Applications

Autonomous planning & scheduling:
     NASA’s remote Agent program-control the operation of spacecraft.
Game playing:
    IBM’s Deep Blue-program to defeat in chess match.
Autonomous control:
    AlVINN- computer vision system to steer a car.
Diagnosis:
     Medical diagnosis program based on probabilistic analysis-to perform at the level of an expert physician.
Logistics Planning:
       U.S forces deployed a Dynamic Analysis and Replanning Tool (DART) to do automated logistics planning and scheduling for transportation. 
Robotics:
    Many surgeons now use robot assistants in micro surgery- creates 3D model of a patient’s internal anatomy.
Language understanding and problem solving:
    PROVERB-computer program that solves crossword puzzle-word filters.


Rational agent

Rational behavior: doing the right thing
The right thing: that which is expected to maximize goal achievement, given the available information.
An agent is something that acts.
Computer agent are expected to have other attributes,
        Operating under autonomous control,
         Perceiving their environment,
         Adapting new change.

An agent is an entity that perceives and acts.
A rational agent is one that acts so as to achieve the best outcomes or when there is uncertainty, the best expected outcome.
Making correct inference is a part of being a rational agent.
To act rationally is to reason logically to the conclusion that a given action will achieve one’s goal.

cognitive modeling

    Cognitive science is the interdisciplinary scientific study of how information concerning faculties such as perception(sense), language, reasoning, and emotion, is represented and transformed in a (human or other animal) nervous system or machine (e.g., computer). 
Thinking rationally: "laws of thought" :
     
Statement:
                Socrates is a Man.
                All men are mortal.
Conclusion:
              Socrates is Mortal.
These laws of thought were supposed to govern the operation of the mind ,their study initiated the field called logic.

Capabilities of computer

Natural language processing: to enable it to communicate successfully in English.
Knowledge representation: to share what it knows or hears.
Automated reasoning: to use the stored information to answer question and to draw new           
                                               conclusions;
Machine learning: to adapt to new circumstances and to detect and extrapolate patterns. 
  Computer vision: to perceive objects 
  Robotics: to manipulate objects and move
 

Definition

Definition:
   The art of creating machines that perform functions that require intelligence when performed by people.
   The study of how to make computers do things at which at moment people are better.
   The study of the computation that make it possible to preceive,reason and act.

Artificial Intelligence

Learning of making the computer Think better.
Defines the study and design of Intelligent Agent.
It plays the important role in the present era,contains natural language processing,knowledge representation,automated reasoning and machine learning.
The additional capability od a agent has computer vision and robotics.
