同样,Transformer的公式整理一下也可以变成 h_i^{l+1} := \delta(\sum_{j \in S}(A^lh_j^l)) 。因此,两者公式实际上是类似的。当Graph是全连接图时,那么GNN的节点公式实际上等同于Transformer的节点公式(因为Transformer关注每一个单词对当前单词的影响)。因此,Transformer实际上就是可以看成全连接的GAT。

To address these issues, researchers are exploring new architectures, learning strategies, and efficient data preprocessing methods. GNNs have emerged as a prominent approach in this area, leveraging the geometric structure of point clouds to maintain data integrity while enhancing feature extraction, ...
