Date-Driven Computing for Smart Vehicles

Dr. Yajun Ha, ShanghaiTech University, China

Organized by IEEE Circuits and Systems Singapore Chapter

Date : 9 February 2017 (Thursday)
Time : 2.00 PM - 3.00 PM
Venue : Executive Seminar Room (S2.2-B2-53)

Abstract

Smart vehicles have been considered as an effective solution to many challenges in road traffic systems, for example lower accident rate, lower energy consumption per hundred kilometer, lower pollution and so on. As a result, this field has become a hot competition area for all major IT and vehicle manufactures in the recent years. However, there are still substantial technical and non-technical challenges ahead before smart vehicles, especially highly autonomous vehicles can be widely deployed in the mass market. In this talk, we focus on the general smart vehicle introduction, and the technical challenges, and the data-driven computing for smart vehicles. For the data-driven computing part, we will discuss a learning based approach for smart vehicles. This includes the sensor system for data collection, dataset preparation, learning from dataset, acceleration for data-driven computing and some application demonstrations.

An Anatomy of Social Media Popularity

Dr. Lexing Xie, Associate Professor, Australian National University, Australia

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

"Sponsored by the IEEE Circuits and Systems Society under its Distinguished Lecturer Program"

Date : 23 May 2017 (Tuesday)
Time : 2.30 PM - 3.30 PM
Venue : Executive Seminar Room S2.2-B2-53

Abstract

Lexing Xie75How did a video go viral? Or will it go viral, and when? These are some of the most intriguing yet difficult questions in social media analysis. This talk will first provide a broad overview of recent research in understanding the predicting popularity, driven by larger amounts of online data and more understanding of human perception and psychology.  I will then cover a few recent results from my group on understanding and predicting popularity, especially for YouTube videos. I will start by describing a unique longitudinal measurement study on video popularity history, and introduce popularity phases, a novel way to describe the evolution of popularity over time. I will then discuss a physics-inspired stochastic model that connects exogenous stimuli and endogenous responses to explain and forecast popularity. With such novel representation and new models, we can correlate video content type to popularity patterns, make better predictions, describe the endo-exo factors driving popularity, and forecast the effects of promotion campaigns.

Circuit Level Optimization of Fixed-coefficient Digital FIR Filters

Dr. Yajun Yu, Associate Professor, South University of Science and Technology, Shenzhen, China

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

Date : 27 June 2017 (Tuesday)
Time : 10.30 AM - 11.30 AM
Venue : Meeting Room B2 (S2-B2b-77)

Abstract

Digital finite impulse response (FIR) filter is one of the most important building blocks in many digital signal processing (DSP) circuits and systems. For very large scale integration (VLSI) implementation of fixed-coefficient FIR filters, the resource-hungry multipliers can be realized by a multiple constant multiplication (MCM) block using shift and add/subtract operations. The products generated by the MCM block are then delayed and accumulated using the product accumulation block. In this talk, the circuit level optimization of FIR filters, in particular the MCM block and product accumulation block, and their efficient VLSI implementation are discussed.

Rate-Distortion Optimization for Sparse Coding in Image Compression

Prof. Nam Ling

IEEE Fellow, IET Fellow

Sanfilippo Family Chair Professor

Chair, Department of Computer Engineering

Santa Clara University, U.S.A.

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

Date : 10 August 2017 (Thursday)
Time : 03.00 PM - 04.00 PM
Venue : Executive Seminar Room (S2.2-B2-53)

Abstract

Ling 5Traditional video and image compression in main stream standards such as H.264/AVC and H.265/HEVC adopt a hybrid coding method incorporating orthogonal transforms, motion estimation, intra prediction, and entropy coding. Such methods seem to have approached saturation on coding efficiency, and major breakthrough is hard to achieve by traditional signal processing techniques. Recently, much research has been focusing on applying machine learning approaches aiming to improve coding efficiency to another level. In this talk, we will give an overview of image/video coding and its recent progress; we will then focus on one of our group’s research using sparse coding with over-complete representation to reduce the number of coefficients representing image information, as opposed to those by a traditional discrete cosine transform (DCT) method. Dictionary with over-complete representation can be learned from data and trained by a K-SVD (singular value decomposition) algorithm. Orthogonal matching pursuit (OMP) algorithm is then applied to select dictionary elements and their coefficients to represent the image. We propose a rate-distortion optimization (RDO) approach to select the number of non-zero coefficients given a sparsity constraint. Experimental results demonstrated a very good improvement of coding efficiency by our approach over the conventional DCT-based scheme. Finally, we will highlight some of our current research.

Challenges and Opportunities of Circuits and Systems on Internet of Things

Dr. Yen-Kuang Chen

Intel Corporation, U.S.A.

IEEE Fellow

Editor-in-Chief of IEEE Journal on Emerging and Selected Topics in Circuits and Systems

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

"Sponsored by the IEEE Circuits and Systems Society under its Distinguished Lecturer Program"

Date : 18 August 2017 (Friday)
Time : 10.30 AM - 11.30 AM
Venue : Executive Seminar Room S2.2-B2-53

Abstract

This seminar aims to discuss the technical trends and challenges of circuits and systems on Internet of Things. Rapid advancement of networking technologies together with extreme miniaturization of computing and communication devices enable a host of new and exciting applications and services that connect the physical and the computational worlds. In the future, digital sensing, communication, and processing capabilities will be ubiquitously embedded into everyday objects, turning them into the Internet of Things (IoT). In this new paradigm, smart devices will collect data, relay the information or context to each another, and process the information collaboratively using cloud computing and similar technologies. This paradigm shift creates numerous challenges and opportunities for engineering. For example, in the future, enormous numbers of sensors will be deployed. The costs of servicing such sensors will be a major concern. It is often almost impossible to replace sensor batteries once they are in the field. Therefore, one major challenge is low power sensor design, or designs which do not require a battery change over the lifetime of the sensor. For example, if a sensor is deployed on an animal for tracking purposes, the battery of the sensor should outlive the animal. This creates a demand for energy-efficient designs. This seminar will discuss the challenges and opportunities of circuits and systems on Internet of Things.
