What is RNN PyTorch?
Basically, Pytorch rnn means Recurrent Neural Network, and it is one type of deep learning which is a sequential algorithm. In deep learning, we know that each input and output of a layer is independent from other layers, so it is called recurrent.
What is output of RNN in PyTorch?
RNN has two outputs - out and hidden . out is the output of the RNN from all timesteps from the last RNN layer. It is of the size (seq_len, batch, num_directions * hidden_size) . If batch_first=True , the output size is (batch, seq_len, num_directions * hidden_size) .
Why LSTM is better than RNN?
LSTM networks combat the RNN's vanishing gradients or long-term dependence issue. Gradient vanishing refers to the loss of information in a neural network as connections recur over a longer period. In simple words, LSTM tackles gradient vanishing by ignoring useless data/information in the network.
