About Me

0:05 Nobody's born smart
1:08 Because the most beautiful, complex concepts in the whole universe are built on basic ideas
1:13 that anyone can learn, anywhere can understand. Whoever you are, whereever you are
1:18 You only have to know one thing: You can learn anything

What is Data Science?
da•ta
Factual information, especially information organized for
analysis or used to reason or make decisions.
Computer Science Numerical or other information
represented in a form suitable for processing by computer.
Values derived from scientific experiments.
sci·ence (sī′əns)
The observation, identification, description,
experimental investigation, and theoretical explanation
of phenomena. Ex. New advances in science and
technology.
Such activities restricted to a class of natural
phenomena. Ex. The science of astronomy.
A systematic method or body of knowledge in a given
area. Ex. The science of marketing.
Archaic Knowledge, especially that gained through
experience.

● Technological Advancements
● Cheaper Storage
● Faster Computations
● IOT
● RAD Tools

Growing Devices

Information Explosion & Doubling Processing Power
Metcalfe's law states that the value of a telecommunications network is
proportional to the square of the number of connected users of the system (n2).
Moore's law is the observation that the number of transistors in a dense integrated
circuit doubles approximately every two years.

How to do Data Science
You can use lots of sophisticated analytical & Business Intelligent tools and come to
a simple understandable explanations.
(or)
You can also use, simple tools like calculators or excel sheet to generate simple
and simple results.

Data Science - Tools
Too many to name, but none of them are close perfection.

Data Science Tools
● Languages: Scala, R, Python, Java, C#
● Lib: Scikit, DeepNet, Tensor flow, Theano, H20
● Frameworks: Apache Spark
These are some used by used us (Imaginea Labs - Data Sciences - 4th Floor, Hyd).

Suggestions
Challenges in DS & Tips to who want to start.

Suggestions?
● Data Preparation
○ “Give me six hours to chop down a tree and I will spend the first four sharpening the axe”.
Abraham Lincoln
○ Python, Scala, Excel, Databases(regex).
● Data Analytics
○ “Seeing is believing”
○ Python(Matplotlib, Seaborn), D3.Js, Excel.
● Data Models
○ “There are no perfect solutions, but some work better”
○ Learn 2-3 types of Clustering, Regression Models(LR,RF,SVM,KNN,XGB)
● Evaluation
○ “A product not tested is broken by default”
○ Accuracy, RMSE, Precision-Recall, F1 Score
