| Abstract(in English) | Improving user satisfaction is an important issue in providing video content delivery services over the network. The network control that considers the quality of experience (QoE) of users is effective to optimize the service performance from the user's point of view. Studies on QoE models using network quality and other factors have been carried out to estimate the QoE of users. However, since QoE is affected by not only network quality but also by human emotions and cognitive biases, a QoE model that includes human psychological effects is necessary. In recent years, quantum decision making has been attracting attention as a method to model cognitive biases. In this paper, we propose a QoE model that includes cognitive biases using quantum decision-making. Then, we simulate the QoE model using video data and show that the user's cognitive bias and its temporal change can be represented by the QoE model with quantum decision making. |
