Question about label propagation

[xnuohz]

In your implementation of label propagation, do we need to update res for each propagation? Since res is always the initial y in each propagation.

I guess this depends on how you implement the Label Propagation model. We follow this code to implement it.

In general, adding residuals to the initial labels makes a lot of sense, as it avoids that labels are smoothed too heavily, e.g., in each iteration we re-inject the ground-truth labels to the output to some extend. This will help the model to make better predictions on nearby nodes in homophily graphs.

ok, thanks:)
