Abstract

fetched live from OpenAlex

The Hierarchically Distributed Tree (HD Tree) is a novel distributed data structure. The purpose of proposing this new data structure is for better maintaining data localities with exponentially expanding and extending rate, and at the same time adapting the hierarchical structure to the distributed environment. In HD Tree, the routing table size is determined by the system parameter k, the performance of all basic operations are bound by O(lg(n)). The add-on distributed structure in HD Tree generates multiple routes between any two nodes in the system, and the progressive routing in HD Tree can be conducted more strategically because of the global awareness about the location of each node. Operations in HD Tree can be designed highly error resilient, and the hierarchical nature in HD Tree makes load balancing straightforward, and it is massively scalable not only in multidimensional rang queries, but also in constructing and maintaining P2P overlay structures.

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.
