两路并行 将GCN的卷积结果和S-LSTM(summary)和I-LSTM（interaction）

1. weighted graph convolution

2. graph-gather layers 经过一层全连接再加起来得到全图的全部信息（和）是表示graph-level的信息

3. 对gt做 graph-state的S-LSTM 也就是对summary graph-gate做 graph-level的LSTM

4. 对gXt和gYt进行连接，再对其做LSTM 就是interaction

5. 最后把得到的结果都concantenate起来 经过全连接 得到1*k的向量 k表示标注交集的label数。

这个工作得到的都是graph-level的结果，我们也可以拓展到node-level去

Network embedding就是通过训练特征表示representation来使得图中相邻的节点表征尽可能小，而较远的节点表征尽可能大。或者使得特征表示满足其他的task相关的要求。

Network embedding aims to represent graph nodes in a low dimensional space where the network structure and properties are preserved.
