Question 12

+2 marksOne correct option

Which of the following statements about GraphSAGE and GAT (Graph Attention Network) is true?

  1. A

    GraphSAGE uses attention mechanisms to aggregate information from neighboring nodes

  2. B

    GraphSAGE is a node-level representation learning algorithm, while GAT is an edge-level representation learning algorithm

  3. C

    GAT assigns different importance weights to neighboring nodes during aggregation based on their relevance to the target node

  4. D

    GraphSAGE is a edge-level representation learning algorithm, while GAT is an node-level representation learning algorithm
