LISP PROLOG
LISP It is derived from “List Processing” It is an Expression oriented language., It is an important language for AI
programmers.Syntax ::
S-expressions (Symbolic expressions)(car (cons A B))
M-expressions (Meta Expressions)car[cons[A,B]]
PICTURES :
Prolog is a general purpose logic programming language associated with AI and computational linguistics.
In Prolog, program logic is expressed in terms of relations, and a computation is initiated by running a query over these relations.
PROLOG.,
1. An atom, whose meanings is not defined.2. Numbers can be floats or integers.3. Variables are strings consisting of letters, numbers and underscore characters, and beginning with an upper-case letter or underscore(_).
Prolog Data types,.
PROLOG
o Logical language
o Specific uses
o Smaller language,
easier to learn
LISP
o Functional language
o General purpose
o Handles wide variety
of tasks, easier to use
Differences b/w LISP & PROLOG,
APPLICATIONS.,
AI and Hollywood Movies. Smart Car. Applications of Expert Systems.
» In today’s generation, Hollywood movies are mostly about androids, humanoids, and robots.
» Machines going out of control.
» Replacing humanity.
» World domination.
AI and Hollywood Movies
» Speech Recognition.
» Up-to-date information about historical landmarks and points of interest on the car’s rout.
» Lowest price gas stations close to the current position of the car.
» Warns drivers of road hazards.
Smart Car
DENDRAL: Used to identify the structure of chemical compounds. First used in
1965.
LITHIAN: Gives advice to archaeologists examining stone tools.
Applications of Expert System
PROS & CONST’so Advantageso Disadvantageso Difference b/w AI & NI
It can help improve our way of life.
Machines will be able to do jobs that require detailed instructions.
Use robots for heavy construction, military benefits, or even for personal assistance at private homes.
There will be less injuries and stress to human beings.
Mental alertness and decision
making capabilities.
Advantages:
o Limited Abilityo Slow Real Time Responseo Can’t Handle Emergency
Situationo Difficult codeo High Cost
Disadvantages:
» Non Creative
» Precise
» Consistency
» Multitasking
Differences b/w AI & NI
» Creative
» May contain Error
» Non consistent
» Cant handle
