Artificial intelligence (AI) is concerned with building machines that can act and react appropriately to demands. The document discusses the history of AI from early developments focusing on modeling the human brain to modern language processing programs. It also outlines some of the key problems in AI like deduction, reasoning, problem solving, and natural language processing. Tools used in AI development include search and optimization, logic, neural networks, and specialized programming languages. Applications of AI include medical diagnosis, robot control, scientific discovery, and more.

1. Artificial Intelligence(AI)ByK.ArunkumarAIT-07-002

2. Intelligence:“Intelligence is the name we give to the data processing activity of entities which respond to information with behaviour which appears to be intended to be optional with respect to pre-set goals”.The Ability to:Learn and adapt from experience.Use knowledge to make decisions.Problem solve.Show CreativityHandle and manipulate language

3. AI:“Artificial intelligence is concerned with building machines that can act and react appropriately, adapting their response to the demands of situation.”

4. History:Earlier developments(1940-65)In the beginning the focus of AI research was on modelling the human brain. Research shifted to using games like noughts and crosses, chess etc to create “AI” systemsThese games were effective as they had limited problem domains.The games also had a number of rules that were easy to define.Then the focus shifted to language processing.......

5. Language Processing (1965-1975)ELIZA (1966)1st language processing programResponded to users inputs by asking questions based on previous responses.PARRY (1972)Parry modelled a conversation with a paranoid personThis seems odd but the program was created by a psychiatrist SHRDLU (1970)The program could interpret verbal commands to move coloured blocks."Move the red block behind the green one“ It could understand and carry out the instruction.Chatter bots??

6. Problems of AI:1.Deduction, reasoning, problem solving eligible>18<18noyes2.knowledge representation3. Planning 4. Natural language processing

7. Motion and manipulation.Perception.Social intelligence.Creativity.General intelligence.

8. Tools of AI:Search and optimization:Many problems in AI can be solved in theory by intelligently searching through many possible solutions: Reasoning can be reduced to performing a search. LogicNeural networksSpecialized languagesIPL
