图嵌入emdedding methods

图嵌入论文阅读：
Embedding methods,learn free-parameter node embeddings in a transductive manner,thus do not generalize to unseen nodes and networks.
这句话应该如何理解。

你去查一查吧，图网络分为 transductive 和 inductive 的形式。

Transduction is reasoning from observed, specific (training) cases to specific (test) cases.

Induction is reasoning from observed training cases to general rules, which are then applied to the test cases.

Transductive 形式的图网络学习不能适用于 general 的图，也就不能用于 unseen 的节点和网络。
