Hit Optimal Cache for Wireless Data Access
Bibliographic record
Abstract
One of the working requirements for many data access applications is the availability of the most updated information. In wireless communications service networks, remote data access consumes expensive wireless spectrum. An efficient cache can reduce the data access cost, by cutting down the amount of data transferred over the wireless channels. However, deploying an efficient cache in wireless environment is challenging, where caches are distributed all over the network and an update event invalidates all the cached copies of the updated data. In this paper, we formalize the concept of caching frequently accessed but infrequently updated data objects, and propose a cache replacement policy accordingly. To facilitate the replacement policy, two enhanced cache access policies are also proposed. The proposed caching policies are supported with strong theoretical analysis. We demonstrate that the policies guarantee an optimal number of cache hits in a caching system. Results from both analysis and our extensive simulations demonstrate that the proposed policies outperform the popular Least Frequently Used (LFU) scheme in terms of effective hits.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
