- 4. Notre Dame CCL Meeting October 11 20139/29/13 Requirements and Use Case Subgroup 4 The focus is to form a community of interest from industry, academia, and government, with the goal of developing a consensus list of Big Data requirements across all stakeholders. This includes gathering and understanding various use cases from diversified application domains. Tasks • Gather use case input from all stakeholders • Derive Big Data requirements from each use case. • Analyze/prioritize a list of challenging general requirements that may delay or prevent adoption of Big Data deployment • Work with Reference Architecture to validate requirements and reference architecture • Develop a set of general patterns capturing the “essence” of use cases (to do)
- 5. Notre Dame CCL Meeting October 11 20139/29/13 Use Case Template • 26 fields completed for 51 areas • Government Operation: 4 • Commercial: 8 • Defense: 3 • Healthcare and Life Sciences: 10 • Deep Learning and Social Media: 6 • The Ecosystem for Research: 4 • Astronomy and Physics: 5 • Earth, Environmental and Polar Science: 10 • Energy: 1
- 6. Notre Dame CCL Meeting October 11 20139/29/13 51 Detailed Use Cases: Many TB’s to Many PB’s • Government Operation: National Archives and Records Administration, Census Bureau • Commercial: Finance in Cloud, Cloud Backup, Mendeley (Citations), Netflix, Web Search, Digital Materials, Cargo shipping (as in UPS) • Defense: Sensors, Image surveillance, Situation Assessment • Healthcare and Life Sciences: Medical records, Graph and Probabilistic analysis, Pathology, Bioimaging, Genomics, Epidemiology, People Activity models, Biodiversity • Deep Learning and Social Media: Driving Car, Geolocate images/cameras, Twitter, Crowd Sourcing, Network Science, NIST benchmark datasets • The Ecosystem for Research: Metadata, Collaboration, Language Translation, Light source experiments • Astronomy and Physics: Sky Surveys compared to simulation, Large Hadron Collider at CERN, Belle Accelerator II in Japan • Earth, Environmental and Polar Science: Radar Scattering in Atmosphere, Earthquake, Ocean, Earth Observation, Ice sheet Radar scattering, Earth radar mapping, Climate simulation datasets, Atmospheric turbulence identification, Subsurface Biogeochemistry (microbes to watersheds), AmeriFlux and FLUXNET gas sensors • Energy: Smart grid • Next step involves matching extracted requirements and reference architecture • Alternatively develop a set of general patterns capturing the “essence” of use cases
- 7. Notre Dame CCL Meeting October 11 20139/29/13 Some Trends • Also from IEEE Big Data conference in Santa Clara • Practitioners consider themselves Data Scientists • Images are a major source of Big Data – Radar – Light Synchrotrons – Phones – Bioimaging 7 • Hadoop and HDFS dominant • Business – main emphasis at NIST – interested in analytics and assume HDFS • Academia also extremely interested in data management • Clouds v. Grids
- 8. Notre Dame CCL Meeting October 11 20139/29/13 Example Use Case I: Summary of Genomics • Application: NIST/Genome in a Bottle Consortium integrates data from multiple sequencing technologies and methods to develop highly confident characterization of whole human genomes as reference materials, and develop methods to use these Reference Materials to assess performance of any genome sequencing run. • Current Approach: The storage of ~40TB NFS at NIST is full; there are also PBs of genomics data at NIH/NCBI. Use Open-source sequencing bioinformatics software from academic groups (UNIX-based) on a 72 core cluster at NIST supplemented by larger systems at collaborators. • Futures: DNA sequencers can generate ~300GB compressed data/day which volume has increased much faster than Moore’s Law. Future data could include other ‘omics’ measurements, which will be even larger than DNA sequencing. Clouds have been explored. 8
- 9. Notre Dame CCL Meeting October 11 20139/29/13 Example Use Case II: Census Bureau Statistical Survey Response Improvement (Adaptive Design) • Application: Survey costs are increasing as survey response declines. The goal of this work is to use advanced “recommendation system techniques” that are open and scientifically objective, using data mashed up from several sources and historical survey para-data (administrative data about the survey) to drive operational processes in an effort to increase quality and reduce the cost of field surveys. • Current Approach: About a petabyte of data coming from surveys and other government administrative sources. Data can be streamed with approximately 150 million records transmitted as field data streamed continuously, during the decennial census. All data must be both confidential and secure. All processes must be auditable for security and confidentiality as required by various legal statutes. Data quality should be high and statistically checked for accuracy and reliability throughout the collection process. Use Hadoop, Spark, Hive, R, SAS, Mahout, Allegrograph, MySQL, Oracle, Storm, BigMemory, Cassandra, Pig software. • Futures: Analytics needs to be developed which give statistical estimations that provide more detail, on a more near real time basis for less cost. The reliability of estimated statistics from such “mashed up” sources still must be evaluated. 9
