As an inheritance from traditional CNNs, most approaches formulate graph pooling as a cluster assignment problem, extending the idea of local patches in regular grids to graphs. Despite the wide adherence to this design choice, no work has …
Graph pooling中的方法
Did you know?
WebPooling is nothing other than down sampling of an image. The most common pooling layer filter is of size 2x2, which discards three forth of the activations. Role of pooling layer is to reduce the resolution of the feature map but retaining features of the map required for classification through translational and rotational invariants. WebDec 23, 2024 · 图神经网络有两个层面的任务:一个是图层面(graph-level),一个是节点(node-level)层面,图层面任务就是对整个图进行分类或者回归(比如分子分类),节点层面就是对图中的节点进行分类回归(交通网络道路流量预测)。对于图层面的任务,我们需要聚合图的全局信息(包括所有节点和所有边 ...
