We proposed one novel gated2 fusion strategy to mutually absorb useful and meaningful information of each point3 and its neighboring points to enrich its semantic representation. As in Eq. (2),gci4 and gi are determined by the representations of the each point and its neighboring5 ones. Table 1 (response letter) illustrates the11 modelcomplexitycomparisons. Table 4(the submitted paper)16 ablates thecontribution ofeach component, namely CR, AM and GPM. We are sorry for not providing clearer information in our manuscript.

We thank all the reviewers for your time in reviewing this paper and also for your suggestive comments. We will add detailed remarks if accepted. Y es, they are the same as the metrics used in the multi-label setting. Some typos to be corrected. They follow the same settings with the simulated study.
