Will the nodes' hidden features be updated in backward propagation ？ #206

Open Qksidmx opened 2 years ago

Qksidmx commented 2 years ago

Hello，

    Recently, I started learning GCN managed to run examples codes.
    I konw that in forward propagation stage, the hidden features will be computed with learnable parameters W and aggregated with neighbors' feature. And parameters W will be updated in backward propagation stage.
    But I wondered that will the hidden features be updated in backward propagation stage? I try to search on the Google to find out , but got nothing.
    So, could someone tell me whether the hidden features will be updated in backward propagation stage?

thank,you!

I am wondering about why "bachpropagation will change the hidden features"? That should not be happened. BP will only update the weight matrix you defined in your layer.
