Artificial Intelligence Interview Questions

1.    What is Artificial Intelligence?

Artificial Intelligence is the field of computer science that highlights the construction of intelligent machine that performs and reacts like individuals.

2.   What is an artificial intelligence NeuralNetworks?

Artificial intelligence Neural Networks are composed of multiplebnodes, which imitate biological neurons of human brain, empowering the machinento think and learn the same way the human’s do- making them fit for seeingbthings like speech, objects and animals like we do.

3.   What are the various areas where AI (Artificial Intelligence) can be used?

Artificial Intelligence can be used in several areas like Computing, Bio-informatics, Speech recognition, Humanoid robot, Space, Computer software and Aeronautics’s etc.

4.   What is Prolog in AI?

Prolog in AI is a programming language based on logic.

5.   Give an explanation on the difference between strong AI and weak AI?

Strong AI: It makes solid claims that computers can be made to think on a level equivalent to humans
Weak AI: It predicts that some features that resemble to human intelligence can be united to computer to make it more useful tools.

6.   Mention the difference between statistical AI and Classical AI?

Statistical AI: It is concerned with “inductive” thought like given a set of pattern, induce the trend etc.
Classical AI: It is more concerned with “deductive” thought given as a set of constraints, deduce a conclusion etc.

7.   What is alternate, artificial, compound and natural key?

Alternate Key: All candidate keys are known as Alternate Keys except primary keys
Artificial Key: If no key either stands alone, then the last resort is to, simply create a key, by assigning a number to each record. This is known as artificial key.
Compound Key: When there is no single data element that exclusively defines the existence within a construct, then integrating various elements to create a unique identifier for the construct is known as Compound Key.
Natural Key: Natural key is one of the data elements that is stored within a construct and is used as the primary key.

8.  Which is the best way to go for Game playing problem?

Heuristic approach is the best way to go for game playing issue, as it will use the method based on intelligent guesswork. For e.g. Chess between humans and computers as it will use brute force computation, looking at hundreds of thousands of positions.

9.   What is agent in artificial intelligence?

Anything identifies its environment with the use of sensors and acts upon an environment by effectors are known as Agent. Agent includes Programs, Robots and Humans etc.

10.  What does Partial order or planning involve?

In partial order, rather than searching over possible situation it includes searching over the space of possible plans.  The idea is to construct a plan piece by piece.

11.  What are the two different kinds of steps that we can take in constructing a plan?

Steps:
1.   Add an operator (action)
2.   Add an ordering constraint between operators

12.  When an algorithm is considered completed?

An algorithm is completed when it dismisses with a solution when one exists.

13.  What is a heuristic function?

A heuristic function ranks alternatives, in search algorithms, at each branching step based on the available information to decide which branch to follow.

14.  What is “Generality” in AI?

Generality is the amount of ease with which the method can be modified to various domains of application.

15.  What is a top-down parser?

A top-down parser begins by guessing a sentence and logically predicting lower level constituents until individual pre-terminal symbols are made

16. What is Neural Network in Artificial Intelligence?


In artificial intelligence, neural network is an emulation of a biological neural system, which receives the data, processes the data and gives the output based on the algorithm and empirical data.
