How LingXi Achieves User‑Level QoE Optimization in Large‑Scale Adaptive Video Streaming
The paper “Towards User‑level QoE: Large‑scale Personalized Optimization of Adaptive Video Streaming” introduces LingXi, the first production‑grade system that deploys per‑user Bayesian optimization and Monte‑Carlo simulation to reduce video stalls and boost both QoE and QoS across millions of viewers, with especially strong gains for low‑bandwidth users.
