MPNN framework standardizes different message passing models that were independently created by several researchers. The main idea of this ...

Oct 05, 2020 · A very simple example of message passing architecture for node V1. In this case a message is a sum of neighbour’s hidden states. The update function is an average between a message m and h1. Gif created by author. After all, the idea behind the MPNN is conceptually simple. Each node in the graph has a hidden state (i.e. feature vector).

GNN-based methods such as the message-passing neural network (MPNN)8 or the more recent D-MPNN12 and Attentive FP11 outperformed descriptor-based methods in almost all tasks. One drawback of the GNN is that to obtain sufficient accuracy, a large dataset is required for the prediction performance, and as such datasets are expensive to prepare,
