Seminar: Using semantic tables in XML query processing

Date: 20 Dec 2011 (Tuesday)
Time: 1pm - 2pm
Venue: 6th Floor Meeting Room, SA Block, FES, UTAR KL Campus, Kuala Lumpur.
Speaker: Prof. Dr. Ling Tok Wang, NUS, Singapore.
Title: Using semantic tables in XML query processing
Abstract: Processing a twig pattern query in XML document includes structural search and content search. Most existing algorithms only focus on structural search. They treat content nodes the same as element nodes during query processing with structural joins. Due to the high variety of contents, to mix content search and structural search suffers from management problem of contents and low performance. Another disadvantage is to find the actual values asked by a query, they have to rely on the original document. In this talk, we propose a novel algorithm Value Extraction with Relational Table (VERT) to overcome these limitations. The main technique of VERT is introducing relational tables to store document contents instead of treating them as nodes and labeling them. Tables in our algorithm are created based on semantic information of documents. As more semantics is captured, we can further optimize tables and queries to significantly enhance efficiency. Last, we show by experiments that besides solving different content problems, VERT also has superiority in performance of twig pattern query processing compared with existing algorithms.  We also extend VERT to process queries involving ID references or general queries with multiple join-linked twig patterns and queries involving grouping and aggregations.

Sciences Seminar Series

Date: 9 December 2011 (Friday)
Time: 11am - 12 pm
Venue: Level 6, West Room, SA block, UTAR Setapak Campus, Kuala Lumpur.
Speaker: Prof. Jeremy Levesley
Title: Radial Basis Function Approximation
===============================================================================

Dear all,

This week's DMAS & CMS talk will be on Friday, 11am-12pm. The speaker is Prof.
Jeremy Levesley from Department of Mathematics, University of Leicester, UK.


Abstract:
Radial basis functions have become an important tool for scattered data approximation, and theoretically can be used for approximation in
high dimensions. There is a very beautiful abstract theory of approximation involving so called native space (which I will not talk about). There is some interest in the finance industry in RBFs because of the possibility of high dimensional approximation and solution of partial differential equations. In this talk I will discuss some of the problems which arise with approximation with such functions, such as ill-conditioning and computation of full linear systems. I will offer some hope for the solution of these problems.

All are welcome.

Thank you very much.

Regards,
Event Committee.

Work Completion Seminar: New SIFT-based Calibration Methods for Hybrid Camera System


Dear all,

You are most welcome to attend the Work Completion Seminar by Mr Mr. Low Yi Qian (Master of Engineering Science), on his research title of New SIFT-based Calibration Methods for Hybrid Camera System. Details are as follow:

Date: 25/11/2011 (Fri)
Time: 11:00am-12:00noon
Venue: 5A meeting room, 5th floor, SA Block, FES, UTAR KL Campus.
Research title: New SIFT-based Calibration Methods for Hybrid Camera System
Candidate: Low Yi Qian
Abstract:
Multi-cameras networks have an important role in surveillance systems. In traditional cameras networks mainly based on static cameras. Static camera provides low resolution and poor image quality in modeling. At the meanwhile, Pan-Tilt-Zoom (PTZ) camera is able to obtain multi-angles of views and multi-resolution information; it provides more functionality compared with static camera. In multi-camera networks, they obtain two or more different perspectives views of scene to perform calibration within one another. Traditional approach to solve this problem is by using human inputs or referenced objects to find matched correspondences among all images. The recent works by some researchers have brought remarkable increase of automation to these problems. One of the main challenges in multi-cameras calibration is to obtain an accurate and fast estimation of disparities of two different views of scene. Besides disparities, differences might be caused by occlusion of the object, specular reflection, sensor noise and various other causes.
In this project, we designed and constructed a new hybrid camera system instead of using two static cameras. More precisely, our hybrid camera system consists of a static wide angle camera and a PTZ camera. Both cameras obtain different optical elements and resolutions. We proposed a master-slave concept to represent both cameras. A static camera is master camera with wide angle view is used to monitor the environment from a distance. The images taken from the master camera will be used as reference images. When the master camera detects an object of interest, the slave camera - PTZ camera, will zoom into the region of interest (ROI). PTZ camera plays an important role at pointing towards the ROI in high resolution as well as providing different parameters of PTZ values. Then, we studied and proposed calibration methods for the hybrid camera system. In particular, Scale Invariant Features Transform (SIFT) was used to identify keypoints to perform multiple views matching. One of the major contributions of this project is to design and develop a new smart filtering technique based on the principle of trigonometry, called Trigonometry Filter Technique (TFT). TFT is used to filter the false keypoints by calculating and classifying the orientation of the images. Furthermore, TFT also increases the determination and detection rate of ROI image localization. Secondly, we proposed a novel calibration method based on multiple-image stitching approach. By stitching images (by PTZ camera), a high resolution panorama image will be created. Finally, we are able to stitch and calibrate both static master camera and PTZ camera images without the use of any object as reference. By eliminating the use of reference objects, the obtained empirical results show good performance to handle images from various kinds of angles, scaled and target uncertainties.

