A Deep Graph Reinforcement Learning Model for Improving User Experience in Live Video Streaming [article]

Stefanos Antaris, Dimitrios Rafailidis, Sarunas Girdzijauskas
2021 arXiv   pre-print
In this paper we present a deep graph reinforcement learning model to predict and improve the user experience during a live video streaming event, orchestrated by an agent/tracker.  ...  Our experiments with three real-world datasets of live video streaming events demonstrate the superiority of the proposed model against several baseline strategies.  ...  DySAT 3 [33] a graph representation learning strategy that employs a multi-head self-attention mechanism to compute the graph's structural and temporal evolution.  ...

Meta-Reinforcement Learning via Buffering Graph Signatures for Live Video Streaming Events [article]

Stefanos Antaris, Dimitrios Rafailidis, Sarunas Girdzijauskas
2021 arXiv   pre-print
In this study, we present a meta-learning model to adapt the predictions of the network's capacity between viewers who participate in a live video streaming event.  ...  We evaluate the proposed model on the link weight prediction task on three real-world datasets of live video streaming events.  ...  To address this problem, large enterprises exploit distributed solutions provided by live video streaming companies e.g., Hive Streaming AB 1 .  ...
