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

Algorithm 2
Constructing the minimum spanning tree of labels based on Algorithm 1:
Input: G (V, E)
Output: MWT
(1)MWT  {}
(2)For G, then V is:
(3) Make the set ()
(4)For (u, ) in G. E is ordered according to weight (u, ) via an increasing way:
(5) If set(u)  set():
(6)  MST = MST  {(u, )}
(7)  Let it Union (u, )
(8)Return MWT  MST
