Shan Shan Huang

Shan Shan Huang, VP Product Management, LogicBlox, Inc.

As the VP of Product Management at LogicBlox, Shan Shan works on bringing to market a database technology that enables “smart applications”: applications that perform complex and often predictive analysis over a combination of large historical data sets and real-time feeds.

Abstract summary:

LogicBlox’s mission is to simplify the way we store, process, analyze, and present data in order to build interactive and data intensive applications. The typical application infrastructure today involve a variety of specialized data storage systems, integrated together with ETL tools. The increasing interest in applying machine learning and prescriptive methods to data is adding even more tools — and more integration layers — into this infrastructure. Integration drives up fragility. Integration drives down developer productivity and application performance. LogicBlox tackles this problem from the database angle, by building a unifying database that is capable of handling a wide variety of query workloads: graph, multi-dimensional analytics, and transactional updates. For the right type of applications, LogicBlox can replace a number of specialized databases and the need to integrate them together. In this talk, we discuss some key insights and principles behind the LogicBlox database, as well as its relevance to the data science community.

Abstract summary:

There is more data than ever in the world today. The sheer amount of data being collected is tremendous and coupled with complexity, has made it almost impossible for current tools and approaches to easily manage. Query-based approaches will reach their limits rather quickly because it is impossible to think of every possible query needed to extract information from such complex data. We cannot query what we don’t know!

Samantha Kleinberg

Samantha Kleinberg, Computer Science department, Stevens Institute of Technology

Samantha Kleinberg is an Assistant Professor in the Computer Science departmentat Stevens Institute of Technology.After completing her PhD in Computer Science in 2010 at NYU, she spent two years as a postdoctoral Computing Innovation Fellow at Columbia University, in the Department of Biomedical Informatics. Before that, Ms Kleinberg was an undergraduate at NYU in Computer Science and Physics. Ms Kleinberg’s book, Causality, Probability, and Time, is now available in print and electronically.

Abstract summary:

One of the key problems we face with the accumulation of massive datasets (such as electronic health records and stock market data) is the transformation of data to actionable knowledge. In order to use the information gained from analyzing these data to intervene to, say, treat patients or create new fiscal policies, we need to know that the relationships we have inferred are causal. Further, we need to know the time over which the relationship takes place in order to know when to intervene. However, these observational data are often noisy and prone to missing values. In this talk I discuss methods for directly incorporating data uncertainty into the inference process and show how this can be applied to mobile sensor data from people with diabetes.
