Method on Rough Set-Based Rule-Knowledge Acquisition

A method on rough set- based rule- knowledge acquistion was presented.It made use of rough sets theory to analyze data and inducted the possible rules.A probability- based optimal criterion was pre- sented and used to select the probability- optimal rules from those possible rules.The operation procedure was illustrated by an example.The result shows thatthe method is undoubtedly a new kind of investiga- tion on knowledge acquisition and can effectively solve the bottleneck problem.
