Improved Double-Layer Structure Multilabel Classification Model via Optimal Sequence and Attention Mechanism

Algorithm 1

	Input label values to construct a label map with weights:
	Input
	Output: G
(1)	G  {}
(2)	G.V  Y
(3)	For each (u, ) in G.V
(4)	Calculate the mutual information of MI (u, ) according to Definition 1.
(5)	G.E  MI (u, )
(6)	G  G(V, E)
(7)	Return G
