Abstract

fetched live from OpenAlex

In this paper, we propose a novel and efficient mobility extension based on a pro-active approach (i.e., the context transfer/caching occurs prior to the subscriber movement) with the objective to extend existing pub/sub systems to the mobile environments. We also describe the notion of neighbor graph, which forms the basis for pre-loading the subscriber context one hop ahead of its current location. We have investigated the adequacy of our proposed proactive approach in supporting mobile subscribers and compared its behavior with a durable subscription-based approach adapted by JMS-based pub/sub systems. The experimental results show that our pro-active approach reduces the message loss by more than 50% and the message duplication to zero compared to the durable subscription-based approach. It also achieves better throughput results with low cost in terms of mobility extension 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.

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.
