A graph network takes a graph as input and returns a graph as output. The input graph has edge- (E ), node- (V ), and global-level (u) attributes. The output graph has the same structure, but updated attributes. Graph networks are part of the broader family of "graph neural networks" (Scarselli et al., 2009).
講直白一些，就是用神經網絡處理圖，輸入是圖，輸出也是圖。以前都是處理向量(Vector)，所以NLP中需要做Word2Vec後才能運用深度學習的處理結果。作者們認爲 Graph2Graph 是讓神經網絡具備推理(Reason)能力的一個關鍵步驟。
