Graph unpooling
WebGiven a graph with features, the unpooling layer enlarges this graph and learns its desired new structure and features. Since this unpooling layer is trainable, it can be applied to graph generation either in the decoder of a variational autoencoder or in the generator of a generative adversarial network (GAN). We guarantee that the unpooled ... WebA decision region is an area or volume designated by cuts in the pattern space. The decision region, on the other hand, is the region of the input space that is allocated to a certain class based on the decision boundary and is where the classification algorithm predicts a given class. The area of a problem space known as a decision boundary is ...

[7] proposed graph U-Net with graph pooling and un-pooling operations. A graph pooling layer relies on train-able similarity measures to adaptively select a subset of n-odes to form a coarser graph while the graph unpooling lay-er uses saved information to reverse a graph to the structure before its paired pooling operation.
