Wrapping Up The creation of code libraries such as TensorFlow and PyTorch for deep neural networks has greatly simplified the process of implementing sophisticated neural prediction models such as convolutional neural networks and LSTM networks.
WebJun 18, 2024 · The solution consists in using a simple algorithm: first, initialize all the layers with orthogonal initialization. Then, take a mini batch input and, for each layer, compute the standard deviation of its output. Dividing each layer by the resulting deviation then resets it to 1. Below is the algorithm as explained in the paper: 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.
