 Intelligence is the ability to learn about, learn from,
  understand, and interact with one’s environment.
 This general ability consists of a number of specific
  abilities, which include these specific abilities:
     Adaptability to a new environment or to changes in the current
      environment
     Capacity for knowledge and the ability to acquire it
     Capacity for reason and abstract thought
     Ability to comprehend relationships
     Ability to evaluate and judge
     Capacity for original and productive thought

 AI is the study of how to make computers do things which, at the
  moment, people do better
 AI is a branch of computer science concerned with teaching
  computers to think
 The capability of a device to perform functions that are normally
  associated with human intelligence, such as reasoning and
  optimization through experience
 AI is the branch of computer science concerned with the study and
  creation of computer systems that exhibits some form of
  intelligence-
       Learn new concepts and tasks
       Can reason and draw useful conclusion
       Can understand a natural language
AI                                       HI
   AI, when given the information can be  When HI is given the same
    exact, every time with speed.           information, it can not be as exact, and
   AI are digital                          is slower.
   AI uses byte-addressable memory.       HI are analogue
                                           The HI uses content-addressable
   There is a appealing hardware/software memory
    distinction obscures in AI
                                           No hardware/software distinction can
                                            be made with respect to the brain or
                                            mind
   Processing and memory are performed Processing and memory are performed
    by the different components.            by the same components in the brain
   AI could do this if it was program to
                                           Human intelligence can forget and lose
    do so, but this would be counter-
    productive.                             information

 This assumption was given by Newell and simon.
 They call this assumption the physical symbol system
  hypothesis.
 They define a physical symbol system as follows:-
    A physical symbol system consists of a set of entities called symbols, which
    are physical patterns that can occur as components of another type of entity
    called an expression or symbol structure. A symbol structure is composed of
    a number of instances (or tokens) of symbols related in some physical way.
    At any instance of time the system will contain a collection of these
    symbols structures. Besides these structures ,the system also contains a
    collection of processes that operate on expressions to produce other
    expressions: processes of and destruction.
 A physical symbol system is a machine that produces
  through time an evolving collection of symbol
  structures.
 This hypothesis is only a hypothesis.
 There appears to be no way to prove or disprove it on
  logical grounds.
 The only way to determine its truth is by
  experimentation.
   An AI technique is a method that exploits knowledge that should
    be represented in such a way that:
     The knowledge captures generalization.
     It can be understood by people who must provide it.
     It can easily be modified to correct errors and to reflect changes
      in the world and in our world view.
     It can be used in a great many situations even if it is not totally
      accurate or complete.
     It can be used to help overcome its own sheer bulk by helping to
      narrow the range of possibilities that must usually be considered.
   “What is our goal in trying to produce programs that do the
    intelligent things that people do?”
       Are we trying to produce programs that do the tasks the same way people
        do?
       Are we attempting to produce programs that simply do the task in
        whatever way appears easiest?
 Efforts to build programs that perform tasks the way
  people do can be divided into two classes:-
 In first class:-
   Programs that attempt to solve problems that do not
    really fit our definition of an AI task.
   They are problems that a computer could easily solve.
   Although that easy solution would exploit mechanisms
    that do not seem to be available to people.
   In second class:-
     Programs that attempt to model human performance are those
      that do things that fall more clearly within our definition of AI
      tasks.
     They do things that are not trivial for the computers.
     There are several reasons one might want to model human
      performance at these sorts of tasks:
       To test psychological theories of human performance

       To enable computers to understand human reasoning

       To enable people to understand computer reasoning

       To exploit what knowledge we can glean from people.
 In 1950,Alan Turing proposed the method for determining
  whether a machine can think.
 This method is known as Turing test.
 To conduct this test, we need
       2 people
       1 machine
 One person plays the role of the interrogator, who is in a separate
  room from the computer and the other person.
 The interrogator can ask questions of either the person or the
  computer by typing questions and receiving typed responses.
 The interrogator knows them only as A and B
 The goal of the machine is to
  fool the interrogator into
  believing that it is the person.
 If the machine succeeds at
  this, then we conclude that
  the machine can think.
