category learning, concept attainment  based on Jerome Bruner.
 
"t<b>he search for and listing of attributes that can be used to distinguish </b>
<b>exemplars from non exemplars of various categories</b>
 
<b>concepts are the mental categories that help us classify objects, events, or ideas and </b>
<b>each object, event, or idea has a set of common relevant features</b>. 
Thus, concept learning is a strategy which requires a learner 
to compare and contrast groups or categories that contain concept-relevant features with 
groups or categories that do not contain concept-relevant features.
 
this task is known as <b>LEARNING FROM EXAMPLES</b> ....
 
Prototype Theory of Concept Learning
people abstract out the<b> central tendency (or prototype) of the experienced examples</b>, 
and use this as a basis for their categorization decisions.
 
Example:  SPORTS =  football, baseball, bowling, tennis etc.
 
semantic similarity to a central example
 
Defn:  an athletic activity requiring skill or phsy prowess and often competitive.
 
BUT  look at the list of semantically related items:
at the tail end are cooking, walking, Gatorade, protein, sports drink.
