 Turing Test in Artificial Intelligence


 Alan Turing (computer scientist) introduce the Turing test in 1950. Turing test is used to determine whether or not a computer (machine) can think intelligently like humans?
Visualize a game of three players having two humans and one computer, an interrogator (as a human) is isolated from the other two players. The interrogator's job is to try and figure out which one is human and by asking questions from both of them. The interrogator is limited to a response to written questions to make the determination.
The chat between interrogator and computer would be like this:
A) Interrogator: Are you a computer?
B) computer: No.
If a human interrogator wouldn't be able to distinguish to answer provided by both human and computer, then the computer passes the test, and the machine(computer) is considered as intelligent as a human.
But in the year 1980, Mr. Johan Searle proposed the Chinese room argument. He argued that the Turing test couldn't be used to determine whether or not a machine is considered as intelligent as humans. He says that machines ELIZA and PERRY can easily pass the Turing test. 

History of Turing Test

The test is named after Alan Turing, who pioneered machine learning during the 1940s and 1950's papers called "computing machinery and intelligence and intelligence" while at the University of Manchester.

Variation And Alternatives To The Turing Test


Reverse Turing Test 

In this test, a human tries to convince a computer that it is not a computer or machine. For eg CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart).

Total Turing Test

Where the questionnaires can also test the perceptual ability to manipulate objects.

Minimum Intelligent Signal Test

Where only true/false and yes/no question is given. 

Alternatives to the Turing test were later developed because many see the Turing test to be flawed. These alternatives include tests such as 


 The Marcus Test  

in which a program that can watch a television show is tested by being asked meaningful questions about the show's content.

The Lovelace Test 2.0

which is a test made to detect the AI through examining its ability to create art.

Winograd Scheme Challenge 

It is a test that asks multiple-choice questions in a specific format.
It is proposed by  Hector Levesque.

A computer program called Eugene Goostman, which simulates a 13-year-old Ukrainian boy, is said to have passed the Turing test at an event organized by the university of reading.

Block Diagram of Computer|| Basic Explanation

By
A typical computer system irrespective of its size, class or type consists of hardware and software, integrated and synchronized together to perform computational work or data processing. Computer anatomy is concerned with the way the various functional units operate and how they connected together to form the computer system. A computer system consists of the following functional units : 1)  Input unit 2) Memory/Storage unit 3) CPU(central processing unit) 4) Output unit

Types Of Computer System || Analog Hybrid and Digital Computer System

By
Types of computer There are various methods on which computers can be classified. The classification may depend upon the size, technology, area, of application, type of data processed, etc. Generally, computers are divided into three main parts, These three are followings: Analog computers Hybrid computers Digital computers Analog computers An  analog computer  or  analogous computer  is a form of  computer  that uses the continuously changeable aspects of physical phenomena such as  electrical ,  mechanical , or  hydraulic  quantities to  model  the problem being solved.  Analog computers are computers that work on continuous data. Analog computers are used to measure physical quantities like pressure, temperature, speed, etc. Analog computers were widely used in scientific and industrial applications where digital computers of the time lacked sufficient performance. Analog computers c...

Components of Computer System

By
A system is defined as a set of interacting elements, responding to inputs so as to produce outputs. The computer system also consists of the following elements or components. Software Hardware Firmware Humanware   Software All the intangible components of the computer system are known as software In other words, we can say that all computer programs and applications run behind the monitor screen, are known as software. Computer software is a term that describes computer programs. Example   Microsoft-windows (all operating system software) and notepad, MS office suite, window media player(application software). Software is further divided into two parts these are following 1) system software 2) application software Hardware All tangible component of a computer system is known as hardware. In other words, computer hardware is the collection of physical parts of the computer system. Example  CPU(Microprocessor), monitor, keyboard,...
