WebDIFFPOOL learns a differentiable soft cluster assignment for nodes at each layer of a deep GCNN, mapping nodes to a set of clusters, which then form the coarsened input for the next GNN layer. Websuch a pooling layer. Unlike DiffPool, which attempts to do this via computing a clustering of the Nnodes into dkNe clusters (and therefore incurs a quadratic penalty in storing cluster assignment scores), we leverage the recently proposed Graph U-Net architecture [1], which simply drops Nd kNenodes from the original graph.
