The first war Terminology
  • Analyzing data has a long history!
  • There have been many terms that have been used to
    describe such endeavors
  • Statistics
  • Artificial Intelligence
  • Machine learning
  • Data analytics
  • Since I happen to work in a Data Science
    program perhaps I may be allowed the indulgence
    of using that terminology

Whatever we call it, what makes things different
now?

The Good
Experiments, observations, and numerical
simulations in many areas of science and business
are currently generating terabytes of data, and
in some cases are on the verge of generating
petabytes and beyond. Analyses of the information
contained in these data sets have already led to
major breakthroughs in fields ranging from
genomics to astronomy and high-energy physics and
to the development of new information-based
industries.
The Bad
Given a large mass of data, we can by judicious
selection construct perfectly plausible
unassailable theoriesall of which, some of
which, or none of which may be right.

The Hopeful
The ability to take datato be able to understand
it, to process it, to extract value from it, to
visualize it, to communicate itthats going to
be a hugely important skill in the next decades,
not only at the professional level but even at
the educational level for elementary school kids,
for high school kids, for college kids. Because
now we really do have essentially free and
ubiquitous data. So the complimentary scarce
factor is the ability to understand that data and
extract value from it.

What is Big Data?
  • The are many examples of "data", but what makes
    some of it big? The classic definition
    revolves around the three Vs.
  • Volume, velocity, and variety.
  • Volume There is a just a lot of it being
    generated all the time. Things get interesting
    and big, when you cant fit it all on one
    computer anymore. Why? There are many ideas
    here such as MapReduce, Hadoop, etc. that all
    revolve around being able to process data that
    goes from Terabytes, to Petabytes, to Exabytes.
  • Velocity Data is being generated very quickly.
    Can you even store it all? If not, then what do
    you get rid of and what do you keep?
  • Variety The data types you mention all take
    different shapes. What does it mean to store
    them so that you can play with or compare them?

Is Big Data the same as Data Science?
  • Are Big Data and Data Science the same thing?
  • I wouldn't say so...
  • Data Science can be done on small data sets.
  • And not everything done using Big Data would
    necessarily be called Data Science.

Can you even be certain?
  • For real world problems, I claim that you will
    never be certain of any inferences from data.
  • I mean, what happens to your carefully thought
    out marketing plan for some rocking slacks when
    the Martians land.
  • What is unacceptable is when the data you
    actually have does not support the conclusion you
    report.
