- GraphSAGE does inductive representation learning to deliver great recommendations for users with very little interaction data such as first or second time visitors
- ID-GNN is a training process that enables the model to learn patterns such as repeat purchase or brand affinity
- PNA introduces a variety of aggregation operators which are explored by Kumo AutoML
- GCN describes mean-pooling aggregation, which captures similarity between users with similar item purchases
- GIN captures frequency signal to learn more complex user behavior like power users vs resurrected users
- NBF networks reduce the computational cost of models, by providing an efficient way to capture paths between nodes
- GraphMixer uses temporal representation learning, to interpret sequences of user actions such as on-site browsing history
- RDL introduces temporal sampling, which learns from past sequences of user actions to predict the future.
