Tutorial 1: Network Mining and Analysis for Social Applications
Lecturer: Feida Zhu
Date: November 1, 2014, 13:20 – 15:20
Room: East Asia Hall, B/F
The recent blossom of social network and communication services in both public and corporate settings have generated a staggering amount of network data of all kinds. Unlike the bio-networks and the chemical compound graph data often used in traditional network mining and analysis, the new network data grown out of these social applications are characterized by their rich attributes, high heterogeneity, enormous sizes and complex patterns of various semantic meanings, all of which have posed significant research challenges to the graph/network mining community. In this tutorial, we aim to examine some recent advances in network mining and analysis for social applications, covering a di- verse collection of methodologies and applications from the perspectives of network patterns, relationship mining and identity linkage. We would present the problem setting, the research challenges, the recent research advances and some future directions for each perspective.
Feida Zhu is an assistant professor at the School of Information Systems of SingaporeManagement University (SMU). He has founded and managed as Academic Director the Pinnacle Lab a joint lab with China Ping An Insurance Group to focus on social media mining and analysis for finance innovation. He obtained his Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign (UIUC) in 2009. His current research interests include large-scale data mining, graph/network mining and social network analysis. His research on large-scale frequent pattern mining has won the Best Student Paper Awards at 2007 IEEE International Conference on Data Engineering (ICDE) and 2007 Pacific- Asia Conference on Knowledge Discovery and Data Mining (PAKDD).
Tutorial 2: Harvesting, Integrating, Maintaining and Leveraging Knowledge Graphs
Lecturer: Seung-won Hwang
Date: November 1, 2014, 15:40 – 17:40
Room: East Asia Hall, B/F
Knowledge graphs have served as an integral component of modern search engines and software in general. However, it is non-trivial to harvest, cleanse, and integrate web-scale knowledge graphs, which has been actively studied in diverse fields of computer science. This two-hour tutorial will cover recent work on broad issues of harvesting, integrating, maintain, and leveraging knowledge graphs.
Seung-won Hwang is an associate professor of computer science and engineering in POSTECH, Korea. Her recent research projects have been integrating multiple knowledge graphs for data-driven understanding of entities. Her recent findings have been published at database and NLP venues, including ACL, TKDE, TOIS, TODS, SIGMOD, VLDB, and ICDE.

|Title: BigData, AllData, Old Data: Predictive Analytics in a Changing Data Landscape
|Abstract:The landscape of the platform, access methodologies, shapes, and storage representations has changed dramatically. Much of the assumptions of a structured data world dominated by relational databases have been rendered obsolete. Today’s data analyst faces big challenges and a bewildering environment of technologies and challenges involving semi-structured and unstructured data with access methodologies that have almost no relation to the past. This talk will cover issues and challenges in how to make the benefits of advanced analytics fit within the application environment. The requirement for Real-time data streaming and in situ data mining is stronger than ever. We demonstrate how many of the critical problems remain open with much opportunity for innovative solutions to play a huge enabling role. This opportunity makes Data Science and several related fields critical to almost all future analytical tasks.

He was the industry’s first Chief Data Officer. Under his EVP role, Fayyad also founded and managed the Yahoo! Research Labs organization with offices around the world to develop the new sciences of the Internet, on-line marketing, Microeconomics, and algorithmic Advertising. At Yahoo! he applied Big Data techniques to content and advertising targeting and built the world’s largest group of data scientist – helping Yahoo! grow its revenues from user targeting by 20 times in 4 years. After Yahoo! and prior to Barclays he founded Open Insights, LLC a data strategy, technology and consulting firm based in Bellevue, WA to help enterprises understand data strategy and deploy data-driven solutions that effectively and dramatically grow revenue and competitive advantages.
In 2003 Fayyad co-founded and led the DMX Group, a data mining and data strategy consulting and technology company that was specializing in BigData Analytics major projects with some of the Fortune 500 clients. DMX Group was acquired by Yahoo! in 2004. In early 2000, he co-founded and served as CEO of Audience Science (digiMine, Inc.), a venture backed company addressing hosted business analytics and leading the market in targeted advertising.
From 1995 to 2000, Fayyad was at Microsoft in Redmond, WA where he led the data mining and exploration group at Microsoft Research and headed the data mining products group for Microsoft’s server division. From 1989 to 1996 Fayyad held a leadership role at NASA’s Jet Propulsion Laboratory (JPL), where his work in the analysis and exploration of Big Data in scientific applications gathered from observatories, remote-sensing platforms and spacecraft garnered him the top research excellence award that Caltech awards to JPL scientists – The Lew Allen Award for Excellence in Research, as well as a U.S. Government medal from NASA.
Fayyad earned his Ph.D. in engineering from the University of Michigan, Ann Arbor (1991), and also holds BSE’s in both electrical and computer engineering (1984); MSE in computer science and engineering (1986); and M.Sc. in mathematics (1989).

|Title: Relative thinking
|Abstract:The talk will present evidence showing that when people consider different sellers of the same good, or differentiated goods that differ in price and quality, they exhibit a decision-making bias of “relative thinking”: relative price differences affect them even when economic theory suggests that only absolute price differences should matter. This result is obtained in several experiments with different populations and different consumption categories. Sometimes subjects are affected only by relative price differences (“full relative thinking”) and sometimes also by absolute price differences (“partial relative thinking”). This behavior has implications for various research areas, including economic psychology, behavioral economics, judgment and decision making, marketing, consumer behavior, advertising, and industrial organization.

|Title: Monte Carlo Methods for Big Data and Big Models
|Abstract:Many quantitative problems in science, finance, and engineering are nowadays solved via Monte Carlo methods. Examples range from job scheduling and robot design in industrial engineering, chemical kinetics and charge transport in science, to option pricing and portfolio selection in economics and finance. Monte Carlo methods have dramatically changed the way in which statistics is used in today’s analysis of data, in particular in the presence of increasing complex data. In this talk I will explore how Monte Carlo methods can be used to effectively solve complicated sampling, estimation, and optimization problems. I will give examples of Monte Carlo methods for spatial data generation, charge transport simulation, and the construction of optimal tessellations.

|Title: Some Patterns in Online Behavior
|Abstract:In this talk we study patterns in online user behavior. We focus ontwo interesting cases: repeat consumption in online settings anddirections queries issued on maps. For repeat consumption, we analyzethe patterns by which a user consumes the same item repeatedly overtime, in wide variety domains ranging from check-ins at the samebusiness location to re-watches of the same video. We develop atemporal re-consumption model that depends on historical behavior andstudy its various properties. For direction queries, we focus on therestaurant-visiting process, where a user chooses one among severalalternatives. Here, we develop a spatial choice model that capturesthe interplay of the restaurant’s distance, rank, and the intrinsicrestaurant quality.
