Message passing

As explained in Machine Learning Algorithms in Depth

Message passing is a graph-computation technique in which nodes exchange information with neighboring nodes to update their representations.

Message passing is a graph-computation technique in which neighboring nodes exchange information so graph neural networks can update node representations and capture dependence relationships. section 11.5 section 11.7

Message passing supports graph-based learning tasks involving relational structure:

  • Modeling social networks, where relationships between nodes carry predictive information. section 11.5
  • Predicting protein structure, where graph representations encode relationships among components. section 11.5
  • Building graph neural network variants such as graph convolutional, graph attention, and graph recurrent networks. section 11.5 section 11.7

How Machine Learning Algorithms in Depth covers it

How deep it goes
Defines message passing as dependence capture between graph nodes but stops short of update equations, derivation, or implementation.
Examples
Uses social-network modeling and protein-structure prediction as graph-data applications.
How it connects
Connects graph neural networks with graph convolutional, graph attention, and graph recurrent networks.
