5. What is AI?
Programs that behave externally like humans?
Programs that operate internally as humans do?
Computational systems that behave intelligently?
Rational behavior?
6. ARTIFICIAL INTELIGENCE
INTELIGENCE
Intelligence: “The capacity to learn and solve problems”
Artificial Intelligence: Artificial intelligence (AI) is the simulation of human
intelligence by machines.
• The ability to solve problems
• The ability to act rationally
• The ability to act like humans
7. • Human beings are
intelligent
• To be called
intelligent, a
machine must
produce responses
that are
indistinguishable
from those of a
human
8. 8
Program has common sense
if it automatically deduces for
itself
our ultimate objective is to
make programs that learn
from their experience as
effectively as humans do.
HISTORY

10. The overall research goal of artificial intelligence is to
create technology that allows computers and machines
to function in an intelligent manner
11.
12. The overall research goal of artificial intelligence is to create technology that allows computers and
machines to function in an intelligent manner. The general problem of simulating (or creating)
intelligence has been broken down into sub-problems.
13. Reasoning, problem solving :
Researchers developed algorithms that imitated step-
by-step reasoning that humans use when they solve
puzzles or make logical deductions.
Knowledge representation :
Knowledge representation and knowledge
engineering are central to AI research. Many of the
problems machines are expected to solve will require
extensive knowledge about the world.
14. Planning :
Intelligent agents must be able to set goals and achieve them. This calls for an
agent that can not only assess its environment and make predictions, but also
evaluate its predictions and adapt based on its assessment.
Learning :
Machine learning, a fundamental concept of AI research since the field’s
inception, is the study of computer algorithms that improve automatically through
experience. Unsupervised learning is the ability to find patterns in a stream of input.
Social intelligence :
Affective computing is the study and development of systems that can recognize,
interpret, process, and simulate human affects.
Creativity :
A sub-field of AI addresses creativity both theoretically and practically .
General intelligence :
Many researchers think that their work will eventually be incorporated into a
machine with artificial general intelligence, combining all the skills mentioned above
and even exceeding human ability in most or all these areas.

daily human lives today and
it assists in almost every
scenario whether you realize
it or not
Automated customer support
18. 18
The online shopping platform you use collects and
stores lots of information about your usage — whether
you like it or not.
Healthcare Intelligence
healthcare, artificial intelligence has already
proved to be a game-changer, improving every
part of the industry virtually.
19. 19
Collaboration of finance industry and artificial
intelligence is a perfect match.
Smart cars and drones
When it comes to AI applications, you can hardly get a
more prominent and better demonstration of the
technology than what smart cars, as well as drone
manufacturers, are accomplishing with it.

Presentation Overview
27. Definition of Robotics
A robot is…
“An active artificial agent whose environment is the
physical world”
--Russell and Norvig
“A programmable, multifunction manipulator designed
to move material, parts, tools or specific devices
through variable programmed motions for the
performance of a variety of tasks”
--Robot Institute of America

31. Classical architecture
◦ shortcomings
Behavior-based architecture
Sensors
Reason about behavior of objects
Identify objects
Build maps
Avoid objects
Actuators

32. Emotions
Energy-efficiency
Integration
◦ Hierarchy of information representation
Control structures
◦ Synthesis of neural nets and fuzzy logic
Robotic surgery
◦ Telepresence
Robot perception
◦ Face and object recognition
33. Emotions help prevent people from repeating
their mistakes (decisions that resulted in
negative feelings)
Recognizing emotions would allow robots to
become more responsive to users’ needs
Exhibiting emotions would help robots
interact with humans
34. Decides proper emotional
response to stimuli and
exhibits corresponding
facial expression, body
posture, and vocal quality
Behavioral response
serves either social or
self-maintenance
functions

oil from an external
bladder to its
reservoir, making

enough to sink
To dive, small motor
pushes battery pack
into nose
Process is reversed to
ascend
