Abstract

fetched live from OpenAlex

Fog-based Content Delivery Networks (CDNs) distribute contents from origin servers to cloud replica servers and to fog caches. Some of these fog caches may be located on Set-top Boxes (STBs) close to end users, assuming that the STBs can host micro-caches. This can greatly reduce Latency. Network function virtualization (NFV) is a technology that can be used in fog systems. NFV-enabled STBs can therefore host micro-caches implemented as virtual network functions (VNFs). Appropriate placement mechanisms are needed to place these micro-caches to improve end-users' QoS in terms of Latency while still minimizing cost. In this paper, this placement problem is modeled as an optimization problem. A bee colony-based algorithm is suggested to find the placement that minimizes an aggregation of Latency and micro-cache storage cost. The simulation results show an improvement in the aggregated Latency and cost when the proposed algorithm is deployed.

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.
