To eliminate such inconsistency, in this study we propose a novel Quasi-Wasserstein (QW) loss with the help of the optimal transport defined on graphs, leading to new learning and prediction paradigms of GNNs.

Making the parameters of the ROT problem learnable, we develop a family of regularized optimal transport pooling (ROTP) layers.

Global pooling is one of the most significant operations in many machine learning models and tasks, whose implementation, however, is often empirical in practice.
