Modeling User's Resolution Selection in Video Streaming by Quantum Decision Making
Tatsuya Otoshi, Masayuki Murata (Osaka Univ.) IN2017-123
Abstract (in Japanese) (See Japanese page) 
(in English) Various services including video streaming are provided via the Internet. In the future, as network virtualization technology advances, building and controlling a network for each service is expected to make the network suitable for the service. In this case, it is necessary to design the network construction and operation from the viewpoint of the quality of experience (QoE) of users. Although research on modeling QoE of users has been advanced, the QoE changes according to the user's psychological effect, so it can be difficult to model the complete QoE in the conventional model. On the other hand, quantum decision making has begun to be drawing attention in recent years as a model expressing human cognitive state and decision making. In quantum decision making, it is possible to represent human behavior, which is hard to express in the conventional cognitive model, and it is regarded as promising as a more general model. In this paper, we attempt to model user's behavior when viewing video streaming by the quantum decision making. Through simulation, we show that the tendency of video resolution selection caused by psychological effects of users can be modeled.
