Bo Jiang, Ziyan Zhang, Doudou Lin, Jin Tang. In addition, GAOs belong to the family of soft attention, instead of hard attention, which has been shown to yield better performance.

Attention operators on graph data enables learnable weights when aggregating information from neighboring nodes. Data Representation and Learning with Graph Diffusion-Embedding Networks.

hGAO uses the hard attention mechanism by attending to only important nodes. Graph Representation Learning via Hard and Channel-Wise Attention Networks. 2019 KDD. Graph Representation Learning via Hard and Channel-Wise Attention Networks Attention operators have been widely applied in various fields, including computer vision, natural language processing, and network embedding learning.

In this work, we propose novel hard graph attention operator~(hGAO) and channel-wise graph attention operator~(cGAO). Hongyang Gao, Shuiwang Ji. 3.1 Hard Graph Attention Operator Graph attention operator (GAO) consumes excessive computation resources, including computational cost and memory usage, when graphs have a large number of nodes, which is very common in real-world applications. Learning convolutional neural networks for graphs. Hongyang Gao, Shuiwang Ji. Convolution. CVPR 2019. paper. Boris Knyazev, Graham W. Taylor, Mohamed R. Amer.

However, graph attention operators (GAOs) consume excessive computational resources, preventing their applications on large graphs.
