CONCEPT LEARNING

 

CONCEPT LEARNING

·       Learning involves acquiring general concepts from specific training examples.

·       Example: People continually learn

·       general concepts or

·       categories such as

ü  "bird,"

ü  "car,"

ü  "situations in which I should study more in order to pass the exam," etc.

·       Each such concept can be viewed as

·       describing some subset of objects or events

ü  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
