Installing PyTorch WebMar 12, 2024 · Basically the bias changes the GCN layer wise propagation rule from ht = GCN (A, ht-1, W) to ht = GCN (A, ht-1, W + b). The reset parameters function just determines the initialization of the weight matrices. You could change this to whatever you wanted (xavier for example), but i just initialise from a scaled random uniform distribution.
