Each role-dependent recurrent unit BLSTM rolex receives corresponding inputs x i,rolex (i = [1, ..., N ]), which have been processed by an encoder model, we can rewrite 5and 6into 7and (8) respectively: + BLSTM role b (intent t,role b ).
v his = BLSTM rolea (CNN(utt t,rolea )) (8) each role-based contextual module focuses on modeling the role-dependent goal and speaking style, and v cur from (2) is able to carry role-based contextual information.
