5. CONCEPT LEARNING
· Learning
involves acquiring general concepts from specific training examples. Example: People
continually learn general concepts or categories such as "bird,"
"car," "situations in which I should study more to pass
the exam," etc.
· Each
such concept can be viewed as describing some subset of objects or events
defined over a larger set
· Alternatively,
each concept can be thought of as a Boolean-valued function defined over this larger
set. (Example: A function defined over all animals, whose value is true for
birds and false for other animals).
Definition: Concept
learning - Inferring a Boolean-valued function from training examples of its
input and output
