任务:多跳问答
动机:GNN 信息传播太乱了,而且会有多余的两类传播信息:For a GNN where nodes represent sentences, the following message passing is unnecessary and may suppress the disturbance from useless nodes: (1) from the latter node to the former node, (2) a node haven’t received the message from question but it updates other nodes. 本文要让信息传播 the message only starts from the question and then passes to the latter sentence nodes hop by hop,很符合直觉的想法。
