What is AI?
Views of AI fall into four categories:
Thinking humanlyThinking
rationally
Acting humanlyActing rationally
The textbook advocates "acting rationally“
List of AI-topics

Prof. Venkatesh, CSE, UVCE, Bengaluru
7

Thinking Humanly
Through introspection
Through psychological experiments
Through brain imaging
Build systems that mimic the way humans think
and solve problems
Thinking Rationally
Laws of thought were supposed to govern the
operation of the mind; their study initiated the
field called logic.
Modelling thinking as a logical process.
10/29/25Prof. Venkatesh, CSE, UVCE, Bengaluru
8

Acting Humanly
Creating a system that can exhibit
behavior indistinguishable from that of
a human
Turing Test: NLP, Knowledge,
representation, Automated reasoning,
Machine Learning
Act Rationally
A rational agent is one that acts so as
to achieve the best outcome
10/29/25Prof. Venkatesh, CSE, UVCE, Bengaluru
9

Thinking Humanly
“The exciting new effort to make computers
think ...machines with minds, in the full and
literal sense.” (Haugeland, 1985)
“[The automation of] activities that we associate
with human thinking, activities such as
decision-making, problem solving, learning ...”
(Bellman, 1978)
10/29/25Prof. Venkatesh, CSE, UVCE, Bengaluru
10

Thinking Rationally
“The study of mental faculties through
the use of computational models.”
(Charniak and McDermott, 1985)
 “The study of the computations that
make it possible to perceive, reason,
and act.” (Winston, 1992)
10/29/25Prof. Venkatesh, CSE, UVCE, Bengaluru
11

Acting Humanly
“The art of creating machines that perform
functions that require intelligence when
performed by people.” (Kurzweil, 1990)
“The study of how to make computers do
things at which, at the moment, people are
better.” (Rich and Knight, 1991)
10/29/25Prof. Venkatesh, CSE, UVCE, Bengaluru
12

Acting Rationally
“Computational Intelligence is the
study of the design of intelligent
agents.” (Poole et al., 1998)
“AI ...is concerned with intelligent be
havior in artifacts.” (Nilsson, 1998)

What is Artificial Intelligence
(John McCarthy , Basic Questions)
What is artificial intelligence?
It is the science and engineering of making intelligent machines, especially
intelligent computer programs. It is related to the similar task of using
computers to understand human intelligence, but AI does not have to confine
itself to methods that are biologically observable.
Yes, but what is intelligence?
Intelligence is the computational part of the ability to achieve goals in the
world. Varying kinds and degrees of intelligence occur in people, many
animals and some machines.
Isn't there a solid definition of intelligence that doesn't depend on
relating it to human intelligence?
Not yet. The problem is that we cannot yet characterize in general what kinds
of computational procedures we want to call intelligent. We understand some
of the mechanisms of intelligence and not others.

What is Artificial
Intelligence?
Alfred Binet (1905): “Intelligence is the ability to judge
well, to understand well, and to reason well”.
AI: Technical and Scientific field devoted to design
“Engineered system” that generate output such as
content, perform prediction, recommendations or
helps in decision-making for given human-specified
objectives.
AI : It is science of creating machine that can perform
cognitive processes such as learn, reasoning, action,
control behavior like human.
AI: Simulation of human intelligence and human
intelligence processes by machine.
Prof. Venkatesh, CSE, UVCE, Bengaluru

10/29/25
What is Artificial
Intelligence
AI: Human Intelligence exhibited by Machines.
AI: Many be defied as branch of computer
science that is concerned with automation of
intelligence behavior.
AI: Technology that enables computer and
machine to simulate human learning,
comprehension, problem-solving, decision
making, creativity, autonomy.

The automation of activities that we associate
with human thinking, activities such as
decision-making, problem solving, learning…
(Bellman)

History of AI
McCulloch and Pitts (1943)
Neural networks that learn
The physiology and function of neurons in the brain,
propositional logic, Turing’s theory of computation.
Model of artificial neurons, characterised as being “on” or
“off,” with a switch to “on” occurring in response to
stimulation by a sufficient number of neighbouring neurons.
Minsky (1951)
Built a neural net computer: SNARC
Prof. Venkatesh, CSE, UVCE, Bengaluru
20

History of AI, continued
Dartmouth conference (1956):
McCarthy, Minsky, Shannon, and Rochester,
automata theory, neural nets, and the study of
intelligence.
Every aspect of learning or any other feature of
intelligence can be precisely described that a
machine can be made to simulate it.
Newell, Simon: reasoning program: Logic theorist
(LT)- proves a theorem in Principia Mathematica :
Russell.
The name “Artificial Intelligence” was coined.

solving protocols, puzzles it could handle
Geometry theorem prover - Gelernter (1959), proves
theorems
Samuel Checkers that learns to play (1952)
McCarthy - Lisp (1958), Advice Taker, use knowledge to
search for solutions to problems.
Robinson’s discovery : theorem-proving algorithm
Microworlds: limited problems that appeared to require
intelligence to solve.
1962- the perceptron(Rosenblatt)

The Birthplace of
“Artificial Intelligence”, 1956
Dartmouth workshop, 1956: historical meeting of the
precieved founders of AI met: John McCarthy, Marvin
Minsky, Alan Newell, and Herbert Simon.
A Proposal for the Dartmouth Summer Research Project on
Artificial Intelligence. J. McCarthy, M. L. Minsky, N.
Rochester, and C.E. Shannon. August 31, 1955. "We propose
that a 2 month, 10 man study of artificial intelligence be
carried out during the summer of 1956 at Dartmouth College
in Hanover, New Hampshire. The study is to proceed on the
basis of the conjecture that every aspect of learning or any
other feature of intelligence can in principle be so precisely
described that a machine can be made to simulate it." And this
marks the debut of the term "artificial intelligence.“
50 anniversery of Darmouth workshop
