DATA SCIENCE
(BIG DATA)
INTRODUCTION
•Today, we’re surrounded by data. People upload videos,
take pictures on their cell phones, text friends, update
their Facebook status, leave comments around the web,
click on ads, and so forth. Machines, too, are generating
and keeping more and more data.
•As the cost of computing power, data storage, and high
bandwidth Internet access and have plunged exponentially
over the past two decades data is the source for corporate
energy and differentiation in the 21st century.
ABSTRACT
Data Science refers to an emerging area of work concerned
with the collection, preparation, analysis, visualization,
management, and preservation of large collections of
information. Although the name Data Science to connect
most strongly with areas such as databases and computer
science, many different kinds of skills - including non
-mathematical skills are needed. Data science most often
refers to the tools and methods used to analyze large
amounts of data in many fields.
BIG DATA
What is Big Data…..???
Data science break big data into four
dimensions
1. Volume
2. Variety
3. Velocity
4. Veracity.
BIG DATA
Why Big Data….???
Facebook is collecting your data -
500 terabytes a day.
 Google currently processes over -
20 petabytes of data per day .
Day, week, month, year….???
So What do we Do….
Parallelization
•The obvious solution is that we use multiple processors t
o solve the same problem by fragmenting it into pieces.
•Imagine if we had 100 drives, each holding one hundred
th of the data. Working in parallel, we could read the data
in under two minutes.
Where is Big Data Used…..???
The Awesome Ways Big Data Is Used Today To Change Our World
•Understanding and Targeting Customers
•Improving Science and Research
• Improving Security and Law Enforcement.
• Improving and Optimizing Cities and Countries
•Financial Trading
•Improving Sports Performance
•Improving Healthcare and Public Health
•Personal Quantification and Performance Optimization
•Understanding and Optimizing Business Processes
DATA SCIENCE LOOP
Programming languages…
Big Data - Not a Big Deal for Conventional Programmers
Hadoop
Python
R language
SAS (Statistical Analysis System)
JULIA
Big Words About Big Data…
A McKinsey Global Institute report estimates that by 2018,
“the United States alone could face a shortage of 140,000 to
190,000 people with deep analytical skills as well as 1.5 million
managers and analysts with the know-how to use the analysis of
big data to make effective decisions.”
“Data Science is the Most Trending job for
the 21st century ”
“Data is the new science. Big data holds the answers.” – Pat Gel
singer, CEO, EMC, Big Bets on Big Data, Forbes
Future Scope
Data Science is necessary for companies to stay with the
pack and compete in the future.
Organizations are constantly making decisions based on gut
instinct, loudest voice and best argument – sometimes they are
even informed by real information. The winners and the losers in
the emerging data economy are going to be determined by their
Data Science teams.
Big data means big compensation for data scientists.
Data scientists are some of the most expensive and coveted professionals around
today. "It’s important to note that data mining as it relates to data science is not
traditionally taught in university-level computer science curricula," says Ray Bao
data scientist at CyberCoders.
Career
Tell Your Kids to be Data Scientists – Not Doctors
In the days of yore parents pushed their children
to pursue noble lucrative professions – doctor,
lawyer, banker – but as times change they may
soon encourage another career path: data scientist
.
Thank you
for
your attention
