performance how artificial intelligence

and machine works here in this diagram

you can see we categorize the human and

machine working in the four categories

system that thinks like human system

that think rationally system that act

like human and system that can act

rationally so system that act like human

like during test the art of creating

machines that perform functions that

requires intelligence when performed by

people this definition is given by

Croswell and the study of how to make

computers to do things at which at the

moment people are better this definition

is given by Rich and KN you enter a room

which has a computer terminal and you

have a fixed period of time time to type

what you want into the terminal and

study the

replies at the other end of this line is

either a human being or a computer

system if it is a computer system and at

the end of the period of time you cannot

reliably determine whether it is a

system or a human then the system is

deemed to be intelligent so system that

act like humans that means during test

approach where a human questions can

answering his questions via teletype the

computer Must Believe

intelligently intelligent Behavior to

human thinks cognitive science the

exciting new effort to make computers

think

machine with Minds in the full and

activities that we associate with human

thinking activities such as decision

making problem solving learning Etc so

now come to the approach where system

that think rationally so we have law of

thought human are not always rational

rational means defined in terms of logic

logic can't express everything that is

uncertainty logical approach is often

not feasible in terms of computation

time the study of mental facilities

through the use of computational models

the study of the computations that make

it possible to perceive reason and act

now we can now learn system that act

rationally logic only part of a rational

agent not all of rationality

sometimes logic cannot reason a correct

conclusion at that time some specific

human knowledge or information is used

thus it covers more generally different

situation of problems compensate the

incorrectly reason conclusion study AI

as rational agent so here are the two

advantages it is more General than using

logic only because logic plus domain

knowledge is more efficient it allows

extension of the approach with more

scientific methodologies so rational

agent so what is Agent an agent is an

entity that perceives an act the course

is about designing rational agent

abstractly an agent is a function that

percept history two actions here in this

we have for one formula which describes

function from P to a human as observed

from inside how do we know how human

think inpection versus psychological

experiment cognitive science the

exciting new effort to make computers

thinks machine with Minds in the full

and literal sense the automation of

activities that we associate with human

thinking activity such as decision

making problem solving and learning so

what is the goal of AI to make computers

more useful by letting them take over

dangerous or tedious task from

Human understand principle of human

intelligence the foundation of AI

philosophy at that time the study of

human intelligence begin with no formal

expression initiate the idea of Mind as

a machine and its internal operations

mathematics mathematics formalizes the

three main area of AI computation logic

and probability computations leads to

analyze the problems that can be

computed that is complexity Theory

probability contributed the degree of

including time sharing the link list

data type

Linguistics for understanding natural

knowledge representation the main topic

in AI artificial intelligence can be

considered under a number of headings

search which includes game playing

representing knowledge and reasoning

with it planning learning natural

disadvantage increased cost

difficulty with software development

slow and expensive few experienced

programmers few practical products have

reached the market as it search is the

fundamental techniques of

AI possible answers decisions or courses

of actions are structured into abstract

space which we then search search search

is either blind or uninformed blind

search in which we mve through the space

without worrying about what is coming

next but recognizing the answer if we

see it

informed we guess what is ahead and use

the informations to decide whether to

look

next we may want to search for the first

answer that satisfies our goal or we may

want to keep searching until we find the

best answer knowledge representation and

reasoning the second most important

Concept in artificial intelligence if we

are going to act rationally in our

environment then we must have some way

of describing that envirment and drawing

interfaces from that

representation how do we describe what

we know about the world how we describe

it consciously how do we describe it so

that we can get hold of the right piece

of knowledge when we need it how do we

generate New pieces of

knowledge how do we deal with uncertain

knowledge so in this diagram we have

knowledge as declarative and procedural

declarative knowledge deals with pionite

questions like what is the capital of

India procedural knowledge deals with

how procedural knowledge can be embedded

in declarative knowledge

planning given a set of goals construct

a sequence of actions that achieve these

goals

often very large search space but most

part of the world are independent of

most other parts often it start with

goals and connect them to the actions no

necessary connections between order of

planning and Order of

execution what happen if the world

changes as we execute the plan Andor our

action

doesn't produce the expected result

learning if a system is going to act

truly appropriately then it must be able

to change its action in the light of

experience how do we generate new fact

from old how do we generate New Concept

how do we learn to distinguish different

situation in new

environments in interacting with the

environment in order to enable

intelligent Behavior we will have to

interact with our envirment properly

intelligent systems may be expected to

accept sensory input like Vision sound

interact with humans interact with

humans understand language recognize

speech generate text speech and Graphics

modify the environment with using btics