Distinguished Lecturer is Prof Magdy Bayoumi.
Title: Wireless Sensors Networks: Current and Future Challenges
(Abstract)
Computers, communication, and sensing technologies are converging to change the way we live, interact, and conduct business. Wireless sensor networks reflect such convergence. These networks are based on collaborative efforts of a large number of sensor nodes. They should be low-cost, low-power, and multifunction. These nodes have the capabilities of sensing, data processing, and communicating. Sensor networks have a wide range of applications, from monitoring sensors in industrial facilities to control and management of energy applications to military and security fields. Because of the special features of these networks, new network technologies are needed for cost effective, low power, and reliable communication.
These network protocols and architectures should take into consideration the special features of sensor networks such as: the large number of nodes, their failure rate, limited power, high density, etc. In this talk the impact of wireless sensor networks will be addressed, several of the design and communication issues will be discussed, and a case study of a current project of using such networks in drilling and management off-shore oil and natural gas in the gulf region will be given.

Your attendance is highly appreciate.

Many thanks.

Talk #1: Service and Network Convergence in Next Generation Networks

Abstract: A common feature of contemporary wireless and wireline networks is that they provide access to or operate over IP-based networks. It is commonly agreed that next generation networks will consist of a conglomerate of access network technologies integrated by broadband IP-based core networks. Telecommunication service providers are taking advantage of the capabilities of next generation networks to offer a wide range of services to subscribers over a converged IP network regardless of the access technology.  Research and development efforts over the last few years have been focused on how to integrate and manage heterogeneous wireless/wireline access networks for a good service experience by subscribers. The presentation will review features and characteristics of converged access networks, describe the network and service architectures enabling access network convergence on the one hand and service convergence on the other, and discuss some of the technical issues that need to be addressed to provide a good service experience to subscribers. Novel solutions for selection of the best access network before connection establishment, and maintaining a connection across different access networks by vertical handoffs will be presented. Future research directions will be discussed.

 

 

Talk #2: Networking of Automobiles – Applications, Challenges and Some Recent Results

Abstract: Recent advances in wireless communication technologies are making it possible for automobiles to be integrated into the global network. Intelligent Transportation Systems with vehicles in the loop are expected to significantly improve road safety, reduce traffic congestion and cut greenhouse gas emissions. This is made possible in the USA by Dedicated Short Range Communications (DSRC), which employs the IEEE 802.11p standard over the 75MHz of spectrum in the 5.9 GHz band allocated by the FCC for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. DSRC is expected to revolutionize road transportation by making possible many real-time safety applications. However, global deployment of DSRC is not expected to materialize in the near term due to regulatory and financial challenges. In the meantime, vehicles and their passengers are increasingly equipped with different forms of wireless networking capabilities, e.g., cellular, WiFi and WiMAX. Thus there is also a growing interest in supporting applications like infotainment, travel advisory, route planning, etc., using heterogeneous wireless networks. In this presentation, I shall describe several applications that leverage the wireless communications to put vehicles in the loop. Different applicants impose different requirements on the wireless network for data routing, transfer latency, etc.  I shall review the technical challenges that need to be overcome to meet some of these requirements, and describe solutions developed in our recent research to meet these challenges. I shall conclude the presentation by discussing some future research directions.

