Intelligent Caching in Dense Small-Cell Networks with Limited External Resources
Bibliographic record
Abstract
A promising solution to alleviate the mobile traffic burden on the Internet is to cache the most popular content at the heterogeneous wireless network edge. However, due to the vast content stored at the remote server, and to cache effectively, it concerns the file popularity profile that may not be known by the network operators in advance. Therefore, online learning techniques are used to tackle the challenges brought by the unknown knowledge. We present an effective and efficient algorithm based on the stochastic combinatorial multi-armed bandits with locked-up slots to address the content caching problem. Our work particularly addresses the scenario where dense small cells with diverse user populations are deployed. Additionally, this network is only given limited external resources such as computational resource to learn the caching policies and wireless backhaul resource to refresh the caches. Our algorithm learns the caching policies online which is to decide which files to be cached sequentially. Despite sharing the limited external resources, the proposed algorithm guarantees the performance of each small cell to approach the optimum. Experiments are conducted to cross-validate the theorem presented in this work.

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.
