Excited to share a blog post on the connection between #Transformers for NLP and #GraphNeuralNetworks (GNNs or GCNs).

The key idea: Sentences are fully-connected graphs of words, and Transformers are very similar to Graph Attention Networks (GATs) which use multi-head attention to aggregate features from their neighborhood nodes (i.e., words).

This connection known to most people, but I've missed having all the information in one place. So I wrote it myself.

I'd love to get feedback and improve this post!

At our lab, we've already had success taking the Transformer architecture and applying it to graphs, e.g., for graphs of drawings/sketches.

In Part 2 (coming soon), I will use the @huggingface Transformers library to implement a simple GNN-like Transformer for language modelling and beyond.