CMS Seminar: Unfold the Secret of Multiplication (揭开乘法的神秘面纱)

==============================================================================
Department of Mathematical and Actuarial Sciences & Centre of Mathematical
Sciences Seminar Series

Date: 19 October 2011 (Wednesday)
Time: 2 - 3 pm
Venue: SD 102, FES, UTAR KL Campus, Setapak, Kuala Lumpur.
Speaker: Mr Chang Yun Fah
Title: Unfold the Secret of Multiplication (揭开乘法的神秘面纱)
===============================================================================

Dear all,

This week's DMAS & CMS talk will be on Wednesday, 2-3pm. The speaker is Mr Chang
Yun Fah from Department of Mathematical and Actuarial Sciences, UTAR.


Abstract:
对于许多学生来说,数学是一门深奥难懂的科目。面对一条条的数学公式和符号,学生们除了背死书之外就只能依靠重复练习和上补习课来补救。这种极尽痛苦的学习历程让很多学生对数学产生了焦虑。他们即使毕业后成为专业人士,但对数学的阴影终究是挥之不去。

追根究底,许多人对数学产生焦虑感多源自于数学抽象的概念和复杂的公式。但是数学教学的刻板与枯燥方式也成了捏杀学生的学习兴趣主凶之一。尤其是我国盛行的填鸭式教育,强调的是死背和重复练习已严重扭曲了因材施教的教育原则。此乃数学教育里必须去除的迷思之一。

我相信,数学的学习过程可以是生动有趣的,也并非一成不变。同样的一道数学题,往往可以有好几种的解答方式。而每一种方式都有其特征。要减少人们对数学的焦虑,就必须在教学中突出这些优美的特征,以轻松及生动的方式带出整个运算过程。

就以乘法(Multiplication)的运算为例子。许多人都是从熟背一至十二的乘法表开始,总共背诵了144个的方程式。但有多少人知道,其实我们的老祖宗比我们更聪明,他们只需要背诵78个就可以了。而如果我们懂得一些简单的数学公式,那我们要背诵的东西就会更少。

同样的道理,当孩子无法掌握学校教的那一套乘法时,老师和父母可以做些什么呢?继续强迫孩子死记硬背的把整套乘法,不管孩子能否消化;还是怒气冲冲地大骂孩子‘笨蛋’无可救药?师长们是否有想过用不同的乘法方式来教导孩子,也许效果会更好?请别把学校的那一套当作是唯一的和最好的标准。道理很简单;每个孩子好比不同的交通工具,如果是汽车,你总不能让它在水里游;换作是飞机,你也不能把它放到火车轨道行。

除了刻板的教学方式问题,近年来数学教育的发展也走向另一个让人担忧的方向,即越来越多的教育工作者和父母对快速计算(Fast Arithmetic)的迷思,总是希望孩子们能够在几秒内计算出类似题目的答案!答案正确还不够好,要‘快’才能进入神童榜。要清楚,快速计算只不过是把不同的技巧背熟再根据情况来运用而已,对于真正了解和掌握数学还差十万八千里。要快和准哪里需要这么辛苦每天拼命的练习,五支手指按一按计算机就可以了。再说,快速计算的高手也未必过得了高中数学考试,更别说成为数学家。相反地,这种讲究‘快速’的思维训练搞不好还会让孩子错过往扎实的基础下功夫。

今天的分享,不是也不可能改变以上所触及的两个数学教育的迷思。只是希望能提供一个不一样的选择让大家重新了解数学。我们会发现原来一个简单的乘法,可以有不同的演算方法;有的蛮有趣,有的很抽象,有的我明明会但从来没有好好地深入了解;有的那么容易为什么自己偏偏没想到。这种心情的起伏,能激发你更深入了解每一种方法背后的原理。

对于我来说,从今天的分享中学会多少种乘法并非最重要的。我更热切期望此分享能带来的启发:如学生们在学习课本上的东西后,自己是否能够创造出新方法和见解;老师们在教学上,能否加入一些新元素让教学更生动;父母们在亲子关系中,能否与孩子一同成长;及就业人士在工作岗位和人际关系上,是否能从不同的角度对待某件事物,而不再固执己见。 

All are welcome.

Thank you very much.

Regards,
Event Committee.

RAship on Brain Computer Interface

There is a vacancy for Research Assistant in FES, UTAR KL Campus. Please contact Prof Goh Sing Yau (gohsy@utar.edu.my) if anyone is interested.


