Graph pooling作用
Did you know?
WebApr 17, 2024 · In this paper, we propose a graph pooling method based on self-attention. Self-attention using graph convolution allows our pooling method to consider both node features and graph topology. To ensure a fair comparison, the same training procedures and model architectures were used for the existing pooling methods and our method. WebAlso, one can leverage node embeddings [21], graph topology [8], or both [47, 48], to pool graphs. We refer to these approaches as local pooling. Together with attention-based mechanisms [24, 26], the notion that clustering is a must-have property of graph pooling has been tremendously influential, resulting in an ever-increasing number of ...
