2 Attention meets pooling in graph neural networks 注意力机制可以用在边上,也可以用在节点上,传统的 GAT 是用在边上,本文更关注于节点上的注意力机制。 注意力机制在CNN里一般用以下公式表达: Z=α⊙X(1)Z=α⊙X(1) 其中: X∈RN×CX∈RN×C代表输入; ...
事实上,无监督注意力的最佳模型(GIN with global pooling)与有监督注意力的类似模型(GIN, sup)之间的颜色分类精度差距-很大,超过60%。对于较大的三角形,这个差距是18%,而对于MNIST-75SP-NOISY,这个差距超过12%。与上界情况相比,这个差距甚至更大,这表明我们的监督模型可以进一步调整和改进。具有监督或弱监督注意...

The spatial encoder of TabularNet utilizes the row/column-level Pooling and the Bidirectional Gated Recurrent Unit (Bi-GRU) to capture statistical information and local positional correlation, respectively. For relational information, we design a new graph construction method based on the WordNet tree...

With the rapid developments in science and technology and the continuous iteration of hardware equipment, artificial intelligence is being widely used in various fields (such as security monitoring, medical assistance, health diagnosis, intelligent recommendation, remote sensing monitoring, and target locatio...
It was originally developed for the ImageNet VID challenge introduced in ILSVRC2015. It contains components such as region proposal, still-image object detection, generic object tracking, spatial max-pooling and temporal convolution.
