Introduction to AI: Basics of AI 
As discussed in the last chapter, Artificial Intelligence has always been a term which intrigues people 
all over the world. Various organisations have coined their own versions of defining Artificial 
Intelligence. Some of them are mentioned below: 
  NITI Aayog: National Strategy for Artificial Intelligence 
AI refers to the ability of machines to perform cognitive tasks like thinking, perceiving, learning, 
problem solving and decision making. Initially conceived as a technology that could mimic human 
intelligence, AI has evolved in ways that far exceed its original conception. With incredible advances 
made in data collection, processing and computation power, intelligent systems can now be deployed 
to take over a variety of tasks, enable connectivity and enhance productivity. 
  World Economic Forum 
Artificial intelligence (AI) is the software engine that drives the Fourth Industrial Revolution. Its impact 
can already be seen in homes, businesses and political processes. In its embodied form of robots, it 
will soon be driving cars, stocking warehouses and caring for the young and elderly. It holds the 
promise of solving some of the most pressing issues facing society, but also presents challenges such 
as inscrutable “black box” algorithms, unethical use of data and potential job displacement. As rapid 
advances in machine learning (ML) increase the scope and scale of AI’s deployment across all aspects 
of daily life, and as the technology itself can learn and change on its own, multi-stakeholder 
collaboration is required to optimize accountability, transparency, privacy and impartiality to create 
trust. 
  European Artificial Intelligence (AI) leadership, the path for an integrated vision 
AI is not a well-defined technology and no universally agreed definition exists. It is rather a cover term 
for techniques associated with data analysis and pattern recognition. AI is not a new technology, 
having existed since the 1950s. While some markets, sectors and individual businesses are more 
advanced than others, AI is still at a relatively early stage of development, so that the range of 
potential applications, and the quality of most existing applications, have ample margins left for 
further development and improvement. 
 
Artificial intelligence (AI), is the ability of a digital computer or computer-controlled robot to 
perform tasks commonly associated with intelligent beings. The term is frequently applied to the 
project of developing systems endowed with the intellectual processes characteristic of humans, such 
as the ability to reason, discover meaning, generalize, or learn from past experience.

AI theory and development of computer systems (both machines and software) enables machines to 
perform tasks that normally require human intelligence.

field in the future. Overall, its core idea is building machines and algorithms which are capable of

AI, ML & DL 
As you have been progressing towards building AI readiness, you must have come across a very 
common dilemma between Artificial Intelligence (AI) and Machine Learning (ML). Many times, these 
terms are used interchangeably but are they the same? Is there no difference in Machine Learning 
and Artificial Intelligence? Is Deep Learning (DL) Also Artificial Intelligence? What exactly is Deep

Artificial Intelligence (AI) 
Refers to any technique that enables computers to mimic human intelligence.  It gives the ability to 
machines to recognize a human’s face; to move and manipulate objects; to understand the voice 
commands by humans, and also do other tasks. The AI-enabled machines think algorithmically and 
execute what they have been asked for intelligently. 
Machine Learning (ML) 
It is a subset of Artificial Intelligence which enables machines to improve at tasks with experience 
(data). The intention of Machine Learning is to enable machines to learn by themselves using the 
provided data and make accurate Predictions/ Decisions.

* Images shown here are the property of individual organisations and are used here for reference purpose only. 
 
Deep Learning (DL) 
It enables software to train itself to perform tasks with vast amounts of data. In Deep Learning, the 
machine is trained with huge amounts of data which helps it in training itself around the data. Such 
machines are intelligent enough to develop algorithms for themselves. Deep Learning is the most 
advanced form of Artificial Intelligence out of these three. Then comes Machine Learning which is 
intermediately intelligent and Artificial Intelligence covers all the concepts and algorithms which, in 
some way or the other mimic human intelligence. 
There are a lot of applications of AI out of which few are those which come under ML out of which 
very few can be labelled as DL. Therefore, Machine Learning (ML) and Deep Learning (DL) are part of 
Artificial Intelligence (AI), but not everything that is Machine learning will be Deep learning. 
Introduction to AI Domains 
Artificial Intelligence becomes intelligent according to the training which it gets. For training, the 
machine is fed with datasets. According to the applications for which the AI algorithm is being 
developed, the data which is fed into it changes. With respect to the type of data fed in the AI 
model, AI models can be broadly categorised into three domains: 
Data Sciences 
Data sciences is a domain of AI related to data systems and processes, in which the system collects 
numerous data, maintains data sets and derives meaning/sense out of them.  
The information extracted through data science can be used to make a decision about it.  
Example of Data Science 
Price Comparison Websites  
These websites are being driven by lots and lots of data. If you have 
ever used these websites, you would know, the convenience of 
comparing the price of a product from multiple vendors at one 
place. PriceGrabber, PriceRunner, Junglee, Shopzilla, DealTime are 
some examples of price comparison websites. Now a days, price 
comparison website can be found in almost every domain such as 
technology, hospitality, automobiles, durables, apparels etc. 
 
 
Computer Vision 
Computer Vision, abbreviated as CV, is a domain of AI that depicts the capability of a machine to get 
and analyse visual information and afterwards predict some decisions about it. The entire process 
involves image acquiring, screening, analysing, identifying and extracting information. This extensive 
processing helps computers to understand any visual content and act on it accordingly. In computer 
vision, Input to machines can be photographs, videos and pictures from thermal or infrared sensors, 
indicators and different sources.

Computer vision related projects translate digital visual data into descriptions. This data is then turned 
into computer-readable language to aid the decision-making process. The main objective of this 
domain of AI is to teach machines to collect information from pixels.  
Examples of Computer Vision 
Self-Driving cars/ Automatic Cars 
CV systems scan live objects and analyse them, based on whether 
the car decides to keep running or to stop. 
 
 
 
 
Face Lock in Smartphones 
Smartphones nowadays come with the feature of face locks in 
which the smartphone’s owner can set up his/her face as an 
unlocking mechanism for it. The front camera detects and captures 
the face and saves its features during initiation. Next time onwards, 
whenever the features match, the phone is unlocked. 
 
 
Natural Language Processing 
Natural Language Processing, abbreviated as NLP, is a branch of artificial intelligence that deals with 
the interaction between computers and humans using the natural language. Natural language refers 
to language that is spoken and written by people, and natural language processing (NLP) attempts to 
extract information from the spoken and written word using algorithms.  
The ultimate objective of NLP is to read, decipher, understand, and make sense of the human languages 
in a manilr that is valuable. 
Examples of Natural Language Processing 
 
Email filters 
Email filters are one of the most basic and 
initial applications of NLP online. It started 
out with spam filters, uncovering certain 
words or phrases that signal a spam 
message.
