Abstract (in Japanese) (See Japanese page) 
(in English) To prevent the delivery of entire 360-degree (or 360) videos from adversely affecting QoE, tile-based viewport adaptive streaming that divides 360 video chunks into tiles and conveys streams with differentiated quality levels to viewport and non-viewport areas has been regarded as a promising solution.
Existing works have been devoted to the design of 1) viewport prediction (VPP) to predict users' viewport orientation due to head movements, and 2) tile bitrate selection (TBS) to determine tile-based bitrates for viewport and non-viewport areas. In this paper, we propose a system to leverage machine learning to tile-based viewport adaptive streaming for 360 videos. In particular, We apply long short term memory (LSTM) model to VPP, and use part of non-viewport areas to help resist prediction errors. In addition, We use real-world traces to train a TBS agent with reinforcement learning to determine tile bitrates for both viewport and non-viewport areas. The simulation results show that our system outperforms the existing scheme in various QoE metrics.