- 10. Notre Dame CCL Meeting October 11 20139/29/13 Example Use Case III: Large-scale Deep Learning • Application: Large models (e.g., neural networks with more neurons and connections) combined with large datasets are increasingly the top performers in benchmark tasks for vision, speech, and Natural Language Processing. One needs to train a deep neural network from a large (>>1TB) corpus of data (typically imagery, video, audio, or text). Such training procedures often require customization of the neural network architecture, learning criteria, and dataset pre-processing. In addition to the computational expense demanded by the learning algorithms, the need for rapid prototyping and ease of development is extremely high. • Current Approach: The largest applications so far are to image recognition and scientific studies of unsupervised learning with 10 million images and up to 11 billion parameters on a 64 GPU HPC Infiniband cluster. Both supervised (using existing classified images) and unsupervised applications investigated. • Futures: Large datasets of 100TB or more may be necessary in order to exploit the representational power of the larger models. Training a self-driving car could take 100 million images at megapixel resolution. Deep Learning shares many characteristics with the broader field of machine learning. The paramount requirements are high computational throughput for mostly dense linear algebra operations, and extremely high productivity for researcher exploration. One needs integration of high performance libraries with high level (python) prototyping environments. 10
- 11. Notre Dame CCL Meeting October 11 20139/29/13 Example Use Case IV: EISCAT 3D incoherent scatter radar system • Application: EISCAT, the European Incoherent Scatter Scientific Association, conducts research on the lower, middle and upper atmosphere and ionosphere using the incoherent scatter radar technique. This technique is the most powerful ground-based tool for these research applications. EISCAT studies instabilities in the ionosphere, as well as investigating the structure and dynamics of the middle atmosphere. It is also a diagnostic instrument in ionospheric modification experiments with addition of a separate Heating facility. Currently EISCAT operates 3 of the 10 major incoherent radar scattering instruments worldwide with its facilities in in the Scandinavian sector, north of the Arctic Circle. • Current Approach: The current running old EISCAT radar generates terabytes per year rates and does not present special challenges. • Futures: The design of the next generation radar, EISCAT_3D, will consist of a core site with a transmitting and receiving radar arrays and four sites with receiving antenna arrays at some 100 km from the core. The fully operational 5-site system will generate several thousand times data of current EISCAT system with 40 PB/year in 2022 and is expected to operate for 30 years. EISCAT 3D data e- Infrastructure plans to use the high performance computers for central site data processing and high throughput computers for mirror sites data processing. Downloading the full data is not time critical, but operations require real-time information about certain pre-defined events to be sent from the sites to the operation center and a real-time link from the operation center to the sites to set the mode of radar operation on with immediate action. 11
- 12. Notre Dame CCL Meeting October 11 20139/29/13 Example Use Case V: Consumption forecasting in Smart Grids • Application: Predict energy consumption for customers, transformers, sub-stations and the electrical grid service area using smart meters providing measurements every 15-mins at the granularity of individual consumers within the service area of smart power utilities. Combine Head-end of smart meters (distributed), Utility databases (Customer Information, Network topology; centralized), US Census data (distributed), NOAA weather data (distributed), Micro-grid building information system (centralized), Micro-grid sensor network (distributed). This generalizes to real-time data-driven analytics for time series from cyber physical systems • Current Approach: GIS based visualization. Data is around 4 TB a year for a city with 1.4M sensors in Los Angeles. Uses R/Matlab, Weka, Hadoop software. Significant privacy issues requiring anonymization by aggregation. Combine real time and historic data with machine learning for predicting consumption. • Futures: Wide spread deployment of Smart Grids with new analytics integrating diverse data and supporting curtailment requests. Mobile applications for client interactions. 12

- 14. Notre Dame CCL Meeting October 11 20139/29/13 Definitions and Taxonomies Subgroup 14 • The focus is to gain a better understanding of the principles of Big Data. It is important to develop a consensus-based common language and vocabulary terms used in Big Data across stakeholders from industry, academia, and government. In addition, it is also critical to identify essential actors with roles and responsibility, and subdivide them into components and sub-components on how they interact/ relate with each other according to their similarities and differences. Tasks • For Definitions: Compile terms used from all stakeholders regarding the meaning of Big Data from various standard bodies, domain applications, and diversified operational environments. • For Taxonomies: Identify key actors with their roles and responsibilities from all stakeholders, categorize them into components and subcomponents based on their similarities and differences
- 15. Notre Dame CCL Meeting October 11 20139/29/13 Data Science Definition (Big Data less consensus) • Data Science is the extraction of actionable knowledge directly from data through a process of discovery, hypothesis, and analytical hypothesis analysis. • A Data Scientist is a practitioner who has sufficient knowledge of the overlapping regimes of expertise in business needs, domain knowledge, analytical skills and programming expertise to manage the end-to-end scientific method process through each stage in the big data lifecycle. 15 Big Data refers to digital data volume, velocity and/or variety whose management requires scalability across coupled horizontal resources
