   报告题目：Big Data: A U. S. Perspective
    In 2014, it is projected that about 5 zettabytes (or 10**21 bits) of digital data are being generated per year by everything from underground physics experiments to retail transactions to global positioning systems to the Internet of Things. In the U. S., programs are being funded to deal with Big Data in all five sectors (i.e., services, manufacturing, construction, agriculture and mining) of the economy. While the focus of this paper is on Big Data from a U. S. perspective, it should be emphasized that data - especially big data - is worthless for decision making unless it is analyzed or processed to yield critical information which can then be employed to make informed decisions. Big Data is poised to add greater value to businesses; to understand planet earth; to solve science and engineering problems; to enhance the World Wide Web; and to aid national security agencies. It should be noted that Big Data is not a panacea for all analytical problems; nevertheless, it can support informed - yet, not necessarily defensible or knowledgeable - decisions or choices. More specifically, it can somewhat overcome data quality issues with data quantity, data access restrictions with on-demand cloud computing, causative analysis with correlative data analytics, and model-driven with evidence-driven applications.

    In 2007, Dr. James M. Tien became a Distinguished Professor and the Dean of the College of Engineering at the University of Miami, Coral Gables, Florida. He received the BEE from Rensselaer Polytechnic Institute (RPI) and the SM, EE and PhD from the Massachusetts Institute of Technology (MIT). He has held leadership positions at Bell Telephone Laboratories, at the Rand Corporation, and at Structured Decisions Corporation (which he co-founded). He joined the Department of Electrical, Computer and Systems Engineering at RPI in 1977, became Acting Chair of the department, joined a unique interdisciplinary Department of Decision Sciences and Engineering Systems as its founding Chair, and twice served as the Acting Dean of Engineering. Dr. Tien has published extensively, been invited to present dozens of plenary lectures, and been honored with both teaching and research awards, including being elected a Fellow in IEEE, INFORMS and AAAS and being a recipient of the IEEE Joseph G. Wohl Outstanding Career Award, the IEEE Major Educational Innovation Award, the IEEE Norbert Wiener Award, the IEEE Richard M. Emberson Award, and the IBM Faculty Award. He received a Doctor of Engineering (honoris causa ) from Canada's University of Waterloo and is also an Honorary Professor at over a dozen non-U.S. universities. Dr. Tien is an elected member of the prestigious U. S. National Academy of Engineering.
