Session: Building Scalable Graph Models for Search and Recommendation
Graph based neural models have garnered a lot of attention over the past few years especially in Search and Recommendation technology. Large global web companies like Amazon, Facebook, LinkedIn and Google use graph based models both in production and offline to develop robust representations of their existing knowledge graph systems. In this talk, I will be going over the foundations of GNNs (Graph Neural Networks) and methods to build scalable graph based models for downstream production applications.
- Understand foundations of graph based models- message passing and aggregation in GNNs, relational-GCN models, node-embedding methods
- Identify how graph based models can be used in the Search and Recommendation space (Incorporating Knowledge Graphs, link prediction as a generalized recommendation problem, some industry use-case examples)
- Review methods to scale and productionize GNN based models (distributed graph models, distributed inference, available GNN training platforms, serving GNN model representations)
