Invited Talk 1: ”Providing Usability Support for Mobile Applications in a Vehicular Environment”
Dr. Kyungmin Lee, Facebook, USA

 
Abstract:
We live in a world where mobile computing systems are increasingly integrated with our day-to-day activities. Unlike the traditional desktop environment, people interact with mobile applications while performing other primary tasks such as walking and driving. As a result, developers can no longer assume mobile applications will always receive the user’s full attention. Furthermore, with the rise of wearable computing platforms such as Google Glass and smart watches, and with the deployment of pervasive platforms such as in-vehicle infotainment systems, the contention for available user attention will grow even more between mobile applications and the user’s primary activity.
One of the environments where the user has a limited amount of attention to interact with mobile applications is the vehicular environment. In this talk, I will present how I can provide system support for providing better usability in a vehicular environment. I will first discuss AMC (Android Model Checker), a toolkit that I have developed to assist application developers to automatically check their applications for vehicular UI guideline violations. Then, I will discuss my latest work, Gremlin, which requires the mobile OS to manage user attention in a vehicular setting. Gremlin ensures high usability of mobile applications since it only allows mobile applications to initiate an interaction when the user has sufficient amount of available attention to handle the interaction.

Invited Talk 2: ”Mobile Deep Learning Framework for Continuous Vision Sensing”
Prof. Youngki Lee, Singapore Management University, Singapore

 
Abstract:
The rapid emergence of head-mounted devices such as the Microsoft Hololens enables a wide variety of continuous vision applications. Such applications often adopt deep-learning algorithms such as CNN and RNN to extract rich contextual information from the first-person-view video streams. Despite the high accuracy, use of deep learning algorithms in mobile devices raises critical challenges, i.e., high processing latency and power consumption. In this talk, I am going to introduce our early efforts to build a mobile deep learning inference system named DeepMon. DeepMon runs a variety of deep learning inferences purely on a mobile device in a fast and energy-efficient manner. For this, we designed a suite of optimization techniques to efficiently offload convolutional layers to mobile GPUs and accelerate the processing; note that the convolutional layers are the common performance bottleneck of many deep learning models. Our experimental results show that DeepMon can classify an image over the VGG-VeryDeep-16 deep learning model in 644ms on Samsung Galaxy S7, taking an important step towards continuous vision without imposing any privacy concerns nor networking cost.

Invited Talk 3: ”Enabling Customized Data Management on Mobile Systems”
Prof. Steve Ko, University at Buffalo, USA

 
Abstract:
In this talk, I will discuss a pluggable data management solution for modern mobile platforms (e.g., Android) that my research group is working on. Our goal is to allow data management mechanisms and policies to be implemented independently of core app logic. Our design allows a user to install data management solutions as apps, install multiple such solutions on a single device, and choose a suitable solution each for one or more apps. It allows app developers to focus their effort on app logic and helps the developers of data management solutions to achieve wider deployability. Finally, it gives increased control of data management to the end users and allows them to use different solutions for different apps. I will discuss our prototype implementation called BlueMountain, as well as several data management solutions we have implemented for file and database management to demonstrate the utility and ease of using our design.

Invited Talk 1: ”Turbo Controller Area Network (Turbo CAN): Next Generation In-Vehicle Networking Supporting +100Mbps and Being Compatible with CAN”
Prof. Ji-Woong Choi, DGIST, Korea

 
Abstract:
As the number of electronic components in the car increases, the requirement for the higher data transmission scheme among them is on the sharp rise. The controller area network (CAN) has been widely adopted to support the in-vehicle communications needs but the data rate is far below what other schemes such as Ethernet and optical fibers can offer. A new scheme, named Turbo CAN, for enhancing the speed of CANs has been proposed recently, where a carrier modulated signal is introduced on top of the existing CAN signal, whereby the data rate can be enhanced over 100 Mbps. Turbo CAN is compatible with the existing CAN network and accordingly enables seamless upgrade of the existing network to support high-speed demand using CAN protocol and easier interfacing with vehicle to something (V2X) data. In this talk, I will briefly explain the trends of in-vehicle networks and introduce the main concept of Turbo CAN. Finally, its performance and backward compatibility are shown via analysis and computer simulations.

Invited Talk 3: ”V2X Channel Characteristics: Guidelines for Designing V2X Service Applications”
Prof. Dong Seog Han, KNU, Korea

 
Abstract:
Vehicle-to-X (V2X) communication is no longer future oriented technology because the USDOT NHTSA recently issued a Notice of Proposed Rulemaking (NPRM) to mandate vehicle-to-vehicle (V2V) communication technology for new light vehicles in the United States. Establishing V2X application services needs special attention since vehicular communication environments are represented by low antenna heights and high mobility of vehicles. Such characteristics make the vehicular channel propagation dynamics more complex and time-varying. Thus, extensive analysis of V2X channel characteristics is essential for designing service applications. In this talk, both the state-of-the-arts and open issues on V2X channel characteristics including field measurement campaign and data analysis will be introduced.

