Optimizing Adaptive Video Streaming in Mobile Networks via Online Learning

Theodoros Karagkioules, Georgios S. Paschos, Nikolaos Liakopoulos +3

In this paper, we propose a novel algorithm for video rate adaptation in HTTP Adaptive Streaming (HAS), based on online learning. The proposed algorithm, named Learn2Adapt (L2A), i…
