Software Defect Prediction via Attention-Based Recurrent Neural Network

Algorithm 1

Parsing source files into ASTs’ vectors.

	Input: source files ,
	Representative nodes ;
	Output: ASTs’ vectors ;
(1)	for do
(2)	=  constructing from ;
(3)	Traversing in by DFT;
(4)	If in S then
(5)	Adding node into ;
(6)	end
(7)	Adding into V;
(8)	end
(9)	return V;
