We thank all reviewers for their encouraging and constructive feedback. The scores determine the order in which nodes are fused. The reviewer is correct that each Transformer layer in Fig.3 only outputs a feature embedding that is In Eq.2, the actions are produced by the final layer in Fig.3 is an illustration of The yellow part in Fig.4 is the same as Fig.3. We will add more detailed explanations about GNN's limitations on tracking global node dependencies. Y es, GO can be trained in an on-line scenario similar to Decima.
