edge_weight and mi loss

[jiashizuo]

Thank you so much for sharing the work!but I have some doubts about the following points:

Do we not need to take the negative of the mutual information loss?Should we be minimizing the mutual information loss?

Also, in the GlobalGNN module, the calculated edge_weight does not seem to be used.

I look forward to your explanation！

非常感谢你的代码，很棒的工作！但是我对下面的几点有些疑惑，互信息损失不用取负吗，是最小化互信息损失吗，还有在globalgnn模块，所求的edge_weight，好像没有用上？期待你的解答~
