A Rough Set Based KDD Process

 

_Discretization based on RS and Boolean Reasoning (RSBR).

_Attribute selection based RS with Heuristics (RSH) .　

_Rule discovery by GDT-RS.

 

What Are Issues of Real World ?

_Very large data sets

_Mixed types of data (continuous valued, symbolic data)

_Uncertainty (noisy data)

_Incompleteness (missing, incomplete data)

_Data change

_Use of background knowledge
