GNN-FiLM: Graph Neural Networks with Feature-wise Linear Modulation

Brockschmidt, Marc

Understand

This paper presents a new Graph Neural Network (GNN) type using feature-wise linear modulation (FiLM).

  • Many standard GNN variants propagate information along the edges of a graph by computing "messages" based only on the representation of the source of each edge.
  • In GNN-FiLM, the representation of the target node of an edge is additionally used to compute a transformation that can be applied to all incoming messages, allowing feature-wise modulation of the passed information.
  • Results of experiments comparing different GNN architectures on three tasks from the literature are presented, based on re-implementations of baseline methods.
