TITLE: Maximizing Return and Minimizing Cost with the Right Decision Management Systems
SPEAKER: Rich Holada, Vice President, Predictive Analytics, IBM Software Group

ABSTRACT: The ability to achieve operational efficiency, product leadership and customer intimacy still eludes many organizations due, in large part, to the chaos of business. Inconsistent prioritization and decision making; poor visibility between systems; processes that are not well controlled; and individual front-line decisions that seem small but, in totality, have a huge impact make it difficult for organizations to link strategy to execution and back. During this presentation, we will demonstrate how automating and optimizing decisions (operational efficiency) with business rules and predictive models enables better data driven results across the enterprise, and how this is implemented at the point of impact (customer intimacy) to transform an organization and support market leadership.

TITLE: Semantic Search and a New Moore's Law Effect in Knowledge Engineering
SPEAKER: Wei-Ying Ma, Microsoft Research Asia

ABSTRACT: In history, Moore’s law has been used to describe the phenomenon of exponential improvement in technology - a virtuous cycle that makes technology improvement proportional to technology itself. For example, chip performance had doubled every 18-24 months because better processors support the development of better layout tools, which in turn support the development of even better processors. In this talk, I will describe a new Moore’s law that is being created in knowledge engineering and it is driven by the self-reinforcing nature of three trends and technical advancements: big data, machine learning, and crowdsourcing. I will explain how we can take advantage of this new effect to develop a new generation of semantic and knowledge-based search engines. Specifically, my presentation will cover three areas. The first area is knowledge acquisition, in which our goal is to build large and comprehensive entity and knowledge graphs to complement the web and social graphs. In support of this goal, I will introduce techniques for entity extraction and knowledgebase construction through interactive mining and crowdsourcing. The second area is knowledge management, in which our goal is to support advanced analytical queries by combining probabilistic knowledge with a distributed platform. The final area is knowledge-empowered search and applications, in which our goal is to use the knowledge we have acquired and curated to enable a wealth of applications. As the culmination of this work, I will show how we are now able to understand search queries, enable new entity-centric search experiences, and provide direct answers to natural language queries.

TITLE: Key Lessons Learned Building Recommender Systems for Large-Scale Social Networks
SPEAKER: Christian Posse, LinkedIn

ABSTRACT: By helping members to connect, discover and share relevant content or find a new career opportunity, recommender systems have become a critical component of user growth and engagement for social networks. The multidimensional nature of engagement and diversity of members on large-scale social networks have generated new infrastructure and modeling challenges and opportunities in the development, deployment and operation of recommender systems.
This presentation will address some of these issues, focusing on the modeling side for which new research is much needed while describing a recommendation platform that enables real-time recommendation updates at scale as well as batch computations, and cross-leverage between different product recommendations. Topics covered on the modeling side will include optimizing for multiple competing objectives, solving contradicting business goals, modeling user intent and interest to maximize placement and timeliness of the recommendations, utility metrics beyond CTR that leverage both real-time tracking of explicit and implicit user feedback, gathering training data for new product recommendations, virility preserving online testing and virtual profiling.

TITLE: Ensembles and Model Delivery for Tax Compliance
SPEAKER: Graham Williams, Director of Data Mining, Australian Taxation Office

ABSTRACT: Revenue authorities characteristically have a large store of historic audit data, with outcomes, ready for analysis. The Australian Taxation Office established one of the largest data mining teams in Australia in 2004 as a foundation to becoming a knowledge-based organisation. Today, every tax return lodged in Australia is risk assessed by one or more models developed through data mining, generally based on historic data. We observe that any of the traditional modelling approaches, particularly including random forests, generally deliver similar models in terms of accuracy. We take advantage of combining different model types and modelling approaches for risk scoring, and in particular report on recent research that increases the diversity of trees that make up a random forest. We also review, in a practical context, how such models are evaluated and delivered.

Dr Graham Williams is Director of Data Mining at the Australian Taxation Office, and previously Principal Computer Scientist for Data Mining with CSIRO. He is a Senior International Expert and Visiting Professor of the Chinese Academy of Sciences at the Shenzhen Institutes of Advanced Technologies, and Adjunct Professor in Data Mining, Fraud Prevention, Security, at the University of Canberra and Australian National University.

