Detail of Program

1. Autonomous Vehicle in I2R
Speaker: Mr Boon Siew HAN, Institute for Infocomm Research

2. Machine learning for intelligent transportation systems
Speaker: Prof Justin Dauwels, School of Electrical & Electronic Engineering (EEE), Nanyang Technological University

Advanced sensing and surveillance technologies can collect traffic information from various sources with high temporal and spatial resolution. Recorded data is essential for many real-time applications related to traffic management systems. However, the volume of the data collected severely limits the scalability of these systems for large networks.

In this talk, we consider the problems of compression, estimation and prediction in the context of large and diverse networks. Although methods such as principal component analysis (PCA) can efficiently compress traffic data sets, the low-dimensional models created by these methods are not readily interpretable. In this study, we propose an alternative approach to compress the recorded data and enhance the scalability of traffic management systems. We compress the network by representing it in terms of a small subset of the road segments present in the network; this is achieved by applying column-based matrix decompositions (a.k.a. CX-decomposition). This formulation allows us to efficiently store collected data in an intuitive way. Furthermore, we utilize the compressed representation to estimate the current state of the network by collecting data from a small subset of road segments. Similarly, we perform traffic prediction for the whole network, by developing prediction models for only the representative subset of road segments. For the analysis, we consider a large network comprising 17,967 road segments in Singapore.

Numerical results show that our method can achieve competitive compression performance compared to PCA. Results further demonstrate significant reduction of the computational complexity of large-scale prediction. This work is in collaboration with Prof. Patrick Jaillet (MIT) and is funded by NRF through the SMART Future Mobility program.

3. Cyber-Physical Secure Electric Vehicle Charging System in Smart Grid

Speaker: Dr. Jianying ZHOU, Institute for Infocomm Research

Smart Grid is the modernization of the existing power grid using digital technology in order to derive a number of benefits such as energy efficiency, security and reliability of power supply, and integration of electricity generated from renewable sources. One of the anticipated applications of Smart Grid is the introduction of the plug-in Electric Vehicle (EV). We face two challenges in this application. One is the impact of potential peaks (either accidental or malicious) on Smart Grid caused by connecting so many new and very large appliances to the grid. Another challenge is finding a way to take advantage of these new sources of distributed power storage, such that grid operators can draw upon this new power supply when needed. This requires a secure and reliable communication infrastructure to support monitoring, control and management of the EV charging infrastructure in Smart Grid. In this talk, I will present the cybersecurity challenges for the EV ecosystem in Smart Gird, introduce the EV cybersecurity architecture, and demonstrate a cyber-physical secure EV charging system.

4. Positioning in an Urban Environment

Speaker: Dr. Chee Wei ANG, Institute for Infocomm Research

Multi-modal positioning can be used in GNSS-challenged environments such as urban canyons and indoors. Sensors such as accelerometer, gyroscope, magnetometer etc. are becoming inexpensive due to proliferation of smart-phones. By combining the measurements from these sensors with WIFI and cellular measurements, location information can be derived. Multi-modal positioning could thus become a feasible solution in complementing GNSS positioning. In this talk, we will present our work on integrating various sensors found on mobile devices to derive the location of the user.
