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。

Chapter 1 highlighted the key role played by data in a machine learning project. As we saw, training the learning algorithm on a larger quantity of high-quality data increases the accuracy of the model more than fine tuning or replacing the algorithm itself. In an interview about big data [...
In an agile, exploratory environment, the results of computations will evolve with the detection and extraction of more signals. Semi-structured NoSQL databases meet this need for flexibility: they provide enough structure to organize data, but do not require the exact schema of the data before ...
