  1. Liz Marai Pitt Computer Science CMU Robotics Institute (adj) LSST, 08/07/2008 Data Management and Visualization at Pitt CS

  2. Pitt Computer Science • Data Management • Graphics and Visualization • Artificial Intelligence • Core Systems • Theory and Algorithms • Small: 12 active faculty (avg. tier I: 25) • Strong: tier I (2 CAREER awards this summer only) • Excellent record of interdisciplinary collaboration

  3. Current Collaborations • Pitt School of Medicine • Orthopedics & Bioengineering • Center for Modeling Pulmonary Immunity • Center for Biomedical Informatics • Center for Computational Biology and Bioinformatics • Pitt Center for Modeling and Simulations (Chemistry) • CMU Robotics Institute • Center for Parallel, Distributed and Intelligent Systems • Pittsburgh Supercomputing Center

  4. Visualization Research Lab Department of Computer Science University of Pittsburgh

  5. Image Processing, Modeling & Simulation of Biological Structures w/ UPMC Orthopedics Medical measurements (images, motion, forces etc) Half of parameters not measurable, yet inferrable Uncertainty Multiple sources of data Predictive models and simulations

  6. Exploratory Visualization and Analysis Quantitative measures, incorporated into the modeling process (analysis) Anomaly detection (exploration)

  7. Annotations for Interdisciplinary Collaboration Miscalibration? Or valid observation?

  8. Software Tools for Visual Mining

  12. Data Flow Data Acquisition Web Data Management Data Stream Processing Data Dissemination

  13. Data Stream Management Systems • Alerting/Monitoring Service • Register query (filter) ahead of time • “Match” against incoming data stream • Generate “events” & notify users • Examples: • Stock market monitoring • Transient alerts • Google alerts • Detection of outbreak of diseases

  14. Efficient Query Scheduling (Results) 73% Avg. Response Time (Sec) 65%

  15. User-centric Web-data Management 4:26 AM ET • Given an option, would you prefer slightly-stale results fast OR fresh results, slightly delayed?

  16. How to capture user preferences? • Proposed Quality Contracts Framework • Micro-economic paradigm • Combination of quality functions • Consider Quality of Service (response time) • Consider Quality of Data (freshness) • Basic idea: • Convert performance on individual metric into “worth” to users • Use Quality Contracts to guide resource allocation

  17. Center for Modeling Pulmonary Immunity + =

  18. Scientific Data Management • Biological Data Management • Center for Modeling Pulmonary Immunity • NIH-funded (2005 - 2009) • 4 centers in the US • Build mathematical models of immune response • http://cmpi.cs.pitt.edu • Data exchange server • Platform to record all experimental information • Enable sharing & interoperability across centers

  19. Data Exchange Server • Platform to exchange experimental data • Goal 1: organize data already online • Goal 2: capture data from notebooks • Goal 3: allow for new data to be recorded • Provenance (data lineage) • Annotations • Goal 4: export / import capability • Goal 5: make repository user-friendly • Goal 6: minimize need for data cleaning • Goal 7: make repository active (alerts) • Publish / Subscribe
