Purpose of AI:
To increase man’s understanding, reasoning, learning and perception for building new developmental tools.
Knowledge based program that provides expert quality solutions to problems in a specific domain
Knowledge update facility
Exhibit expert performance
Have high level of skill
Have adequate robustness
Represent knowledge symbolically
Reformulate symbolic knowledge
handle difficult problem domains
use complex rules
Examine its own operation
Search mechanism based on the Darwinian principle of natural evolution
ARTIFICIAL NEURAL NETWORKS
Information processing systems which are constructed and implemented to model the human brain
OBJECTIVE OF ANN
To develop a computational device for modeling the brain to perform various computational tasks at a faster rate than the traditional systems
THE MAIN PROPERTY OF ANN IS ITS CAPABILITY TO LEARN
The learning is performed with the help of teacher.
The correct target output values are known for each input pattern
self organizing in which exact clusters are formed by discovering similarities and dissimilarities among the objects
learning with a critic as opposed to learning with a teacher
Technique to deal with imprecision and information granularity
Widely used in non-linear, time varying, ill-defined systems, complex systems like
