Artificial Intelligence
 Composed of two words Artificial and Intelligence.
 Artificial – "man-made," and intelligence – "thinking power", hence
Artificial Intelligence means "a man-made thinking power.“
 The term AI was introduced by Prof. John McCarthy in the
conference at Dartmouth College in 1956.
 McCarthy defines AI as the “science and engineering of making
intelligent machines, especially intelligent computer programs”.

 Machine Learning is an advanced form
of AI where the machine can learn as it
goes rather than having every action
programmed by humans.
 Neural networks are biologically
inspired networks that extract features
from the data in a hierarchical fashion.
 The field of neural networks with
several hidden layers is called deep
learning.

appliances to aircraft autopilots.
Stage 2- Context Awareness and Retention
 Algorithms that develop information about the specific domain they are
being applied in.
 Well known applications of this level are chatbots and “robo-advisors”.

Levels of AI
Stage 3- Domain specific Expertise
 These systems build up expertise in a specific context taking in
massive volumes of information
Stage 4- Reasoning Machines
 These algorithms have some ability to attribute mental states to
themselves

1. Weak AI/ Artificial Narrow Intelligence (ANI)
 AI systems that perform specific tasks accurately and correctly.
 The strength of ANI is that it focuses on doing something extremely
well, sometimes exceeding a human’s capabilities.
 ANI is a good fit for automating simple and repetitive tasks.
Types of AI - Based on their Capabilities

3. Super/ Artificial Super Intelligence (ASI)
 ASI refers to machines that surpass humans in general intelligence.
 Nick Bostrom, defines ASI as “an intellect that is much smarter than
the best human brains in practically every field, including scientific
creativity, general wisdom and social skills.”
 The unique capabilities of the human brain are the reason why humans
have a dominant position over other species.

1. Reactive Machines
 The most basic types of AI.
 Do not store memories or past experiences for future actions.
 Only focus on current scenarios and react on it
Types of AI - Based on their Functionality

24
2. Limited Memory
 Can store past experiences or some data for a short period of time.
 These machines can use stored data for a limited time period only.
 Self-driving cars are one of the best examples of Limited Memory
systems. These cars can store the recent speed of nearby cars, the
distance of other cars, speed limits, and other information to navigate
the road.
Cont.…

25
3. Theory of Mind
 AI should understand human emotions, people beliefs, and be able to
interact socially like humans.
 This type of AI machine is still not developed, but researchers are
making lots of efforts and improvements for developing such AI
machines.
4. Self Awareness
 Self-awareness AI is the future of Artificial Intelligence. These
machines will be super intelligent and will have their own
consciousness, sentiments, and self awareness.

26
How does a Human Think?
 Intelligence or the cognitive process is composed of three main stages:
• Observe and input the information or data in the brain.
• Interpret and evaluate the input that is received from the
surrounding environment.
• Make decisions as a reaction towards what you received as an input
and interpreted and evaluated.

27
Mapping Human Thinking to AI Components
 Because AI is the science of simulating human thinking, it is possible to
map the human thinking stages to the layers or components of AI
systems.

28
 Acquire information from
their surrounding
environments through
human senses.
• Hearing and
• Sight senses
1st
stage
Humans AI
 Represented by the sensing
layer, which perceives
information from the
surrounding environment.
• voice recognition for sensing
voice
• visual imaging recognition for
sensing images

29
 Interpreting and evaluating
the input data
 Human brain
2nd
stage
Humans AI

the gathered input that is
acquired by the sensing layer.

30
 Taking action or making
decisions

Sample AI Applications
 Facebook - When you upload photos to Facebook, the service
automatically highlights faces and suggests friends to tag.
 Pinterest - Pinterest uses computer vision, an application of AI where
computers are taught to “see,” in order to automatically identify objects
in images (or “pins”) and then recommend visually similar pins
 Instagram – Instagram uses machine learning to identify the contextual
meaning of emoji, which have been steadily replacing slang (for
instance, a laughing emoji could replace “lol”)
 Snapchat - Snapchat introduced facial filters, called Lenses, in 2015.
These filters track facial movements, allowing users to add animated
effects or digital masks that adjust when their faces moved.