People with locked-in syndrome/severe motor disabilities such as those afflicted with amyotrophic lateral sclerosis may be unable to communicate with the outside world. In an earlier project, the principal investigator and his colleagues have developed a Brain-Computer Interface (BCI) system to control a wheelchair using natural EEG oscillations generated by motor imagery. This method of using motor imagery is very safe, reliable and at the same time frees the mind to observe and plan future intensions while activating a wheelchair to move to the desired location.

However, for the purposes of communication such as writing a letter or communicating with another person, we will need a faster information transfer rate. This can be provided by a complementary BCI system that uses steady-state visual evoked potential (SSVEP). In such a system, the subject is required to look at objects (for example, that can denote the direction of movement of the curser) that oscillate at specific frequencies resulting in evoked potentials of the same frequencies that can be measured at certain locations on the scalp. The frequencies of the evoked potentials will determine the desired movement of the curser that can be used to select words in a predictive text system to form the desired phrases or sentences to communicate with the outside world.

The RA is required to participate in a research team to develop the software for the SSVEP BCI system and the predictive text algorithm and selection GUI for communication. An example of predictive text is commonly seen in hand phone sms features. O'Riordan et. al. investigated the text input methods for mobile phones. Predictive text can be complemented by "auto completion" or "auto tree" depending on context and structure of the sentence. Steffen Bickel et. al. investigates algorithms that enable the finding of meaningful subwords and phrases.

I have a personal website designed mainly for my undergraduate students but has a short description of our research. http://gohsingyau.webs.com/research.htm

CCIS Seminar: Robust Fitting and Model Selection in Computer Vision


Dear Colleagues,
Centre for Computing and Intelligent Systems (CCIS), Universiti Tunku Abdul Rahman (UTAR) will be organizing the following open seminar:

Date: 7 Oct 2011 (Friday)
Time: 11:30am-12.00pm
Venue: 6th Floor Meeting room, SA Block, FES,  UTAR, KL Campus, Jalan Genting Kelang, 53300 Kuala Lumpur
Speaker: Tat-Jun Chin
Title: Robust Fitting and Model Selection in Computer Vision
Abstract: One of the earliest examples of robust model fitting in Computer Vision is to detect lines and curves in images using the Hough Transform (Duda and Hart, 1972). Since then robust model fitting techniques have become part of the standard toolbox for Computer Vision researchers and practitioners, especially on geometry estimation problems where approaches like RANSAC dominate. Robustness is crucial in many cases as the data acquisition and preprocessing pipeline is inevitably imperfect, and this introduces outliers and noise into the data. A second important aspect is model selection, especially in the case of multiple structures, i.e. how many lines do we have in the image? Traditional model selection techniques dictate that the best model is the one that balances goodness of fit and model complexity. In this talk I will discuss ongoing work at The University of Adelaide to find new paradigms for robust model fitting and model selection. In particular I will report recently proposed methods that cast robust model fitting and model selection as statistical learning problems. These new methods offer the promise of more robustness and applicability to a wider range of problems.
Speaker Bio:
Dr Tat-Jun Chin is a Lecturer in the School of Computer Science at The University of Adelaide. He received his Ph.D. in Computer Systems Engineering from Monash University, and B.Eng in Mechatronics from the Universiti Teknologi Malaysia (UTM). Dr Chin's current research focusses on robust model fitting approaches for Computer Vision applications. In particular he is interested in searching for new paradigms for the fundamental underpinning of robust model fitting approaches, and to extend the applicability of robust model fitting approaches to a wider range of problems and operating conditions.


The seminar is open to all staff, students and public. Admission is free and no registration required. Please encourage your students / research counterparts to attend this seminar.

