why this meetup
Why this meetup?
  • We have excellent meetup groups in Atlanta for various data tools:
    • Hadoop
    • R
    • LexisNexis-HPCC
  • Tools are only a part of Data Science
  • We need a place for discussing broader Data Science techniques and other topics
  • Which brings us to the question…
what is data science
What is Data Science?

Term coined jointly by Jeff Hammerbacher and DJ Patil

  • Machine Learning
  • Data Mining
  • Statistical Modeling
  • Exploratory Statistics
  • BIG DATA
  • Coding/Scripting/Hacking
  • Data visualization
  • Infographics/mashups
  • Business Intelligence
  • Qualitative skills

Drew Conway’s famous Venn Diagram
