WebJul 20, 2024 · Diff Pool 与 CNN 中的池化不同的是，前者不包含空间局部的概念，且每次 pooling 所包含的节点数和边数都不相同。. Diff Pool 在 GNN 的每一层上都会基于节点的 Embedding 向量进行软聚类，通过反复堆叠（Stacking）建立深度 GNN。. 因此，Diff Pool 的每一层都能使得图越来越 ... WebMix Pooling：基于最大池化和平均池化的混合池化。 Power average Pooling：基于平均和最大化的结合，幂平均(Lp)池化利用一个学习参数p来确定这两种方法的相对重要性；当p=1时，使用局部求和，而p为无穷大时，对应max-pooling。
