What is Data?
➢ Data is meaningless until its conversion into valuable information.
Definition :
“Data is different types of information usually formatted in a particular manner.”
What is Data Science?
“Data Science involves mining large datasets containing structured and unstructured data
and identifying hidden patterns to extract actionable insights.”
Introduction
1. The importance of Data Science lies in its innumerable uses that range from daily activities
like asking Alexa for recommendations, to more complex applications like operating a
self-driving car.
2. By 2025, global data will grow to 175 zettabytes. [Ref - www.niti.gov.in]
3. Data Science enables companies to efficiently understand gigantic data from multiple
sources and derive valuable insights to make smarter data-driven decisions.
4. Data Science is widely used in various industry domains, including marketing, healthcare,
finance, banking, policy work, and more. That explains why Data Science is important.

Applications of Data Science
A] Medical
Identifying Cancer Tumors
1. Google is now applying data science to healthcare. In fact, the company developed a tool, LYNA, for identifying
breast cancer tumors that metastasize to nearby lymph nodes. That can be difficult for the human eye to see, especially
when the new cancer growth is small. [https://ai.googleblog.com/2018/10/applying-deep-learning-to-metastatic.html]
2. In one trial, LYNA — short for Lymph Node Assistant —accurately identified metastatic cancer 99 percent of the time
using its machine-learning algorithm. More testing is required, however, before doctors can use it in hospitals.
Tracking Menstrual Cycles
1. The popular Clue app employs data science to forecast user’s menstrual cycles and reproductive health by tracking
cycle start dates, moods, stool type, hair condition and many other metrics.
2. Behind the scenes, data scientists mine this wealth of anonymized data with tools like Python and Jupyter’s Notebook.
Users are then algorithmically notified when they’re fertile, on the cusp of a period or at an elevated risk for conditions
like an ectopic pregnancy.
Applications of Data Science
A] Medical
PERSONALIZING TREATMENT PLANS
1. Oncora’s software uses machine learning to create personalized recommendations for current cancer patients based on data from
past ones.
2. Their radiology team collaborated with Oncora data scientists to mine 15 years’ worth of data on diagnoses, treatment plans,
outcomes and side effects from more than 50,000 cancer records. Based on this data, Oncora’s algorithm learned to suggest
personalized chemotherapy and radiation regimens.
CLEANING CLINICAL TRIAL DATA
1. Veeva is a cloud software company that provides data and software solutions for the healthcare industry.
2. The company’s reach extends through clinical, regulatory and commercial medical fields.
3. Veeva’s Vault EDC uses data science to clean clinical trial findings and help medical professionals make adjustments mid-
study.
Applications of Data Science
B] Transport
MODELING TRAFFIC PATTERNS
1. StreetLight uses data science to model traffic patterns for cars, bikes and pedestrians on North American streets. Based on a monthly influx
of trillions of data points from smartphones, in-vehicle navigation devices and more, Streetlight’s traffic maps stay up-to-date.
2. There are more granular than mainstream maps apps too: they can identify groups of commuters that use multiple transit modes to get to
work, like a train followed by a scooter. The company’s maps inform various city planning enterprises, including commuter transit design.
OPTIMIZING FOOD DELIVERY
1. The data scientists at Uber Eats have a fairly simple goal: getting hot food delivered quickly.
2. Making that happen across the country though, takes machine learning, advanced statistical modeling and staff meteorologists.
3. In order to optimize the full delivery process, the team has to predict how every possible variable — from storms to holiday rushes — will
impact traffic and cooking time.
Applications of Data Science
B] Transport
IMPROVING PACKAGE DELIVERY
1. UPS software uses data science to optimize package transport from drop-off to delivery.
2. The company’s integrated navigation system ORION helps drivers choose over 66,000 fuel-efficient routes.
3. ORION has saved UPS approximately 100 million miles and 10 million gallons of fuel per year with the use
of advanced algorithms, AI and machine learning.
4. The company plans to continue to update its ORION system, with the last version having been rolled out in
2021.
5. The latest update allowed drivers to reduce their routes by two to four miles.
Applications of Data Science
B] Sports Data Science Applications
MAKING PREDICTIVE INSIGHTS IN BASKETBALL
1. RSPCT’s shooting analysis system, adopted by NBA and college teams, relies on a sensor on a basketball
hoop’s rim (a metal ring holding the net), whose tiny camera tracks exactly when and where the ball strikes on
each basket attempt.
2. It funnels that data to a device that displays shot details in real time and generates predictive insights.
3. “Based on our data, we can tell [a shooter], ‘If you are about to take the last shot to win the game, don’t take
it from the top of the key, because your best location is actually the right corner,’
…………………………… RSPCT CEO Leo Moravtchik told to News team..
Applications of Data Science
B] Sports Data Science Applications
TRACKING PHYSICAL DATA FOR ATHLETES
1. WHOOP makes wearable devices that track athletes’ physical data like resting heart rate,
sleep cycle and respiratory rate.
2. The goal is to help athletes understand when to push their training and when to rest — and
to make sure they’re taking the necessary steps to get the most out of their body.
3. Professional athletes like Olympic sprinter Gabby Thomas, Olympic golfer Nelly Korda
and PGA golfer Nick Watney are among the WHOOPS’ users, according to the company’s
website.
