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. http://www.iotword.com/5105.html

You can think of … WebI tried to make the sigmoid steeper by creating a new sigmoid function: def sigmoid(x): return 1 / (1 + torch.exp(-1e5*x)) But for some reason the gradient doesn't flow through it (I get NaN). Is there a problem in my function, or is there a way to simply change the PyTorch implementation to be steeper (as my function)? Code example: bucknam \u0026 conley
