Title：The Visual Communication over Wireless Networks
The tradition radio access network is built on the specific hardware platform, now is evolving towards cloud computing platform. With the new mobile edge computing (MEC) architecture, the communication and computation is converging, which brings many new opportunities and challenges for visual communication. The introduction of edge cache can reduce unnecessary traffic load and improve latency in the wireless access networks. How to optimize the caching strategy which aims to maximize the successful transmission probability (STP) of the video contents at edge base stations (BSs) is an interesting problems. We try to develop a gradient based iterative algorithm to solve the general random caching strategy optimization problem. Furthermore, the visual communication produces big data traffics. It puts forward a huge challenge to the wireless networks, while its abundant information provides potential to improve the spectrum efficiency significantly. We investigate a novel data assisted communication of mobile image (DAC-Mobi) scheme, which utilizes a large amount of correlated (similar) images stored in the cloud to improve the spectrum efficiency and visual quality.

Title: Personalized Video Streaming Strategy
Abstract: Personalized service has become the trend of network-based multimedia applications. Generally, there are two primary and essential technical challenges: i) different users usually require diverse user experiences, and ii) the network environments may vary with the time and place as well. To resolve this dilemma, this work proposes a personalized multimedia streaming strategy by intelligently categorizing the user via the data mining and adaptively predicting the transmission fashion in real time via the reinforcement learning. Specifically, on one hand, a class-level joint user classification and data cleaning scheme is proposed by frequently updating the training processes. On the other hand, a neural network model is constructed by making use of the reinforcement learning. As such, the video rate in the future can react quickly through the neural network model even if in a dynamic environment. Moreover, the objective representation of user experience is modelled from the user class instead of user himself, and it is used as the incentive information to train and improve the above neural network model. Extensive results validate the efficiency of the proposed scheme.
