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. WebDIFFPOOL (Ying et al., 2024) is a differentiable graph pooling module that can be adapted to various GNN architectures in a hierarchical and end-to-end fashion. DIFFPOOL learns …
