Is it useable for heterogeneous graph? #3

Dear authors,

I am wondering is GraphSVX also useable for heterogeneous graphs? Thanks

Hi,

GraphSVX is applicable on heterogeneous graphs and makes complete sense. However, it does not distinguish between node / edge types in its explanation, so if you want explanations per node type for instance, you may have to do some post-processing yourself (e.g. aggregating the importance scores per type at the end).

Hope this helps, Alexandre

Hi Alex, Thanks for your reply. I was wondering is there any API in this repository that is compatible with other heterogeneous graph APIs such as the DGL package? Or could you please give an example on how to use GraphSVX in heterogeneous graphs? Thank you so much!
