Hi, sigma is set according to the variance of the distances between each node. So sigmas for different datasets are different.
@Kaimaoge Thanks for your answer. BTW, there are thresholds for adjacency matrix for each dataset, how you set them ? (maybe measure degree fore each node...?)
Thanks.

For METR-LA and PEMS-Bay, thresholds are 0.1. We set it according to the original paper using those two. We didn't use thresholds for other datasets.
@Kaimaoge Thanks!
Hello. I am YJ Hong.
In appendix material in IGNNK paper, there are different sigma settings for different datasets respectively when constructing corresponding adjacency matrix.
Can you let me know how you set sigma ?
For example of NREL dataset, sigma for adjacency matrix is set to 7.5km and I cannot figure out why this value came out.
Thanks in advance.