Invited Talk 1: ”A More Intuitive Way to Control IoT Devices in Proximity”
Prof. Kyunghan Lee, UNIST, Korea

 
Abstract:
Controlling IoT devices is typically considered easy, but there are situations where this conception is wrong. Those include the followings: 1) when initializing an IoT device, 2) when trying to control an IoT device which is initialized and registered by another person, and 3) when trying to control IoT devices of the same type. We identify the challenges involved in these situations and propose a new intuitive communication method. Our method lets a user device such as a smartphone pinpoint and activate an IoT device with the help of an IR transmitter and communicate with the pinpointed IoT device through the broadcast channel of WiFi. Thanks to its unique design, our method allows a user device to immediately give a command to a specific IoT device in proximity even when the IoT device is uninitialized, unregistered to the control interface of the user, or registered but physically undistinguishable from others. Our method implemented on Raspberry Pi 2 devices demonstrate that it indeed enables intuitive and responsive controlling of IoT devices. Our experimental study shows that its end-to-end delay for each successful commanding to an IoT device is upper bounded by 2.5 seconds and has its median at about 0.74 seconds.

Invited Talk 2: ”Calibrating Time-variant, Device-specific Phase Noise for COTS WiFi Devices”
Prof. Sangtae Ha, University of Colorado, USA

 
Abstract:
Current COTS WiFi based work on wireless motion sensing extracts human movements such as keystroking and hand motion mainly from amplitude training to classify different types of motions with training, as obtaining meaningful phase values is very challenging due to time-varying phase noises occurred with the movement. However, the methods based only on amplitude training are not very practical since their accuracy is not environment and location independent. This talk introduces a list of recent works on COTS WiFi based motion sensing and presents an effective phase noise calibration technique which can be broadly applicable to any COTS WiFi based sensing. We leverage the fact that multi-path for indoor environment contains certain static paths, such as reflections from wall or static furniture as well as dynamic paths due to human hand and arm movements. Our evaluation shows that calibrated phase values provide much rich, yet robust information on motion tracking — 70th percentile angle estimation error up to ten degrees, 80th percentile tracking error up to 15 cm, and its robustness to the environment and the speed of movement.

Invited Talk 1: ”5G Technology Overview”
Dr. Taeyoung Kim, Samsung Electronics, Korea

 
Abstract:
With the ever-increasing demands on mobile data traffic, stronger requirements on latency and reliability of novel mobile services, it becomes more challenging to meet those diverse needs by sheer migration of the existing cellular technologies. Consequently, 3GPP set out 5G standardization to accommodate those needs with evolutionary technologies in April 2016. This presentation introduces the candidate technologies to meet these diverse requirements and the progress of 3GPP standardization for 5G.
Samsung’s innovative and pioneering technologies are now being used in the most advanced 5G trials yet and are helping to lay the foundation of critical 5G standards. Through research partnerships spanning the industry value chain, Samsung and its global partners are now demonstrating the viability of some of the first practical use cases, including fixed wireless access.

Invited Talk 3: ”Programmable and Agile Wired Infrastructure for 5G”
Dr. Sueng Yong Park, Kulcloud, Korea

 
Abstract:
It is getting clear that the fifth generation (5G) wireless systems would bring a profound impact on the architecture of the modern communication infrastructure. The communication industry traditionally led the innovation by introducing the fast and convenient wireless and wired communication, paving a way to the modern information society. But, in recent years, the pace of such innovation is rather slowed and the communities are asking themselves if we can do better.
Very interestingly, the computer industry, in recent years, has been actively adopting the virtualization, SDN, software driven infrastructure, cloud computing and storage and other innovative infrastructure technologies. With the enhanced infrastructure, the industry has not only creatively broken the traditional business models but made the new and innovative models and is expanding market very quickly.
Proposals and new architectural models for 5G wireless systems are arguably the first pan-communication industry efforts to change the communication infrastructure from the base, making them as agile and programmable as those of computer industry. The scope of these works are too vast to cover in a short time. In this speech, we focus on the work in progress in the programmable and agile wired infrastructure, and study the impact of such new infrastructure on the business models of telecommunication industry.

Invited Talk 1: ”Gauging Variational Inference”
Prof. Jinwoo Shin, KAIST, Korea

 
Abstract:
Computing partition function is the most important statistical inference task arising in applications of Graphical Models (GM). Since it is computationally intractable, approximate methods have been used to resolve the issue in practice, where mean- field (MF) and belief propagation (BP) are arguably the most popular and successful approaches of a variational type. In this paper, we propose two new variational schemes, coined Gauged-MF (G-MF) and Gauged-BP (G-BP), improving MF and BP, respectively. Both provide lower bounds for the partition function by utilizing the so-called gauge transformation which modifies factors of GM while keeping the partition function invariant. Moreover, we prove that both G-MF and G-BP are exact for GMs with a single loop of a special structure, even though the bare MF and BP perform badly in this case. Our extensive experiments confirm that the newly proposed algorithms outperform and generalize MF and BP.

