Pytorch Geometric Review 4 - Temporal GNN

( 참고 : https://www.youtube.com/c/DeepFindr/videos )

Temporal GNN

ex) Traffic Forecasting

2개의 dimension

• (1) temporal 축
• (2) spatial 축

[ Temporal GNN은 크게 2 step으로 이루어진다. ]

step 1) GNN model

• 매 time stamp마다의 정보를 GNN으로 보낸다.

step 2) Temporal model

• GNN을 통해 임베딩된 벡터들이, temporal model를 거치게 된다

Packages : pytorch geometric temporal

ex) T-GCN

ex) graph multi-attention network

ex) temporal graph network for dynamic graph

node / edge가 dynamic하게 변화 ( 추가/삭제 가능 )
