Speech: Distributed Applications Based on Mobile Cloud Computing and Software-Defined Networks
Abstract: We consider an emerging class of challenging networked multimedia applications called Real-Time Online Interactive Applications (ROIA). ROIA are networked applications connecting a potentially very high number of users who interact with the application and with each other in real time, i.e., a response to a user’s action happens virtually immediately. Typical representatives of ROIA are multiplayer online computer games, advanced simulation-based e-learning and serious gaming. All these applications are characterized by high performance and QoS requirements, such as: short response times to user inputs (about 0.1-1.5 s); frequent state updates (up to 100 Hz); large and frequently changing numbers of users in a single application instance (up to tens of thousands simultaneous users).
This talk will address two challenging aspects of future Internet-based ROIA applications: a) using Mobile Cloud Computing for allowing high application performance when a ROIA application is accessed from multiple mobile devices, and b) managing dynamic QoS requirements of ROIA applications by employing the emerging technology of Software-Defined Networking (SDN).

Speech: Small is beautiful: The quest for compact machine learning models
Abstract: Many machine learning models, such as deep networks, are powerful but computationally expensive. This often hinders deployment to small computing devices such as cell phones and the internet of things. In this talk, we consider two approaches to compress deep learning models so that the network size can be reduced without sacrificing performance. One is to quantize each full-precision weight to a small number of bits. This can be formulated as an optimization problem which is then solved efficiently by the proximal Newton algorithm. Besides greatly reducing the network size, this can also replace the underlying multiplications to simpler bit operations. The second approach is pruning, which resembles weakening of functional connections in biological brains. We show that the pruned sparse deep networks exhibit properties of the power law, which has been observed in the degree distributions of many biological networks. The power law is also naturally related to preferential attachment, and we propose a model to explain how the deep network topology evolves in continual learning.

Speech: Green Cloud Computing – Current Trends and Issues
Abstract: Cloud computing has emerged in the recent years as a promising paradigm that facilitates such new service models as Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). These services are becoming more common and require additional network and computing resources. In such paradigm, data centers play a crucial role as they provide the infrastructure for cloud services. Furthermore, data centers nowadays are specifically designed to be extremely over dimensioned in terms of number of servers, switching capacity and of number of deployed links and nodes to guarantee zero-loss and minimum latency packet forwarding. Recent surveys have shown that the energy consumption in a data center considerably contributes to its operation costs. A remarkable part of the large energy volume consumed in data centers today is due to the aforementioned over-provisioning to meet the stringent requirements on reliability. Therefore performance and energy issues are important factors for the design of large multi-tier data centers that can support multiple services.
The keynote is divided into two parts. In the first part of the talk, the motivations for current research activities on the areas of Green ICT are addressed. Recent hot research topics for energy-efficient networking, especially green data centers and clouds will also be discussed. In the second part, experiences and research results on the areas of Green Networking at the Future Internet research group (HUST) will be shared, including data center traffic measurement and modeling, energy profiling of network devices, energy-aware data center virtualization, energy-aware testbed, protocols and optimization algorithms.

Speech: Separable convolution for stereo visual matching network
Abstract: Recent work has exploited context information for finding correspondence in ill-posed regions. However current architectures rely on expensive computation to deal with ill-posed regions. To tackle this problem, we explore separable convolution and Atrous Spatial Pyramid Pooling in the application of the stereo match. The Atrous Spatial Pyramid Pooling model probes convolution features at multiple scales to take advantage of the capacity of global context information. 3D convolution was explored to learn context information while it spent expensive computation and occupy lots of GPU memory. Our proposed SCSMNet extends PSMNet by employing depthwise separable convolution with efficiently calculating and the modified ASPP model.

Speech: Smart System Controlling Traffic Lights based on Direction Priority
Abstract: One of causes of repeated traffic congestion at intersections in Hochiminh City is the unreasonableness of the current system controlling traffic lights that switches lights at fixedly programmed time points. In several cases, vehicles are compelled to stop at stop line while nothing travels on front intersection, and emergency vehicles can not overpass crowd of vehicles stopping before traffic lights. Moreover, the too slow movement of vehicles within intersection due to conflict of directions is also a cause of congestion and jam. This study proposes an approach, termed the approach to priority-based controlling traffic lights, to serving as a module of smart system controlling traffic lights. The approach eliminates the conflict of vehicles moving within intersection to decrease the time passing crossroad. Traffic lights are switched according to the priority of directions to reduce the thickness of vehicles before traffic lights of directions. As a result, the approach prevents congestion within intersection and behind traffic lights at flows entering crossroad.
