WebBuild the Neural Network. Neural networks comprise of layers/modules that perform operations on data. The torch.nn namespace provides all the building blocks you need to build your own neural network. Every module in PyTorch subclasses the nn.Module . A neural network is a module itself that consists of other modules (layers). WebThis will complete the forward pass or forward propagation and completes the section of RNN. Let’s now do a quick recap of the working of RNN. RNN updates the hidden state via input and previous state; Compute the output matrix via a simple neural network operation that is W x h; Return the output and update the hidden state
