Question about the function get_degree_supports() #2

Closed Charlie1994 closed 5 years ago

Hi, I am currently having trouble in understanding the function get_degree_supports() in utils.py. From my understanding the function is used for getting adjacency matrices for node neighbors. But I am quite confused about the for loop and dot product used in this function, it seems it's used for getting neighbor adjacency matrices from different orders?

I am looking forward to your explanation. Thank you very much!

Yes, the for loop is used to compute adjacency matrices of different orders. For this paper we ended up using only 1st order adjacency matrix, setting k=1.
