Risk Factors Discovery for Cancer Survivability Analysis Using Graph-Rule Mining

Algorithm 1

The proposed cluster-based algorithm for rule summarization.

	Input: clusters (, , , ), the number of selected rules , and the penalty terms of , , and ;
	Initialization:
	set the rule set to empty:
	for to do
	While ( or ) do
	Calculate the score of () according to equation (7)
	Select one rule with the highest score and label it as
	and removefrom
	end
	end
	Output: Return the optimal rules from .
