Big Data: think-tank Policy Exchange
Big Data: datasets that are too
awkward to work with using traditional,
hands-on database management tools.
Big Data Analytics: the process of
examining and interrogating big data
assets to derive insights of value for
decision making.

What is Big Data?
Big Data is a term that describes
large volumes of high velocity,
complex and variable data that
require advanced techniques and
technologies to enable the capture,
storage, distribution, management,
and analysis of the information.

The three Vs of Big Data
Source: D. Soubra (2012), The 3Vs that define Big Data.

The other “Vs” in Big Data
“ ’Vs’ like veracity,
validity, value,
viability, etc. are
aspirational qualities
of all data, not
definitional qualities of
Big Data.”
 Doug Laney

What is really important in Big Data?
“The Big in Big Data relates to
importance not size”
 Rafael Irizarry

My best “V”

Is Big Data a marketing campaign?
“If you’re like me, the mere mention of Big Data now
turns your stomach.
Nearly every business intelligence (BI) vendor,
publication, and event has Big Data flashing in neon
colors in Times Square dimensions.
Never before have I seen an idea in the BI space elicit
this much obsession. Why all the fuss? Why, indeed.
Essentially, Big Data is a marketing campaign, pure
and simple.”
 Stephen Few

Big Data: McKinsey Report
 140.000 – 190.000 more deep analytical talent positions,
and 1.5 million data savvy managers needed to take full
advantage of Big Data in the USA.
 Techniques: data mining (cluster analysis, classification,
regression, etc), (un)supervised learning, ML, neural
networks, optimization, predictive modeling, statistics,
simulation, etc.
 Technologies: BI, Cassandra, DW, ETL, Hadoop, HBase,
Map/Reduce, R, RDBMS, etc.
 Potential of Big Data in five domains:
 Healthcare
 Public Sector
 Retail
 Manufacturing
 Telecommunications.

Market & jobs opportunity
 The demand for Big Data services spending
projected to reach $132,300M in 2015.
 By 2015, Big Data demand will reach 4.4 million
jobs globally, but only one-third of those jobs will
be filled.
 The demand for services will generate 550,000
external services jobs in the next 3 years.
 Another 40,000 jobs will be created at software
vendors in the next 3 years.

Statiscian: a sexy job
“I keep saying the sexy job in the next ten years will be
statisticians.
People think I’m joking, but who would’ve guessed that
computer engineers would’ve been the sexy job of the
1990s?
The ability to take data—to be able to understand it, to
process it, to extract value from it, to visualize it, to
communicate it—that’s going to be a hugely
important skill in the next decades [...]”

Data Scientist skill set: ACM
A data scientist requires an integrated
skill set spanning mathematics,
machine learning, artificial
intelligence, statistics, databases, and
optimization, along with a deep
understanding of the craft of problem
formulation to engineer effective
solutions.

Data→Info→Knowledge→Understanding
→Wisdom!!
“There are known knowns.
These are things we know that
we know.
There are known unknowns.
That is to say, there are things
that we know we don't know.
But there are also unknown
unknowns. There are things we
don't know we don't know.”

Data Science Teams
Data scientists as having the following qualities:
 Technical expertise: the best data scientists typically have
deep expertise in some scientific discipline.
 Curiosity: a desire to go beneath the surface and discover
and distill a problem down into a very clear set of
hypotheses that can be tested.
 Storytelling: the ability to use data to tell a story and to be
able to communicate it effectively.
 Cleverness: the ability to look at a problem in different,
creative ways.