CCIS Seminar: Multimedia Forensics & Inverse Light Transport: Introduction and Open Problems

Dear Colleagues,
Centre for Computing and Intelligent Systems (CCIS), Universiti Tunku Abdul Rahman (UTAR) will be organizing the following open seminar:

Date: 7 Oct 2011 (Friday)
Time: 11:00am-11.30am
Venue: 6th Floor Meeting room, SA Block, FES,  UTAR, KL Campus, Jalan Genting Kelang, 53300 Kuala Lumpur
Speaker: Tian-Tsong Ng
Title: Multimedia Forensics & Inverse Light Transport: Introduction and Open Problems
Abstract: Multimedia forensics arises from a question as old as photography: When is seeing is believing. Today, images and videos are as commonly exchanged and shared as are text messages when Internet was first invented. Visual content has become inseparable from our daily communications and is increasingly used as personal records or evidence in courts of law. I will introduce multimedia forensics and describe the open problems awaiting answers.
I will also briefly talk about a different research topic in computer vision and graphics known as inverse light transport. Light transport is function that maps the light sources and the images. Inverse light transport can be considered a general framework for tackling low-level computer vision problems and the research is still at its infancy. I will introduce the related early works and the open problems.
Speaker Bio:
Tian-Tsong Ng is a research scientist in Institute for Infocomm Research, Singapore. He received his B.Eng in Electrical Engineering from University of Malaya in 1998, his M.Phil. in Signal Processing from Cambridge University in 2001 and his Ph.D. in Electrical Engineering from Columbia University in 2007. His research interest lies in computer vision, computer graphics and image forensics.

Title: Development of Job Matching Algorithm with Collective Learning Methods
Abstract:
Hiring or job match placing the wrong job seekers to the particular job posted by the employers is a costly mistake. As it is the key to keep the job site remain competitive. The classical online recruiting applications use only simple Boolean operations comparing the basic requirement information to generate the job matched results to job seekers. Therefore, it's often claimed to be irrelevant job matched or too many "hits" [1]. Job seekers must browse through a long list of job advertisements in a given query [2]. The problem of the classical method is about the data modelling. Job seekers need to fill up massive form-based basic requirement information. The data given is too subjective to define its importance. Hence, the matching may not be good. Besides, online recruiting application must be able to discover interesting jobs for recommendation. Job seekers are more likely excited to see a range of different job types in which really match his or her working profiles and own interests. This is the area addressed by this research described in this thesis. An investigation and development of a different method of job matching algorithm was undertaken. The primary objective of this research is to offer an intelligence job matching mechanism incorporated the relevant feedback approach. Real data (job title, job descriptions and job requirements of 3000 job advertisements) from Jobstreet will be pursued with detailed analysis for the validation of the proposed method.


Talk on High Impact Research on Cloud Computing By Professor Rajkumar Buyya


Please be informed that the Department of Computer System and Technology, Faculty of Computer Science and Information Technology, University of Malaya is organizing a seminar with the following details:


Date: 21 September 2011 (Wednesday)
Time: 10:00-11:00
Location: DK2, FCSIT, University of Malaya, Kuala Lumpur. [map]
Speaker: Professor Rajkumar Buyya, The University of Melbourne, Australia; CEO, Manjrasoft Pvt Ltd, Melbourne, Australia
Title: High Impact Research on Cloud Computing: The Next Revolution in Information Technology

All are welcome to the seminar.

====================
Abstract: Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision. Cloud computing is the most recent emerging paradigm promising to turn the vision of "computing utilities" into a reality.

Cloud computing has emerged as one of the buzzwords in the ICT industry. Several IT vendors are promising to offer storage, computation and application hosting services, and provide coverage in several continents, offering Service-Level Agreements (SLA) backed performance and uptime promises for their services. It delivers infrastructure, platform, and software (application) as services, which are made available as subscription-based services in a pay-as-you-go model to consumers.  The price that Cloud Service Providers charge can vary with time and the quality of service (QoS) expectations of consumers.

This talk (1) presents the 21st century vision of computing and identifies various IT paradigms promising to deliver the vision of computing utilities; (2) defines the architecture for creating market-oriented Clouds by leveraging technologies such as VMs; (3) provides thoughts on market-based resource management strategies that encompass both customer-driven service management and computational risk management to sustain SLA-oriented resource allocation; (4) presents Aneka, a software system for rapid development of Cloud applications and their deployment on private/public Clouds with resource provisioning driven by SLAs and user QoS requirements, (5) reports experimental results on deploying Cloud applications in engineering, gaming, and health care domains on private or public Clouds, and (6) concludes with the need for convergence of competing IT paradigms for delivering our 21st century vision along with pathways for future research.
