Data Science
 "Data Science" was used by
statisticians and economist in early
1970 and defined by Peter Naur in
1974.
 Data Science” has gained popularity in
the last couple of years because of the
massive data deposits
 Usage of Big Data technology to
explore data used in large corporates,
government and industries made the
term data science catchy.

Data Science as Discipline
 Data Science has emerged as a new discipline to
provide deep insight on the large volume of data.
 Data Science is fusion of major disciplines like
Computational Algorithms, Statistics and
Visualization
 90% of the world’s data has been created in the
last two years which includes 10% of structured
data and 80% of unstructured data
 The digital universe is in data deluge and
estimated to be larger than the physical universe
and data unit measurement is predicted as
Geopbytes

Data Analytics – Need for
today
 Data considered as digital asset
similar to other property.
 The organizations believe data
generated by them will provide deep
insights to understand their business
process for arriving strategic
decisions.
 The earlier limitation of computational
storage and processing is overcome
by the technologies of cloud
computing and big data techniques.

Data Science Vs Data Analytics
 Data Science is a discipline which
groups techniques and methods from
various domains to study about data
and data analytics is a component in
Data Science.
 Data Analytics is a process of
analyzing the dataset to find deep
insights of data using computational
algorithms and statistical methods.

Analytics – Success Scenario

ORION - Franz Edelman
Award,
 Award which recognizes excellence in Operations Research and analytics
 ORION, an acronym that stands for On-Road Integrated Optimization and
Navigation, is perhaps the largest commercial analytics project ever
undertaken.
 It’s required well over a decade to build and roll out, and more than $250
million of investment by UPS.
 At its peak, over 700 UPSers were working on change management and
rollout of the system. So the company clearly went all in on this project.
 The company is receiving something in return for its investment; and indeed
it is.
 savings (in driver productivity and fuel economy) of between $300 and $400
million a year?
 How about 100 million fewer miles driven and a resulting cut in carbon
emissions of 100,000 metric tons a year?
 benefit from an analytics project very often, and these have been confirmed
through intensive measurement and reported to Wall Street analysts. –

Predictive analytics - Netflix
 Netflix, however, has raised the TV
show batting average considerably.
 The company’s use of predictive
analytics to improve customer
recommendation algorithms for
movies.
 The company has used analytics to
predict whether TV shows will be
home runs, solid base hits, or

Predictive Analytics – 2022
Source - Dataquest
 Antitheft. As you enter your car, a predictive model establishes your identity
based on several biometric readings, rendering it virtually impossible for an
imposter to start the engine.
 Entertainment. Spotify plays new music it predicts you will like.
 Traffic. Your navigator pipes up and suggests alternative routing due to
predicted traffic delays. Because the new route has hills and your car’s
battery – its only energy source – is low, your maximum acceleration is
decreased.
 Breakfast. An en route drive-through restaurant is suggested by a
recommendation system that knows its daily food preference predictions
must be accurate or you will disable it.
 Social. Your Social Techretary offers to read you select Facebook feeds and
Match.com responses it predicts will be of greatest interest. Inappropriate
comments are filtered out. CareerBuilder offers to read postings of jobs for
which you’re predicted to apply. When playing your voice mail, solicitations
such as robocall messages are screened by a predictive model just like e-
mail spam.
 Deals. You accept your smartphone’s offer to read to you a text message
from your wireless carrier. Apparently, they’ve predicted you’re going to
switch to a competitor, because they are offering a huge discount on theDr.V.Bhuvaneswari, Asst.Professor, Dept. of Computer Applications, Bhararthiar University 34

IoT- Data Analytics -
Manufacturing
 According to Accenture, the Industrial
Internet of Things has the potential to
add more than $14 trillion to the global
economy by 2030.
 Small sensors placed on complex
machinery emit performance data that
can be used to adjust scheduled
maintenance.
 With this functionality, industries such as
energy and oil extraction are now able to
predict and mitigate equipment failures,
significantly reducing downtime,
increasing site safety, and cutting costs.
Dr.V.Bhuvaneswari, Asst.Professor, Dept. of Computer Applications, Bhararthiar University 35

IoT – Big Data Analytics
 Experts are predicting fully automated farms in the next five years,
but already monster machines, such as the New Holland T8.435
tractor, are becoming commonplace not only on very big farms, but
also on mid-sized ones.
 The tractor’s steering is assisted by satellite. It downloads crop and
soil data straight to agronomists and farm managers, works 24/7,
can link with ground sensors and drones using infrared thermal
cameras to tell, within a square meter, the size of a field and where
the most fertile or waterlogged places are. Big data, machinery,
climatology, and agronomy are all combining to increase productivity
and reduce labor costs.
 Livestock farming has not gone unnoticed by big data and IoT
developers, either. Wearable technology is no longer just for
humans. Any animal, from elephants to cows to cats and dogs, can
wear or be injected with devices that capture health and behavioral
data.
 iNOVOTEC Animal Care, for example, has created wearable and
ingestible devices that provide information about an animal’s
condition that is not easily observable. This enables farmers to catch
illnesses much earlier, leading to healthier stock and cost savings.