Invited Talk 2: ”From Big Data to Precision Oncology using Interpretable Machine Learning”
Prof. Su-In Lee, University of Washington, USA

 
Abstract:
While targeting key drivers of tumor progression (e.g., BCR/ABL, HER2, and BRAFV600E) has had a major impact in oncology, most patients with advanced cancer continue to receive drugs that do not work in concert with their specific biology. This is exemplified by acute myeloid leukemia (AML), a disease for which treatments and cure rates (in the range of 20%) have remained stagnant. Effectively deploying an ever-expanding array of cancer therapeutics holds great promise for improving these rates but requires methods to identify how drugs will affect specific patients. Cancers that appear pathologically similar often respond differently to the same drug regimens.
In this talk, I will present our on-going project on building a machine learning model that takes available molecular information, reasons about the best possible treatment strategy, and explains its reasoning. The most important step necessary to realize this goal is to identify robust molecular markers from available data to predict the response to each of hundreds of chemotherapy drugs. However, due to the high-dimensionality (i.e., the number of variables is much greater than the number of samples) along with potential biological or experimental confounders, it is an open challenge to identify robust biomarkers that are replicated across different studies. I will present two distinct machine learning techniques to resolve these challenges. These methods learn the low-dimensional features that are likely to represent important molecular events in the disease process in an unsupervised fashion, based on molecular profiles from multiple populations of patients with specific cancer type. I will present two applications of these two methods – AML and ovarian cancer. When the first method was applied to AML data in collaboration with UW Hematology and UW’s Center for Cancer Innovation, a novel molecular marker for topoisomerase inhibitors, widely used chemotherapy drugs in AML treatment, was revealed. The other method applied to ovarian cancer data led to a potential molecular driver for tumor-associated stroma, in collaboration with UW Pathology and UW Genome Sciences. Our methods are general computational frameworks and can be applied to many other diseases.

Invited Talk 1: ”UAVs and Their Potential in Delivering IoT Services”
Prof. Tarik Taleb, Aalto University, Finland

 
Abstract:
The usage of Unmanned Arial Vehicles (UAVs), simply known as drones, for mail delivery, rescue team management, or disaster recovery operations is gaining lots of attention. Along with the maturity of the technology and relevant regulations, a worldwide deployment of these UAVs is expected. Whilst these drones would be deployed for specific objectives (e.g., mail delivery), they can be simultaneously used for offering numerous Value-Added Services (VASs), particularly in the area of Internet of Things (IoT), when they are equipped with suitable and remotely controllable sensors, cameras, and actuators. Indeed, integrating and orchestrating the different segments of drones (i.e., each manufactured with specific hardware and used for a specific purpose) would yield a potential Unmanned Arial System (UAS) that could be used as an important data transport platform, on the fly and in parallel to the existing Internet system. Sharing the infrastructure of this UAS for the provisioning of different IoT services would lower both capital and operational expenses, would encourage innovation giving birth to a plethora of new IoT services that can be offered only from height, and would create a novel ecosystem with new stakeholders. The edification of this self-* multi-purpose UAS along with its VAS and its orchestration system comes with a number of scientific challenges, that this talk will tackle, introducing some potential solutions.

Invited Talk 2: ”Surprise AI — A Novel Approach for Self-Monitoring/Alerting Intelligent Drones (and Self-Driving Cars, too!)”
Dr. Bo Ryu, EpiSys Science, USA

 
Abstract:
The use of Artificial Intelligence and Machine Learning (AI&ML) for autonomous systems such as drones and self-driving cars is already an old news. While the AI&ML-based prediction and classification capability continues to impress the world, the uncomfortable truth is that it is not failure-proof. For emerging autonomous systems such as drones and self-driving cars, prediction/classification errors, however small, may lead to costly, and even fatal consequences. In this talk, we introduce “Surprise AI”, a powerful learning paradigm capable of monitoring Deep Learning models in operation during runtime. Surprise AI can detect input data that will likely lead to prediction/classification errors in real time. We demonstrate, via extensive testing with several DL models available in the public domain, that Surprise AI successfully detects, during runtime, whenever the DL model encounters an input data which contains feature(s) that deviate from the model with as high as 99% accuracy.

Invited Talk 3: ”UAV Management System Based on IoT Platform and U2X Networks”
Dr. Jaeho Kim, KETI, Korea

 
Abstract:
Recently, commercial Unmanned Aerial Vehicles (UAVs) called drones have received a lot of interest in the public and civil environments for their possibility as a potential enabler of promising services such as policing, peacekeeping, surveillance, product deliveries, aerial photography, and agriculture. However, in order to support those services smoothly, there is needed a stable and reliable UAV control and management system. Regarding this issue, common platforms and U2X (UAV-to-UAV, UAV-to-Infrastructure) networks are required to manage UAVs. This talk shall concentrate on the R&D activities for IoT-based UTM (Unmanned Aerial System Traffic Management) system and U2X networks such as cellular-based U2X and FANET(Flying Ad hoc Network). As a case study, this talk shall also introduce an implementation and demonstration for the IoT based drone management system.
