Hi ChloeKiwi,
Essentially, GNet provides domain embeddings for the encoder. The domain embedding serves as an identity of each domain, while also contains domain graph information (it is trained with the domain graph). "use_g_encode" decides whether we will use the pretrained domain embedding ("True" for using the pretrained embedding). The domain embedding can be pretrained or trained with the pipeline together. I will add some comments for this part.

Thanks a lot ! I am so sorry that I saw it just now.😥 And may I ask why it only sample several nodes to train the discriminator instead of all nodes?

Because we found that this can provide better performance compared with sampling all the nodes. You can also test it by adjusting the sample numbers in "opt.sample_v".

How to train DomainGraph with another dataset? MNIST... Use similarity?

Hi cht619,
Yes, you can use similarity to construct a graph. To use GRDA, you should have a pre-defined domain graph first. For instance, when you adapt the weather prediction model between states in USA, you can use the USA map as the graph; for MNIST, may be you can construct a graph based on similarities between number "1" to "9" (assuming each number forms a domain).
