Larry Smarr | Director of the California Institute for Telecommunications and Information Technology (Calit2) | LinkedIn

Abstract: The human body is host to 100 trillion microorganisms, ten times the number of cells in the human body and these microbes contain 300 times the number of DNA genes that our human DNA does. The microbial component of our “superorganism” is comprised of hundreds of species with immense biodiversity. Thanks to the National Institutes of Health’s Human Microbiome Program researchers have been discovering the states of the human microbiome in health and disease. To put a more personal face on the “patient of the future,” I have been collecting massive amounts of data from my own body over the last ten years, which reveals detailed examples of the episodic evolution of this coupled immune-microbial system. An elaborate software pipeline, running on high performance computers, reveals the details of the microbial ecology and its genetic components. A variety of data science techniques are used to pull biomedical insights from this large data set. We can look forward to revolutionary changes in medical practice over the next decade.

Bio: Larry Smarr is the founding Director of the California Institute for Telecommunications and Information Technology (Calit2), a UC San Diego/UC Irvine partnership, and holds the Harry E. Gruber professorship in the Department of Computer Science and Engineering (CSE) of UCSD’s Jacobs School of Engineering. Before that he was the founding director of the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Champaign-Urbana. He is a member of the National Academy of Engineering, as well as a Fellow of the American Physical Society and the American Academy of Arts and Sciences.  In 2006 he received the IEEE Computer Society Tsutomu Kanai Award for his lifetime achievements in distributed computing systems and in 2014 the Golden Goose Award.  He served on the NASA Advisory Council to 4 NASA Administrators, was chair of the NASA Information Technology Infrastructure Committee and the NSF Advisory Committee on Cyberinfrastructure, a member of the DOE Advanced Scientific Computing Advisory Committee and ESnet Policy Board, and for 8 years he was a member of the NIH Advisory Committee to the NIH Director, serving 3 directors.

Point, Line & Data: New methods for understanding complex data, from storytelling to machine learning

Abstract: The aesthetics of science is changing, the diffusion of data visualization tools is enabling a revival of beauty in scientific research. More and more papers are presented with seductive images, convincing videos, and sharp interactive tools. Scientific storytelling will be discussed with 2 case studies: “Charting Culture, 2014”, and “Rise of partisanship, 2015”. In the second part of the talk we explore the connection between Machine Learning & Data Visualization. We will see together 3 projects: News Explorer – exploration of real-time news, Ted Watson – exploration of a large corpus of videos, and Watson 500 – the analysis of relationships between entities and topics in a specific corpus of date. We encourage the public to use these tools before the talk:

Quantifying, Visualizing, and Forecasting Global Human Society Through “Big Data”: What it Looks Like To Compute on the Entire Planet

Abstract: Put simply, the GDELT Project is a realtime index over global human society, inventorying the world’s events, emotions, and narratives as they happen. GDELT live machine translates the world’s information across 65 languages and identifies the planet’s events, counts, quotes, people, organizations, locations, millions of themes and thousands of emotions, imagery, video, and social posts, creating a massive realtime global graph. Here’s what it looks like to conduct data analytics at a truly planetary scale.

Machine Learning for Human Decision Making

Abstract: In many real-life settings human judges are making decisions and choosing among many alternatives: Medical doctor deciding a treatment for a patient, criminal court judge making a decision about a defendant, a crowd-worker labeling an image, and a student answering a multiple-choice question. Gaining insights into human decision making is important for determining the quality of individual decisions as well as identifying human mistakes and biases.

In this talk we discuss the question of developing machine learning methodology for estimating the quality of individual judges and obtaining diagnostic insights into how various judges decide on different kinds of items. We develop a series of increasingly powerful hierarchical Bayesian models, which infer latent groups of judges and items with the goal of obtaining insights into the underlying decision process. We apply our framework to a wide range of real-world domains, and demonstrate that our approach can accurately predict judge’s decisions, diagnose types of mistakes judges tend to make, and infer true labels of items.

Bio: Jure Leskovec is assistant professor of Computer Science at Stanford University and chief scientist at Pinterest. Computation over massive data is at the heart of his research and has applications in computer science, social sciences, economics, marketing, and healthcare.

Daniel Katz | Program Director in the Division of Advanced Cyberinfrastructure at the National Science Foundation

Scientific Software Challenges and Community Responses

Abstract: As the process of science has become increasingly digital, scientific outputs and products have grown beyond simple papers and books to include software, data, and other electronic components. Scientific knowledge is embedded in these components. And papers and books themselves are also becoming increasingly digital, allowing them to executable and reproducible. As we move towards this future where science is performed in and recorded as a variety of linked digital products, the characteristics and properties that developed for books and papers need to be applied to all digital products. This talk will discuss a number of the related challenges that face the computational and data scientific software community, including how researchers find software, how developers get credit for writing software, and how software can be sustained, many of which have parallels with data. It will also discuss how different members of the community are individually and collectively trying to address these challenges.

Biography: Daniel S. Katz is a Program Director in the Division of Advanced Cyberinfrastructure at the National Science Foundation. His interest is in the development and use of advanced cyberinfrastructure to solve challenging problems at multiple scales. His technical research interests are in applications, algorithms, fault tolerance, and programming in parallel and distributed computing, including HPC, Grid, Cloud, etc. He is also interested in policy issues, including citation and credit mechanisms and practices associated with software and data, organization and community practices for collaboration, and career paths for computing researchers. He received his B.S., M.S., and Ph.D degrees in Electrical Engineering from Northwestern University, Evanston, Illinois, in 1988, 1990, and 1994, respectively.

Understanding the Business Cases in Healthcare Delivery Systems for Data-driven Discovery​

Abstract: The US healthcare system is in the midst of transformative change in response to new payment models which transfer risk from traditional payers to providers, in order to better align incentives to support higher quality, lower cost and improved health outcomes. The most successful organizations will leverage insights from their operational and clinical data, using advanced analytical techniques, which will enable them to exceed in managing risk, providers, and patients. This talk will review business cases for data-driven discovery in the healthcare delivery models of tomorrow.

What data issues will these new organizations be facing? What are the new questions that need to be addressed? How will the use of data from EHRs, HIEs, and patient-derived data from the IoT change the way clinical medicine is practiced? How will data-driven discovery re-define our concept of personalized medicine?
