the difference between node and vertex #50

Open tanjia123456 opened 3 years ago

I'm sorry to bother you could you please examplain the the difference between node and vertex? My datasets is mindboggle(brain) contain the vertex. Many code are use node, So I feel very confused.

Hello,

there isn't really a difference between a node and a vertex. Some people use the word "node" and others use the word "vertex", but both have the same meaning.

but my vertex is 3d coordinate, there is no matter?

you can encode spacial dimension coordinates as node feature vector elements if you'd like to keep that information.

@gcucurull Hello, every person's brain can be represented by a graph, and there are a total of 80 people's data(80 subjects). As far as I know, the original GAT is to divide the data set of nodes, but here I want to divide the data set according to the subject. May I divide the first 70 subjects into the training set and the last 10 into the test set, so how do I use GAT for training? I want to use GAT for image segmentation. Please take the time to guide me the following, it is greatly appreciated.