TITLE: Leveraging Predictive Modeling to Reduce Signal Theft in a Multi-Service Organization Environment
SPEAKER: Seymour Douglas, Director, Analytic & Forensic Technology, Deloitte Financial Advisory Services LLP

ABSTRACT: Signal theft can be defined as the interdiction, consumption or usage of carrier signal from a provider’s network without payment or payment of an amount less than the level of service consumed. High levels of signal theft can potentially reflect open technical network issues, failure of electronic countermeasures or operational gaps that are estimated to cost the cable industry providers more than$5 billion annually. This session will discuss the business challenges associated with the quantification of signal theft-related losses, outline some of the countermeasures taken by MSOs, and then provide views on the development of predictive models to help identify the potential likelihood of signal theft in a given environment. We will examine the performance of certain machine learning algorithms as well as data challenges associated with both the architecture construction and analytical efforts, and conclude with a lessons-learned discussion and views on future approaches.

TITLE: Experiences and Lessons in Developing Industry-Strength Machine Learning and Data Mining Software
SPEAKER: Chih-Jen Lin, National Taiwan University and eBay Research Labs

ABSTRACT: Traditionally academic machine learning and data mining researchers focus on proposing new algorithms. The task of implementing these methods is often left to companies that are developing software packages. However, the gap between the two sides has caused some problems. First, the practical deployment of new algorithms still involves some challenging issues that need to be studied by researchers. Second, without further investigation after publishing their papers, researchers have neither opportunity to touch real problems nor see how their methods are used. In this talk, we discuss the experiences in developing two machine learning packages LIBSVM and LIBLINEAR, which have been widely used in both academia and industry. We demonstrate that the interaction with users leads us to identify some important research problems. For example, the decision to study and then support multi-class SVM was essential in the early stage of developing LIBSVM. The birth of LIBLINEAR was driven by the need to classify large-scale documents in Internet companies. For fast training of large-scale problems, we had to create new algorithms other than those used in LIBSVM for kernel SVM. We present some practical use of LIBLINEAR for Internet applications. Finally, we give lessons learned and future perspectives for developing industry-strength machine learning and data mining software.

Chih-Jen Lin is currently a distinguished professor at the Department of Computer Science, National Taiwan University and a visiting principal research scientist at eBay Research Labs. He obtained his B.S. degree from National Taiwan University in 1993 and Ph.D. degree from University of Michigan in 1998. His major research areas include machine learning, data mining, and numerical optimization.

Chih-Jen Lin is best known for his work on support vector machines (SVM) for data classification. His software LIBSVM is one of the most widely used and cited SVM packages. Nearly all major companies apply his software for classification and regression applications. More recently, his team developed the software LIBLINEAR for large-scale document classification. This package has quickly gained attention as Internet companies routinely use it for their applications.

Chih-Jen Lin has received many awards for his research work. A recent one is the ACM KDD 2010 best paper award. He is an IEEE fellow and an ACM distinguished scientist for his contribution to machine learning algorithms and software design. More information about him can be found at

TITLE: Leveraging Data Mining to improve healthcare
SPEAKER: Bharat R Rao, Head, Center for Innovations Siemens Health Services

Healthcare is undergoing a dramatic transformation, from an inefficient, costly, reactive and ad-hoc model of care delivery to a more efficient, outcomes-based, proactive and knowledge-driven model that aims to control sky-rocketing costs and improve patient outcomes. While the recent drive to record patient data in electronic health records (EHRs) will provide the foundation for this transformation, data mining of the EHRs will play a critical role in achieving these goals.
In this talk, we describe three major areas of healthcare where data mining has helped support marked improvements in healthcare.  These include: mining medical images to help physicians detect medical abnormalities (e.g. cancer); mining the EHR for automated measurement of quality and compliance to the standard a care (an essential step for improving care); and rapid learning systems that mine large numbers of EMRs to discover key predictors of disease risk and outcome, and support personalized therapy recommendations.  We will also discuss some emerging healthcare data mining challenges in the areas of population management and social networking, as healthcare changes from a (patient-) visit-centered model to a patient-centered model of care.

Bharat Rao, PhD is Senior Director and Head of the newly-formed Center for Innovations for Siemens Health Services, based in Malvern, PA.
