Compressed & combined representation of nodes + network
Kipf & Welling (2016)
How is this useful
a.k.a., questions we can (will be able to) ask
how much can we compress network + features
(down to what dimension)
how well does feature set 1 + network structure predict feature set 2
(and how much does network structure help in predicting)
→ relative importance of network/feature in predicting links or clusters
