Two paper suggestions

[gcorso]

Hi, thanks for the great collection!

I would like to point out our recent works

• "Principal Neighbourhood Aggregation for Graph Nets". NeurIPS 2020 (paper, code)
• "Directional Graph Networks". Oral at DiffGeo4DL workshop NeurIPS 2020 (paper, code)

I think they would both fit perfectly in the analysis section.

Thank you very much!
