What is AI?

 

Reply:

Artificial intelligence (AI) is the intelligence exhibited by machines or software. It is also the name of the academic field of study which studies how to create computers and computer software that are capable of intelligent behavior.

Strong AI (a machine with consciousness, sentience, and mind): The idea behind Strong AI is that the machines could represent human minds in the future. If that is the case, those machines will have the ability to reason, think and do all functions that a human is capable of doing.  Nanobots, which can help us fight diseases and also make us more intelligent, are being designed. The development of an artificial neural network, which can function as a proper human being, is being looked at as a future application of Strong AI.

Weak AI or “narrow” AI: The idea behind Weak AI is the fact that machines can be used to act as if they are intelligent. For example, when a human player plays any game against a computer, the human player may feel as if the computer is actually making impressive moves. But the game application is not thinking and planning at all. All the moves it makes are previously fed into the computer by a human and that is how it is ensured that the software will make the right moves at the right times.

 

What are the different Applications where AI can be utilized?

Reply:

Here are some.

game playing

speech recognition

understanding natural language

computer vision

expert systems

heuristic classification etc

 

Which Language is Best for Artificial Intelligence?

Reply:

Python. Python is one of the most widely used programming languages in the AI field because of its simplicity. …

Java. Java is also the best choice.

Lisp.

Prolog.

C++
