Intelligent Video Coding by Data-driven Techniques and Learning Models
In June 6th 2016, Cisco released the White paper[1], VNI Forecast and Methodology 2015-2020, reported that 82 percent of Internet traffic will come from video applications such as video surveillance, content delivery network, so on by 2020. It also reported that Internet video surveillance traffic nearly doubled, Virtual reality traffic quadrupled, TV grew 50 percent and similar increases for other applications in 2015. The annual global traffic will first time exceed the zettabyte(ZB;1000 exabytes[EB]) threshold in 2016, and will reach 2.3 ZB by 2020. It implies that 1.886ZB belongs to video data. Thus, in order to relieve the burden on video storage, streaming and other video services, researchers from the video community have developed a series of video coding standards. Among them, the most up-to-date is the High Efficiency Video Coding(HEVC) or H.266 standard, which has successfully halved the coding bits of its predecessor, H.264/AVC, without significant increase in perceived distortion. With the rapid growth of network transmission capacity, enjoying high definition video applications anytime and anywhere with mobile display terminals will be a desirable feature in the near future. Due to the lack of hardware computing power and limited bandwidth, lower complexity and higher compression efficiency video coding scheme are still desired. For higher video compression performance, the key optimization problems, mainly decision making and resource allocation problem, shall be solved. In this talk, I will present the most recent research and new developments on deep neural network based video coding and its applications such as saliency detection, perceptual visual processing and others. This is very different from the traditional approaches in video coding. We hope applying these intelligent techniques to vide coding could allow us to go further and have more choices in trading off between cost and resources.

Strongly Stable System and Disturbance Reduction without Coprime Factorization
In linear control systems, it is important to construct a strongly stable system from the viewpoint of safety. In previous studies, we constructed strongly stable systems using coprime factorization and investigated their properties. For example, if the plant to be controlled is stable, a stable open-loop system can be constructed even if the feedback signal is interrupted. In this talk, we mainly show how to construct a strongly stable system without using coprime factorization, and also discuss how the degrees of freedom used in strongly stabilizing can be used to reduce disturbances.

Evolution and Application of Electric Power Robots for Inspection and Maintenance
To ensure the safe and steady running of power grid, many electric power robots have been increasingly developed and applied on the inspection and maintenance tasks for transmission lines, substation and distribution lines. This speech first delivers the state of art on electric power robots, which includes historical evolution, current status and challenges for the future. Following the overview, the challenges in robot mechanism design, control method and mechatronics systems will be discussed. Finally, three typical robots named as EPR-T, EPR-S and EPR-D respectively are introduced in detail. The EPR-T with a good locomotion and obstacle-crossing performance is designed to inspect extra high voltage (EHV) power transmission lines while EPR-S is designed for the inspection and replacement of faulty suspending insulators in substation. The EPR-D is developed for the hot-line work in distribution lines. A lot of field experiments have been carried out and experimental results show that these robots can reliably work during the complex and hazardous electric environment and possess the capability to implement a variety of inspection and operation tasks. The electric power robots have a broad application prospect in power grid inspection and maintenance.
