Large Scale Metric Learning using Locality Sensitive Hashing

     Tuesday June 14, 2016

keynote Speaker: Ramamohanarao Kotagiri
Professor in the Department of Computer Science and Software Engineering, Melbourne.

Abstract:  Metric learning tries discover mapping of features such that objects belonging a particular class each other in the new space. However, the current methods of discovering such matric mappings are computationally in feasible when the data set is huge with large number of features. My talk will describe the state of the art algorithms for metric learning. will present our recent work on an efficient approach for discovering metric learning based mappings using Locality Sensitive Hashing (LSH). Our generic approach can accelerate state-of- the-art metric learning while achieving competitive classification accuracy, expanding feasibility by an order of magnitude. Our approach can accelerate Large Margin Nearest Neighbour (LMNN) to learn metrics on 1,000,000 samples in 3.6 minutes which is reduced from 5.8 hours.

Transparent-Computing based Intelligent Terminals and Their Applications.

     Tuesday June 14, 2016

keynote Speaker: YaoXue Zhang
President of the Central South University, China,
Fellow of the Chinese Academy of Engineering,
Professor in the Department of Computer Science and Technology at Tsinghua University, China.

Abstract: Recently, intelligent terminals, such as wearable devices and self-service terminals, have played an important role in daily life. This is an area with tremendous growth, primarily due to mobile use cases of terminals. However, current systems of intelligent terminals were designed for dedicated applications, not for their coming dominant use as mobile service. Such systems are prone to high power consumption, safety and cross-platform issues. Transparent computing is a promising technology that solves the urgent problems of intelligent terminals. In this talk, I will review the designs of current system and describes how transparent computing technology significantly improves the progress of intelligent terminals. I will share result of our research and our experience of deploying transparent-computing based intelligent terminals in user (and real) environments. I will also provide a wish list for "sensor+ network" — a large platform based on Transparent-Computing for connecting mass terminals and enhancing their applications.

Abstract: Big Data processing concerns large-volume, growing data sets with multiple, heterogeneous, autonomous sources, and explores complex and evolving relationships among data objects. This talk starts with a HACE theorem ( that characterizes the features of the Big Data revolution, and presents BigKE, a big data knowledge engineering framework that handles fragmented knowledge modeling and online learning from multiple information sources, nonlinear fusion on fragmented knowledge, and automated demanddriven knowledge navigation. We discuss challenging issues and our ongoing research efforts with BigKE.

On Application-Aware Information Extraction for Big Data in Social Networks

Wednesday June 15, 2016
keynote Speaker: Ming-Syan Chen
Distinguished Professor and Dean, College of EECS, National Taiwan Univ.

Abstract: Due to the paradigm shift to the Cloud computing, data has been accumulated at fast pace in various applications. Among others, the number of social network activities is increasing drastically. It has become very desirable to conduct various analyses for applications on social networks. However, as the scale of a social network has become prohibitively large, it is infeasible to scrutinize the data and extract the key essence from the entire social network. This issue becomes further complicated due to the heterogeneous nature of the data. As a result, a significant amount of research effort has been elaborated upon extracting the essential application-dependent information from a social network. In this talk, we shall examine some recent studies on data processing and information extraction for social networks. Explicitly, we shall explore the methods for three levels of information extraction in a social network, namely, parameter extraction, information extraction, and structure extraction, and interpret them from their respective objectives. We then comment on how to conduct application-aware information extraction for big data in social networks.
