired data in a large system. Thus, it is worth consuming some extra storage to obtain better routing performance. In this paper, we propose redundant strategies to improve the routing performance and data availability on Chord and De Bruijn topologies. Hybrid-Chord combines multiple chord rings and successors, and Redundant D2B maintains successors, to improve the routing performance. The proposed systems can reduce the number of lookup hops significantly (by as much as 50%) compared to the original ones, and have better fault tolerance capabilities, with a small storage overhead.

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.
