2nd Workshop on Data Mining for Medicine and HealthcareMay 4, 2013, Austin, TexasTo be held in conjunction with 13th SIAM International Conference on Data Mining (SDM 2013)
OverviewIn virtually every country, the cost of healthcare is increasing more rapidly than the willingness and the ability to pay for it. At the same time, more and more data is being captured around healthcare processes in the form of Electronic Health Records (EHR), health insurance claims, medical imaging databases, disease registries, spontaneous reporting sites, and clinical trials. As a result, data mining has become critical to the healthcare world. On the one hand, EHR offers the data that gets data miners excited, however on the other hand, is accompanied with challenges such as 1) the unavailability of large sources of data to academic researchers, and 2) limited access to data-mining experts. Healthcare entities are reluctant to release their internal data to academic researchers and in most cases there is limited interaction between industry practitioners and academic researchers working on related problems. The objectives of this workshop are:
Topics of InterestIn addition to the more classical data mining approaches, this workshop aims to include two new topic fields – i.e. visual analytics and text mining in medicine and healthcare. By this extension, we aim to foster interactions among multiple communities that work at the intersections of data mining, medicine and healthcare. Topic areas for the workshop include (but are not limited to) the following:

Abstract: Big Data and Patient-centered Healthcare Proactive personalized medicine is expected to bring fundamental changes, offering recommendations of lifestyle adjustments and treatments to avoid diseases a patient has high risk for developing in the future. No matter how unique our medical experiences, chances are that other patients among millions have experienced genetic and environmental risk factors that closely mirror ours. These medical experiences, risks, symptoms are tapped in the vast repositories of electronic medical records. Can we then take a data-driven approach to discover nuggets of knowledge and insight from the Big Data in healthcare for patient-centered outcomes and personalized healthcare? Can we answer the question: What are my disease risks? This talk will focus on our work that takes the data and networks driven thinking to personalized healthcare and patient-centered outcomes.

Abstract: Predictive Modeling of Large Healthcare Data under Privacy Constraints As medical records move to the digital age and the bedside gets increasingly instrumented, a wealth of information is being acquired, with the potential of providing unprecedented insights into the cause, prevention, treatment and management of illness. Analyses of such data also promises numerous opportunities for much more effective and efficient delivery of healthcare. However (valid) privacy concerns and restrictions pose a major impediment to realizing this potential. In this talk I will outline two approaches that we have recently and successfully taken that provide privacy-aware predictive modeling with little degradation in model quality despite restrictions on what can be shared or analyzed. The first approach focuses on extracting predictive value from data that has been aggregated at various levels due to privacy concerns, while the second introduces a novel, non-parametric Gibbs sampler that can generate "realistic but not real" data given a dataset that cannot be shared as is. [Joint work with Yubin Park and Shankar Mallikarjun] Marc Suchard, University of California, Los Angeles Bio: Marc A. Suchard is Professor in the Departments of Biostatistics, of Biomathematics and of Human Genetics in the UCLA School of Public Health and David Geffen School of Medicine at UCLA. He earned his Ph.D in biomathematics from UCLA in 2002 and continued for a MD degree which he received in 2004. Dr. Suchard is a leading Bayesian statistician who focuses on inference of stochastic processes in genomics and for massive datasets in healthcare. His training in both Medicine and Applied Probability help bridge the gap of understanding between statistical theory and clinical practicality. He has been awarded several prestigious statistical awards such as the 2003 Savage Award, the 2006 and 2011 Mitchell Prizes, as well as a 2007 Alfred P. Sloan Research Fellowship in computational and molecular evolutionary biology and a 2008 Guggenheim Fellowship to further computational statistics. Recently, he received the 2011 Raymond J. Carroll Young Investigator Award for a leading statistician within 10 years post-Ph.D. Abstract: Following a series of high-profile drug safety disasters in recent years, many countries are redoubling their efforts to ensure the safety of licensed medical products. Large-scale observational databases such as claims databases or electronic health record systems are attracting particular attention in this regard, but present significant methodological and computational concerns. In this talk, I discuss how high-performance statistical computation, including graphics processing units, can enable complex inference methods in these massive datasets. I focus on algorithm restructuring through techniques like block relaxation (Gibbs, cyclic coordinate descent, MM) to exploit increased data/parameter conditional independence within traditional serial structures. I find orders-of-magnitude improvement in overall run-time fitting models involving tens of millions of observations. These approaches are ubiquitous in high-dimensional biological problems modeled through stochastic processes. To drive this point home, I conclude with a seemingly unrelated example developing nonparametric models to study the genomic evolution of infectious diseases. These infinite hidden Markov models (HMMs) generalize both Dirichlet process mixtures and the usual finite-state HMM to capture unknown heterogeneity in the evolutionary process. Data squashing strategies, coupled with massive parallelization, yield novel algorithms that bring these flexible models finally within our grasp.

Abstract: Heterogeneous and large volume of Electronic Health Records (EHR) data are becoming available in many healthcare institutes. Such EHR data from millions of patients serve as huge collective memory of doctors and patients over time. How to leverage that EHR data to help caregivers and patients to make better decisions in future? How to efficiently use these data to help clinical and pharmaceutical research? My research focuses on developing large-scale algorithms and systems for healthcare analytics. First, I will describe our healthcare analytic research framework, which provides an intuitive collaboration mechanism across interdisciplinary teams and an efficient computation framework for handling heterogeneous patient data. Second, I will present a core component of this framework, patient similarity learning that answers the following questions: - How to leverage physician feedback into the similarity computation? - How to integrate multiple patient similarity measures into a single consistent similarity measure? - How to incrementally update the existing patient similarity functions as new data or feedback arrive? - How to present the similarity results in an intuitive and interactive way to users? I will illustrate the effectiveness of our proposed algorithms for patient similarity learning in several different healthcare scenarios. I will demonstrate an interactive visual analytic system that allows users to cluster patients and to refine the underlying patient similarity metric. Finally, I will highlight some current/future work that I am pursuing.
