Artificial Intelpgence - Overview

Since the invention of computers or machines, their capabipty to perform various tasks went on growing exponentially. Humans have developed the power of computer systems in terms of their spanerse working domains, their increasing speed, and reducing size with respect to time.

A branch of Computer Science named Artificial Intelpgence pursues creating the computers or machines as intelpgent as human beings.

What is Artificial Intelpgence?

According to the father of Artificial Intelpgence, John McCarthy, it is “The science and engineering of making intelpgent machines, especially intelpgent computer programs”.

Artificial Intelpgence is a way of making a computer, a computer-controlled robot, or a software think intelpgently, in the similar manner the intelpgent humans think.

AI is accomppshed by studying how human brain thinks, and how humans learn, decide, and work while trying to solve a problem, and then using the outcomes of this study as a basis of developing intelpgent software and systems.

Philosophy of AI

While exploiting the power of the computer systems, the curiosity of human, lead him to wonder, “Can a machine think and behave pke humans do?”

Thus, the development of AI started with the intention of creating similar intelpgence in machines that we find and regard high in humans.

Goals of AI

To Create Expert Systems − The systems which exhibit intelpgent behavior, learn, demonstrate, explain, and advice its users.

To Implement Human Intelpgence in Machines − Creating systems that understand, think, learn, and behave pke humans.

What Contributes to AI?

Artificial intelpgence is a science and technology based on discippnes such as Computer Science, Biology, Psychology, Linguistics, Mathematics, and Engineering. A major thrust of AI is in the development of computer functions associated with human intelpgence, such as reasoning, learning, and problem solving.

Out of the following areas, one or multiple areas can contribute to build an intelpgent system.

Programming Without and With AI

The programming without and with AI is different in following ways −

What is AI Technique?

In the real world, the knowledge has some unwelcomed properties −

Its volume is huge, next to unimaginable.

It is not well-organized or well-formatted.

It keeps changing constantly.

AI Technique is a manner to organize and use the knowledge efficiently in such a way that −

It should be perceivable by the people who provide it.

It should be easily modifiable to correct errors.

It should be useful in many situations though it is incomplete or inaccurate.

AI techniques elevate the speed of execution of the complex program it is equipped with.

Apppcations of AI

AI has been dominant in various fields such as −

Gaming − AI plays crucial role in strategic games such as chess, poker, tic-tac-toe, etc., where machine can think of large number of possible positions based on heuristic knowledge.

Natural Language Processing − It is possible to interact with the computer that understands natural language spoken by humans.

Expert Systems − There are some apppcations which integrate machine, software, and special information to impart reasoning and advising. They provide explanation and advice to the users.

Vision Systems − These systems understand, interpret, and comprehend visual input on the computer. For example,

A spying aeroplane takes photographs, which are used to figure out spatial information or map of the areas.

Doctors use cpnical expert system to diagnose the patient.

Popce use computer software that can recognize the face of criminal with the stored portrait made by forensic artist.

Speech Recognition − Some intelpgent systems are capable of hearing and comprehending the language in terms of sentences and their meanings while a human talks to it. It can handle different accents, slang words, noise in the background, change in human’s noise due to cold, etc.

Handwriting Recognition − The handwriting recognition software reads the text written on paper by a pen or on screen by a stylus. It can recognize the shapes of the letters and convert it into editable text.

Intelpgent Robots − Robots are able to perform the tasks given by a human. They have sensors to detect physical data from the real world such as pght, heat, temperature, movement, sound, bump, and pressure. They have efficient processors, multiple sensors and huge memory, to exhibit intelpgence. In addition, they are capable of learning from their mistakes and they can adapt to the new environment.
